PLS HELP!!!
Cells are capable of reproducing themselves by cell division. For single celled organisms, cell division is essentially reproduction. For multicellular organisms, division is necessary for growth and renewal. Even though cell division is natural and necessary, what happens when the rate of cell division becomes too rapid and out of control? How can we get rid of such rapidly dividing cells in the human body?

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.

In North American forests, two species of birds, nuthatches and brown creepers, forage on the same trees for insects. Brown creepers feed on insects found near the bottom of the tree trunk, while nuthatches feed on insects in the top part of the tree. The difference in foraging behavior most likely affects the nuthatches and brown creepers by -


A) Establishing dominance between the birds for nesting sites


B) Reducing competition between the birds for resources

B) Allowing the birds to avoid many types of predators

C) Preventing the birds from interbreeding with each other

So, since when do we start burying survivors alive? Did they crash into Zombiland? Was it Spirit Air who didn’t want to pay damages in law suits? Or is this a time distance question in which we have to wait until each of the surviving passengers pass away? If so then I suspect that those who survived the New Mexico/Texas border crash would be buried in the state or country in which they eventually died or where they so instructed their next of kin to bury them. Of course, maybe they would be cremated and then the ashes will sit on someone’s mantel until a house cleaner tosses them out or they ashes may be spread out over a special parcel of land or water.

The Treg cell destroys the Tc or Th cell rather than the Cell presenting self antigen because the Treg cell needs to: destroy T cells with receptors that respond to self-antigen. avoid reacting itself to self-antigen passed along by the Cell presenting self-antigen. destroy the self antigen, and it must destroy the cell in order to do this. preserve the cell in the middle that is presenting self-antigen.
