Smiley Faces – Smiley icons – Smiley Symbols – Smiley Face Symbols – Smilies, smiles, emotions, emoticon and happy smile face icons. The classic image was originally developed in 1963 and included a yellow circle with two black dots for eyes and an arc representing the mouth. Yellow Smiley Symbols are widely used emoticons as signs of happy faces and one’s positive and other emotions.
Weight Loss is an intentional or unintentional reduction of the body mass, mostly due to a loss of body fat, fluid, muscle. Intentional weight loss requires a conscious effort to improve an actual or perceived overweight body by dieting and/or undertaking physical activity.
Dieting without proper nutrition and detoxing may result in rebound to the original weight. Proper dieting and nutrition, lifestyle changes and physical activity all help weight loss to be sustainable. Weight loss diagram below shows this effect.

The muscular system diagram depicts the anatomy of various human muscles including biceps, tripezius, deltoid, triceps, abdominis (abs) and other key muscle groups. While multiple groups exists, overall, there are 3 different types of muscle tissues: skeletal, visceral and cardiac.
Skeletal muscles are attached to the bones, often via a joint with muscles used to bring the bones closer together. They are usually attached to the skeleton. These muscles are also controlled consciously by a human while performing such tasks as running, speaking and typing. The cells in these skeletal muscles are made of multiple progenitor cells coming together into the long and strong fibers. The diagram below summarizes skeletal muscles.
Visceral muscles are the weakest of all muscles and are a part of the organs and body systems such as blood vessels and stomach. They are used to move matter through the organ (e.g. blood, food, etc) and appear smooth and uniform when looking at the microscope. They are unconsciously controlled by the brain.
Cardiac muscle is located in the heart and pumps blood through the arteries. Similarly to visceral muscles, it is not controlled consciously; instead it stimulates itself while adjusting to the hormone levels. Cardiac tissue is very strong.

Nerve Cell Diagram below is a typical illustration of this type of a human cell that makes up the cells in the nervous system. Nerve cell parts include nucleus, soma, dendrite, axon, myelin sheath, axon terminal, node of ranvier. This composition of the cell ensures that the neuron is functional with chemical signals transmitted to neighboring neurons.
All nerve cells respond to the external stimulus with an electric discharge that produces an electrical pulse of about 50-70 millivolts. This pulse is often referred to us an action potential. The electrical pulse travels down axon, which is the the fiber-like extension of the nerve cell. The speed of the impulse is about few tens of a meters per second and is a function of the fiber size. The transmission can be sent to a nearby nerve cell via a chemical neurotransmitter as soon as it gets to the axon terminal bundle. These types of nerve cells can be found all over the human body.
Bike frame size and seat height chart below shows the dimensions of the frame size and seat height based on the inseam height. To choose the right bicycle and adjust the height of the saddle, first measure inseam height and then multiply the value by 1.08, which will give you the seat height (see the table below). This measurement can be used for both mountain and road bikes.
Getting the right bike size is important to maximize your speed, comfort and ability to handle, i.e. all the the things needed to ensure you get the best possible biking experience. It is important to use your personal measurement such as your height to choose the right bike frame and seat height. The bicycles are measured by the length of the seat tube, i.e. the tube where the saddle slides in to. Road bicycles are usually measured in cm while mountain bikes in inches. The diagram below will assist you with choosing the right bicycle regardless of the measurement system you are more accustomed to.

