Answer:
1. I can’t think of the percentage off the top of my head, but I have the rest of the answers:
2. By cutting down trees, you are releasing the carbon dioxide that the trees were previously storing, and deforestation also limits the amount of trees available to take part in photosynthesis.
3. In order to have agriculture, you must have land to grow the food on; in order to get this land, some people need to burn jungles and rainforests for more space (what‘s currently happening in the Amazon).
4. Set incentives for the government. This encourages them to not chop down trees, as there will be a visible benefit.
5. I would say education. It’s difficult in less developed countries, because it truly is all that they rely on; but through education, people can at least be aware of what they are doing so when the time comes they will be able to stop it.
Explanation:
Answer:
Red blood cells are the type of cells which are responsible for the transportation of oxygen and carbon in the body.
White blood cells are the type of cells which are responsible for the protection of body against pathogens such as bacteria and viruses etc
Platelets are those cells which helps in blood cloting after injury.
Plasma is a liquid medium in which nutrients, water and blood cells are present. Its main function is to transport nutrients to the body where it is required.
<span>Cells control cell division in order to maintain normal cell function. If something happens to the control of the cell division, the healthy cells will divide uncontrollably. These new cells are cancer cells. </span>
The mutations in three genes are responsible for development of cancers:
1. Mutation in proto-oncogenes. Proto-oncogenes normally signal cells to grow and differentiate. Proto-oncogenes can become oncogenes due to mutations which result in the uncontrollable division of the cells.
2. Mutation in tumor suppressor genes. In normal cells, tumor suppressor genes suppress genes essential for cell cycle and that way they prevent uncontrollable cell division. However, after a mutation in these genes, suppression is lost and the cell may progress to cancer.
3. Mutation in stability genes. In normal cells, they have no role either in cell death or growth, but they control mutation rate. Mutation in stability genes results in situation where all genes, including proto-oncogenes and tumor suppression genes, are more frequently mutated.
