Yes, human blood is green in the deep ocean. We have to be careful about what we mean by color. Objects don't really have an intrinsic color. Rather, the color of an object is determined by three factors: 1) the color content of the incident light that is illuminating the object; 2) the way the object reflects, absorbs, and transmits the incident colors of light; and 3) the way in which the detector such as your eye or a camera detects and interprets the colors of light coming from the object. In everyday life, the incident light (such as from the sun or from a light bulb) typically contains all colors of visible light in nearly equal proportions. Furthermore, the healthy human eye can detect all colors of visible light. For these two reasons, in typical circumstances, we can treat the color of an object as only depending on the properties of the object itself. However, once we move away from typical circumstances, we have to use the more complete description of color, which involves the light source, the object, and the detector. With this in mind, let's turn to the color of blood

The outer layer of skin cells on your finger does not detect anything. The outer layer of your skin contains cells that are dead. In fact, the outermost 25 to 30 cell layers of your skin consist of dead cells that do nothing beyond providing a physical barrier that keeps water in and chemicals out. Furthermore, all regular skin cells (keratinocytes), whether alive or dead, don't detect physical sensations since they are not designed to do this. Physical sensations that are experienced when touching an object are detected by special receptors that sit in lower layers of the skin. Such sensations include pressure, temperature, vibration, and skin stretching. Therefore, in order for you to detect a physical effect, it must first pass through all the layers of dead skin. For instance, in order for you to feel that a frying pan is hot, heat from the pan must travel through the outer layers of dead skin before it can reach the thermoreceptors nestled in the lower layers of the skin. The thermoreceptors then detect the heat and in response send an electrical signal along your nerves to your brain.

Doctors did not create your belly button (or navel). The navel is not the scar or knot left by a doctor that cut your umbilical cord at birth. This fact is obvious to anyone that has ever had children or bathed newborns, but it is sometimes misunderstood by others. While you were in your mother's womb, your umbilical cord attached to your navel at one end and to your placenta at the other end. The placenta is a pancake-shaped mass of blood vessels that attaches to the wall of the mother's uterus. Food that your mother ate and oxygen that she breathed went into her blood, and then was carried to her uterus. Where your placenta and your mother's uterus touched, the food and oxygen was exchanged from your mother's blood to your blood. Your blood than carried the nutrients from the placenta, down the umbilical cord, through your navel,

Healthy humans use all of their brain. There is no part of the brain that goes unused. Certain tasks work certain parts of the brain more, but they all play important roles, as explained by neurobiologist Dr. Eric Chudler. Brain maps, as found in modern anatomy books, indicate that each part of the brain has a specific function essential to a healthy human. If there were a part of your brain that really went unused, then you could safely damage that part in an accident with no ill effects. But decades of medical records show that damage to any part of the brain has severe effects. If 90% of the brain were not used, then 90% of the brain tumors would cause no problem. Imagine brain doctors telling 90% of their cancer patients, "I have good news and bad news. Bad news: you have a brain tumor. Good news: it's in the part of the brain that you will never use." The thought is absurd.

Humans can taste more than four flavors on their tongue. Depending on how narrowly you define "taste", there are between five and several dozen independently experienced sensations on the tongue, according to the book "Taste and Smell: An Update" by Thomas Hummel. The seven most common flavors in food that are directly detected by the tongue are: sweet, bitter, sour, salty, meaty (umami), cool, and hot. Note that "cool" and "hot" tastes do not refer to actual low or high temperatures being present, but rather to foods that chemically trigger a sensation that is similar to cool or hot sensations. Sweet flavors come from things like candy and fruits. Bitter flavors come from many vegetables and unsweetened chocolate. Sour flavors are contained in anything with acid, such as citrus fruits or vinegar. Salty flavors obviously come from anything with salt, such as chips or nuts. Meaty flavors come from anything with glutamates such as soy sauce, cheese, and meat. Cool flavors come from certain chemicals such as in mint and menthol. Hot flavors come from other chemicals such as in chili peppers and black peppers. Beyond these seven basic tastes, there are several other flavors that researchers have found receptors for, including calcium, dryness, fattiness, heartiness, and numbness. But returning back to the original question, it is true that humans experience far more flavors than the tongue can detect. The reason for this is that the nose plays an integral part in the experience of taste, and the nose can detect thousands of different smells.

