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.

Humans release carbon dioxide that plants need; plants provide oxygen that humans need.
Tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human.
Remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals.
The humans releasing carbon dioxide, tapeworms entering a human’s intestines or remora sharks attaching themselves to whales are examples of mutualism, parasitism, and commensalism.
What is mutualism?In mutualism, humans release carbon dioxide that plants need; plants provide oxygen that humans need as both species benefit from the interaction. In parasitism, tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human one species benefits at the expense of the other.
In commensalism, remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals as one species benefits from the interaction, while the other is neither helped nor harmed.
Therefore, humans releasing carbon dioxide, tapeworms entering a human’s intestines through contaminated water and stealing nutrients from the human or remora sharks attaching themselves to whales are examples of mutualism, parasitism, and commensalism.

What are Amino acids? How are they bound?
Explanation:
Amino acids are organic compounds that contain amino and carboxyl functional groups, along with a side chain specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, although other elements are found in the side chains of certain amino acids
Each amino acid is attached to another amino acid by a covalent bond, known as a peptide bond. When two amino acids are covalently attached by a peptide bond, the carboxyl group of one amino acid and the amino group of the incoming amino acid combine and release a molecule of water.

Relationship between Genes and deoxyribonucleic acid are that - Genes are created of Proteins, which give directions for creating deoxyribonucleic acid.
What is DNA?DNA stands for Deoxyribonucleic acid that may be a chemical compound composed of 2 polynucleotide chains that coil around one another to create a spiral carrying genetic directions for the event, functioning, growth and replica of all renowned organisms and plenty of viruses.
DNA is the hereditary material in humans and most different organisms. Nearly each cell in every person’s body has an equivalent deoxyribonucleic acid.
DNA was discovered by famous Scientist Watson and Crick in the year 1950.
Most deoxyribonucleic acid is found within the nucleus (where it's known as nuclear DNA), however a tiny low quantity of deoxyribonucleic acid can even be found within the mitochondria (where it's known as mitochondrial deoxyribonucleic acid or mtDNA).
The information in deoxyribonucleic acid is hold on as a code created of four chemical bases: Adenosine (A), Guanine (G), Cytosine (C), and Thiamine (T).
Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism.
DNA bases combine up with one another, A with T and C with G, to create units known as base pairs. Every base is additionally hooked up to a sugar molecule and a phosphate molecule.
Together, a base, sugar, and phosphate are known as a Nucleotides. Nucleotides are organized in 2 long strands that type a spiral known as a Double Helix .
The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.
An important property of deoxyribonucleic acid is that it will replicate and create copies of itself. Every strand of deoxyribonucleic acid within the spiral will function as a pattern for duplicating the sequence of bases.
This is vital once because cells divide as a result of which every new cell must have a certain copy of the deoxyribonucleic acid within the previous cell
What is a gene?A Gene is the basic physical and purposeful unit of heredity created of deoxyribonucleic acid.
Some genes act as directions to create molecules known as proteins. However several genes don't code for proteins.
In humans, genes vary in size from a couple of hundred deoxyribonucleic acid bases to quite two million bases.
Gene is a basic unit of heredity and a sequence of nucleotides in deoxyribonucleic acid that encodes the synthesis of a factor product, either RNA or Proteins.
Genes will acquire mutations in their sequence, resulting in totally different variants, called alleles, within the population.
These alleles cypher slightly totally different variant of proteins that cause totally different composition traits.
Genes evolve because of action / survival of the fittest and genetic drift of the alleles.
An endeavor known as the Human order Project, that worked to see the sequence of the human order and determine the genes that it contains, calculable that humans have between 20,000 and 25,000 genes.

anabolic metabolism is most similar to:
a. a car crashing into a wall at high speed
b. asexual reproduction in amoebas
c. a pump pushing water through a pipe
d. building a house of bricks
Answer:
Metabolism is defined as all the various processes in the body, which yield energy for the proper functioning of the organs and body. metabolism can be categorized into anabolism and catabolism. The correct option is building a house of bricks.
Explanation:
Anabolism is defined as the ‘building up’ of compounds, molecules, or other substances. The example that best explains anabolism is building a house of bricks. Anabolism is the synthesis of complex substances from simpler or monomeric units. Anabolism is termed as constructive metabolism, such that the complex molecules formed from simple molecules have stored form of energy.
A car crashing into a wall at high speed determines the breakdown of resources, such as walls, bricks, and cars. The crashing of the car can resemble catabolism, which is defined as the breakdown of complex substances into smaller substances.
Asexual reproduction is a biological process in which offspring are clone to the parent cell. In amoeba, the parent cell splits into two daughter cells, which have the same genetic information as the parent cell. The splitting of the parent into daughter cells is termed binary fission. The process resembles catabolism.
The pump pushing the water from a pipe is a type of example of pressure difference. The water flows from high pressure to low pressure, which results in the pushing of water out of the pipe. Thus, the activity does not exhibit any type of metabolism.
