Answer:

Small proteins are called peptides

Explanation:

Both peptides and proteins are made up of strings of the body's basic building blocks – amino acids – and held together by peptide bonds. In basic terms, the difference is that peptides are made up of smaller chains of amino acids than proteins. As a general rule, a peptide contains two or more amino acids.

Answer:

i think a cell is zoomed in

Explanation:

The following formula is useful to determine the size of the cell ⇒ Size of the object = FOV / Fit number = dFOV / Fit number. If you have this data, you can estimate the size of the onion cell. According to the values we used, the estimated size of this onion cell is 112 μm.

-----------------------------------------------

Cells are too small to measure their sizes, so to know their actual size, we can make mathematical estimations to know their sizes, or we can use software programs. In this case, we are estimating their size using the following formula,

Size of the object = FOV / Fit number = dFOV / Fit number

To answer this question, we will replace the terms in the given formula.

→ First, we will get the FOV value. From references, we can assume that

You can also calculate the FOV by using a millimeter paper or rule.

Note: We will use these values to replace terms in the formula, but you can use the dFOV value calculated in question no. 3.

→ Second, we will count the number of cells that fit the field. We can see about four cells across the field of view.

→ Finally, we will replace the terms in the formula.

Size of the object = FOV / Fit number

Size of the object = 0.45 mm / 4

Size of the object = 0.112 mm

Since we generally use μm when referring to cell sizes, we need to multiply 0.112 x 1000 to get the size of the cell expressed in μm.

Size of the cell (μm) = 0.112 mm x 1000 = 112 μm

Answer:

Here are 5 important things you should know about cancer cells:

1. Everyone has cancer cells in their body. These cells are not detected in routine tests until they have multiplied and grown to billions of cells.

2. Cancer cells are present in the body about 6-10 times in a person's lifetime.

3. When the immune system is healthy, cancer cells will be destroyed, preventing tumor growth and formation.

4. When a person has cancer, it means that he or she may be suffering from severe nutritional deficiencies or due to toxic environmental factors, unhealthy lifestyles and diets.

5. An effective way to fight cancer is to starve cancer cells by not providing them with the food they need to proliferate and grow.

"3 golden rules" help kill cancer cells:

1. Diet to prevent cancer

It can be said with certainty that there is no better way to keep your immune system healthy than with a reasonable and scientific diet. So ask yourself the question "Do you really have a reasonable diet to prevent cancer?". And here are the essential suggestions.

- Increase your diet with fresh vegetables, fruits, whole grains and foods high in fiber.

Eat more antioxidant foods: The fruits below are rich in antioxidants.

In addition, all vegetables and fruits contain a lot of vitamin A (carrot, papaya, tomato, sweet potato, pumpkin), vitamin C (orange, cherry, kiwi, strawberry), vitamin E (avocado, papaya). , cashews, peanuts, sunflower seeds, almonds...) are also foods with strong antioxidant capacity to help prevent cancer.

- Increase vitamin D supplementation.

Vitamin D is a special vitamin that is more important than all other vitamins because of its "universal" effect on the body's immune system. Its biological effects are related to the expression of more than 3000 genes in the body.

In addition to the extremely important role for the musculoskeletal system, the role of vitamin D in the prevention of many cancers and infectious diseases has been scientifically proven.

More than 90% of vitamin D in the body is synthesized in the skin under sunlight. Very little is absorbed from the diet, so the daily diet cannot guarantee the full amount of vitamin D needed by the body.

A recent study by a joint research team between the 108 Central Military Hospital and the University of Tuebingen (Germany) published in the journal BMC Infectious diseases showed that about 90% of healthy people are deficient in this vitamin. plasma vitamin D concentration <30 ng/ml).

Research also shows that there is a strong association between vitamin D deficiency and liver cancer in patients infected with hepatitis B. So the simplest way to ensure that you do not have a deficiency is to take vitamin D supplements. daily dose of 10-20 (µg/day) for all ages.

- Do not eat a lot of sugar and sweets because this is a food source that helps tumor growth. Sugar, not protein, is what tumors need to grow, so people with cancer still need the protein found in meat to boost their health against cancer. However, it should be noted that you should not eat a lot of red meat but should eat chicken and fish instead of beef and pork.

2. Increase physical activity

This is the most important principle of strengthening the immune system that anyone can do. The largest study conducted by the National Cancer Institute (USA) on more than 1.4 million people found that regular physical activity reduces the risk of 13 common types of cancer in humans.

The link between physical activity and reduced risk of many types of cancer can be explained by several key mechanisms:

- Strengthen the immune system, prevent the growth and spread of infectious agents.

- Physical activities help increase metabolism, improve circulation and help transport oxygen to all organs. Cancer cells must not grow in an oxygen-rich environment because oxygen can kill cancer cells.

Lowering levels of hormones such as insulin, estrogen and growth factors are thought to be closely related to cancer formation and development.

- Control weight, prevent obesity: Obesity is a leading risk factor for many types of cancer, metabolic disorders, cardiovascular diseases... It is estimated that more than 500,000 cancers are diagnosed each year. obesity-related diagnoses.

Increased blood flow to organs such as the liver, kidneys and intestines enhances the efficient elimination of waste products and toxins that can be potential causes of cancer from the body.

An attic environment is a hot and muggy place, with few fresh breezes coming in. Meanwhile, the equator is a very dry and low altitude location that has lots of fresh air and major wind currents constantly circulating through. This exchange of air allows for natural temperature regulation- warm air rises to the updrafts at equatorial latitudes and cold air sinks around Antarctica . At a higher latitude like the United States, there are fewer major winds like monsoons or cyclones to provide this necessary "push" for different atmospheric temperatures over time. With little variation in climate (weather) patterns, there is also less need for sweating as moisture evaporation cools down your skin (thermoregulation).