Yes, poppy seeds contain narcotics. Poppy seeds are used to add flavor to many baked goods, salads, and pasta dishes; ranging from lemon bread to chicken salad. Poppy seeds are produced by the opium poppy plant, a plant that has been famous since ancient times for containing psychoactive chemicals. All parts of the opium poppy, including the seeds, contain the drugs morphine and codeine. In fact, eating poppy seeds can lead you to test positive on a drug test. Many government agencies know this fact and therefore discourage people from eating poppy seeds who are required to take drug tests. The official inmate furlough application of the US Federal Bureau of Prisons requires the following pledge:

Despite the fact that the name "koala bear" is used in the popular culture of some countries, koalas are actually not bears. The more accurate name of "koala" is used in this animal's native land of Australia. Koalas are marsupials, just like kangaroos and possums. Like most other marsupials, koalas give birth to babies that are not fully developed and carry their young around for the first few months in a pouch. Koalas are known for being picky eaters and having a diet that consists almost entirely of Eucalyptus leaves. Unfortunately, Eucalyptus leaves do not provide much energy, so koalas typically sleep for 20 hours a day and lead a sedentary lifestyle. Because koalas are not bears, they do not share the opportunistic omnivorous habits of bears. They do not eat honey, ants, nuts, or fish like bears do. Koalas are only found in Eastern and Southern Australia. The work titled The Koala Book by Ann Sharp states, "Its established scientific name is Phascolarctos cinereus, which literally means 'ash-grey pouched bear' and until quite recently koalas were commonly referred to as 'koala bears'. Koalas may resemble teddy bears but the comparison ends there. Koalas are not bears, they are marsupials, although their scientific name will continue to confuse as it is almost impossible to change."

Yes, blind people do indeed dream in visual images. For people who were born with eyesight and then later went blind, it is not surprising that they experience visual sensations while dreaming. Dreams are drawn from memories that are stored in the brain as well as from brain circuitry that is developed while experiencing the outside world. Therefore, even though a person who lost his vision may be currently blind, his brain is still able to draw on the visual memories and on the related brain circuits that were formed before he went blind. For this reason, he can dream in visual images. What is more surprising is the discovery that people who were born blind also dream in visual images.

Yes, there are nuclear reactions constantly occurring in our bodies, but there are very few of them compared to the chemical reactions, and they do not affect our bodies much. All physical objects are made of molecules. A molecule is a series of atoms linked together by chemical (electromagnetic) bonds. Inside each atom is a nucleus which is a collection of protons and neutrons linked together by nuclear bonds. Chemical reactions are the making, breaking, and rearranging of bonds between atoms in molecules. Chemical reactions do not change the nuclear structure of any atoms. In contrast, nuclear reactions involve the transformation of atomic nuclei. Most of the processes surrounding us in our daily life are chemical reactions and not nuclear reactions. All of the physical processes that take place to keep a human body running (blood capturing oxygen, sugars being burned, DNA being constructed,etc.) are chemical processes and not nuclear processes. Nuclear reactions do indeed occur in the human body, but the body does not use them. Nuclear reactions can lead to chemical damage, which the body may notice and try to fix.

Dear aspirant..

Hope you are doing well. To make notes keep some points in your mind. Follow the tips

• F or Biology, write only those points in your notes which you find are forgetful . For instance, I always used to forget the stored food of various algae, so I just wrote that one point in my entire notes of Biological Classification. Add all the miscellaneous points and lines of the NCERT to your notes.
• Don't prepare notes just after starting off with a chapter. The very first thing students should keep in their mind is that don't make revision notes simultaneously after studying the chapter for the first or second time. This is the thing where most aspirants go wrong. Go through each and every NEET 2022 important topic of that chapter at least four to five times, so that it is easy to know what is actually important and what is not. Because it is the last phase and hard work requires time here smart work will make the difference.