Circulatory System is responsible for delivering oxygen, water and nutrients to various body systems and cells while also transporting waste away (e.g. carbon dioxide). The circulatory system consists of the heart, blood vessels such as aorta, vein, ventricle, capillaries and blood itself.
The heart is essentially a muscle that pumps blood ensuring its movement throughout the body. The heart is located a bit to the left from the center of one’s chest. Well functioning circulatory system depends on a health heart, which in turn is dependent on regular exercises, healthy eating and not smoking.
The blood vessels carry blood throughout the body. The blood flows away from the heart through arteries. Arteries carry blood high in oxygen content. Veins on the other hand carry blood towards the heart. Capillaries are small blood vessels that connect arteries to veins. Nutrients, oxygen, water and carbon dioxide pass through the capillary walls.
The blood is the red substance that transports all the above throughout the body cells. The blood consists of red blood cells, white blood cells, platelets and plasma. Red blood cells carry oxygen from the lungs towards body cells and deliver carbon dioxide back. Carbon dioxide is than exhaled from the lungs. White blood cells help the body fight infections by destroying germs. Platelets are cells that stop bleeding by forming a natural seal to the damaged blood vessel. The red blood cells, white blood cells and platelets are formed by the bone marrow, which is a soft tissue in the bones. Plasma is the liquid part of the blood, produced in the liver, which makes about half of the blood content. All the above make up the circulatory system presented below:

Other auto parts are also illustrated on the below diagram.
Plot Diagram illustrates the typical development of a book plot. It consists of the exposition, rising action, climax, falling action and resolution. The exposition is the beginning of the story where the setting and the characters are first introduced to the reader. The setting is where the story takes place. Rising action represents the development of the story through the series of conflicts faced by the main characters. This leads to the climax or the peak of the story, where the main events occur. The falling action are the events that lead to the end of the story, i.e. how everything gets settled and main characters ‘recover’ from the main conflict. The resolution is the end of the story.
Most novels and books follow the above plot structure since it is most natural for story telling and human comprehension. At the same time, there are a few books and movies nowadays that try to break through this traditional narrative approach to writing literature. The below plot not only shows the stages of the plot but also the degree / severity of the conflicts.
Microscope diagram below depicts parts of a typical light or optical microscope. Microscope uses lenses and light to optically increase the size of an image of whatever is being magnified. This is achieved through a magnifying glass, which varies in magnification and quality. Other parts of a microscope include eyepiece lens, tube, arm, base, illuminator, stage, rack stop, nosepiece and a diaphragm. Lets discuss each component in more detail.
The Base is the bottom of the microscope. Arms support the tube and are attached to the base. The tube is what integrates the objective lenses to the eyepiece lens. The latter is what a user sees through and is located at the top of the microscope. There are multiple objective lenses in a microscope that come in a variety of magnification powers. The final magnification is a multiple of the eyepiece lens and the objective lens (e.g. 10x eyepiece multiplied by 40x objective gives you 400x magnification). The lens with the lowest magnification are called short and with the highest are referred to as long. The objective lenses are switched with a revolving nosepiece also called a turret. the relevant proximity of these lenses to the slide is adjusted by the rack stop.
Illuminator is the the source of light or a mirror. The mirror microscope uses light from outside to display the image. The light comes from bottom of the stage, which is a platform where slides are inserted between stage clips.
How to Focus a Microscope:
1) Start with the lowest power objective lens.
2) Put the lens down close to the slide.
3) View through the eyepiece and focus upward until the image is sharp.
4) Switch objective lenses for greater magnification while adjusting the focus knob.
Ear Diagram below shows the various parts of a human ear. Ear anatomy includes external, middle and inner parts.
The outside portion, called the outer ear includes pinna, a ridged cartilage, through which sound travels into the short tube called the external auditory canal. This canal goes all the way to the eardrum.
Sound waves vibrate the eardrum connected to the cochlea, part of the inner ear. Sounds are then converted into nerve impulses that are further conducted to the brain. The semicircular canals are attached to the nerves and cochlea in the inner ear and are filled with fluid. Their function is to communicate the position of the head and body’s balance to the brain. The eustachian tube allows fluid to flow from the middle ear into the throat.
Essentially, a human ear is a system consisting of three organs that work together on hearing and balance in conjunction with the nervous system. The diagram below displays the human ear anatomy.
Cell diagram: Human cell as most other animal cells make up the structure of the body. Cell diagram below is representative of a typical human cell responsible for carrying out various bodily functions and processing nutrients into energy used to sustain itself. The diagram shows the following elements: nucleus, membrane, ribosomes, lysosome, cytoplasm and others. Now lets explain what each of the cell parts is responsible for.
Cytoplasm is a part of the cell filled with cytosol liquid surrounding the nucleus. The nucleus is the center of the cell and acts as its control unit responsible for cell growth, division and maturity. Nuclear envelope is the membrane that surrounds the nucleus protecting the DNA from the rest of the cell.
The outside of the cell is protected by the plasma membrane. This membrane allows for passing of the nutrients and waste. An organ that ensures energy from nutrients can be consumed by the cell is called Mitochondria. The Golgi apparatus ensures molecules processed by the endoplasmic reticulum can be passed through the cell.
Peroxisomes and Lysosomes are responsible fore recycling of the worn-out cell parts while also breaking down bacteria and toxins. The cell diagram below lists various cell parts.
The Pregnancy stages diagrams below shows the development of the baby month by month in woman’s uterus. Month 1 marks the beginning of the first trimester when the ovulation and conception take place. During week 4, some pregnancy tests may detect conception. At this point, the embryo has just two cells. During the second month of pregnancy, women often feel fatique, morning sickness, hormonal fluctuations and other pregnancy-related symptoms The baby’s heart is beating and the brain is forming. During month 3, the embryo becomes a fetus and is about the size of a plum.
During the second trimester, starting month 4, the baby’s bones are hardening and the fetus is about 5 inches long and starts to resemble a human being as seen in the below diagram. Month 5, baby starts to kick and is developing hearing.
During the third trimester, the baby is fully forming with brain processing sights and sounds. The fetus is about 13 inches long. By month 8, the baby is fully formed and is increasing in weight. Baby’s lungs are almost fully developed. By month 9, the baby is ready to come out and meet the world! The month-by-month baby diagram shows the development of a baby and growth of mother’s belly.
Eye Colors: the colors of a human eye are dependent on the two main characteristics. The first characteristic that determines eye color is the pigmentation of the eye’s iris, the second is the frequency of light scattering in the stroma of the iris. Iris varies from light brown to black, the blue and green pigments are not found in the human iris, rather these colours are a product of lighting conditions.
The eye colors are based on genetics: blue, grey, amber, hazel, brown, green, black. Blue, grey and green eyes are rare; most of world’s population has brown eyes. The eye color chart below depicts various types of eyes. Many now use contact lenses of different colours to alter their appearance.
Human heart is a key organ in the circulatory system responsible for pumping blood through blood vessels. The heart is found slightly to the left of the center of the chest. As shown in the below diagram, it consists of four chambers: left atrium, right atrium, left ventricle and right ventricle. Multiple valves found in the heart ensure that blood flows only one way through the heart. The lining of the heart consists of three layers: endocardium, myocardium and epicardium.
The blood low in oxygen flows into the right atrium from the superior and inferior vena cavae and further flows into the right ventricle. From here it is pumped into lungs where it releases carbon dioxide and absorbs oxygen. Blood high in oxygen content flows back to the left atrium and then passes through the left ventricle. It is then pumped out via the aorta. Aorta and other arteries transport blood away from the heart. The blood also carries nutrients and waste between the digestive system and various body organs.
The heart is essentially a muscle that contracts at a resting rate of ~72 beats per minute. The lower the heart rate when resting, the better for the health and individual’s longevity. The heart rate may increase during exercising. However, regular exercises ensure that the rate slows down in the longer term.
The heart diagram below lists key parts of the heart.

Plant Cell is a basic block of the plant structure. The plant cell diagram below displays various parts of the cell including nucleus, cytoskeleton, cell wall, membrane, centrosome, central vacuole, chloroplast and others. Lets explain what each component is responsible for:
The nucleus is the commanding center of the cell controlling various functions of the cell and containing DNA. The nucleus is covered by the nuclear membrane. This is different from the cell membrane, which is a protein layer on the inside of the cell wall. The cell wall is a thick membrane that allows for passing of the nutrients and forms the structure of the plant together with other cells. The jelly material outside of the nucleus is called cytoplasm.
The key difference between plant cells and animals cells is the process of photosynthesis. Plant cells are able to convert sunlight, water and carbon dioxide into sugars (energy), oxygen and water. Photosynthesis takes place in the chloroplasts, which contains chlorophyll. Chlorophyll is a molecule responsible for this process and is usually green in color. The central vacuole stores sugars and water for cell’s use.

Fracking Diagram. What Is Fracking? Learn how fracking utilizes water to extract oil and natural gas from shale formations, why fracking is an economic and energy security solution. Hydraulic fracturing (fracking) is a well stimulation technique in which rock is fractured by a pressurized liquid, usually a water mixture. Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the deposit.
Fracturing fluid is a mix of water sand and chemicals is pumped into the well. The pressures causes the rock surrounding the pipe to crack. The proppants hold open these cracks to allow the trapped gas to escape. Gas / oil flows up the well to be extracted. Some potential risks include groundwater contamination and air quality degradation but with deposits usually located at great depths, these are usually do not present a big problem.

Hyperloop diagram – The hyperloop diagram displays the fundamentals of this new transportation technology. Is Hyper loop the transportation of the future over long distances? This may well be the case given its potential. Elon Musk played a key role in invention of the hyperloop concept.
Hyperloop’s key components are as follows the capsule, compressor, vacuum tube, propulsion, air bearings and the actual payload. Compressor is a giant fan on the front of the capsule and is what makes the hyperloop possible, transferring huge volumes of air away from the nose. Without it, the pod would be pushing all the air in front of it, which would make it a lot more expensive including the need to develop a bigger tube.
Speaking of the vacuum tube, capsule will travel in a near vacuum to reduce drag significantly. Valves and pumps will keep internal air pressure at about 100 Pascals or one-thousandth the air pressure at sea level. Nitrogen could be injected into the tube as well.
Propulsion: the Hyperloop capsule speeds along a magnetic river propelled by linear induction motors spaced along the tube or installed as a continuous strip. Linear induction, used on maglev trains has no moving parts and low maintenance costs.
Air bearings – the capsule will use cushion of air pumped from the bottom of lunch-tray-size sleds. Landing gear may need to be deployed as it comes to a stop.
Hyperloop payload will be a capsule of about 70 feet long, big enough to hold standard 40 foot container. The capsule could accelerate from 0 to 750 mph in less than 60 seconds.
Essay Structure – The below essay structure diagram explains how a typical essay should be structured including introduction, 3 key body paragraphs or arguments and conclusion. The creation of a good essay requires a lot of knowledge from the author but having a good structure helps to make the message even more clear.
Great arguments and knowledge structured poorly may result in audience losing focus and interest while even a fairly weak arguments structured well can result in getting reader’s attention.
The first paragraph, the introduction, starts with a general idea and gradually gets more and more specific. It ends with the thesis, one sentence that tells the reader what is the main point and argument of the essay. The triangle illustrates the general to specific / focused structure, gradually getting narrower and coming to the main point.
The body of the essay proves or elaborates the thesis further. Body usually has three paragraphs. The longer papers just add more body paragraphs but the overall structure works regardless of the length of the paper. Important to note that having too many arguments may result in reader thinking you are trying to ‘oversell’ your point and could result in loss of focus.
On the essay structure diagram below, the yellow portion in the red paragraph shows the location of the transitional phrase and so does the red segment in the orange segment.
It is best to place a good argument first to capture users attention. The weakest argument usually goes in the middle. Your strongest argument should go last so you finish on a strong note and get your reader to agree with you.
In the conclusion, the structure is reversed with the specific thesis coming first and the ever more general sentences coming last. It is important that the last sentence creates a good ending for the paper. Sometime this could be inspirational or a generic truism. Do not introduce new ideas in the conclusion.
Following this structure will help you write excellent essays. This is very important to get your ideas across. Communicating at one’s best ensures people understand each other. Communication is key to the betterment of our world. 🙂 Note how this last paragraph starts off with specific point and concludes in a generic inspirational phrase.
