Answer:
A cell that has Damaged p53 gene , A) may become Cancerous; B) may experience uninhibited and out of control cell division; C) may accumulate multiple mutation.
Explanation:
- p53 gene is a tumor suppressor gene that encodes a polypeptide that acts as a transcription factor.
- Mutation in p53 is associated with 50% of human cancers.
- Loss of p53 removes DNA damage check point.
- Mutation in p53 prevents DNA repair and the apoptosis of cells that contain irreparable damage.
- as a result the cells may accumulate multiple mutations.
- Since Functional p53 promotes DNA repair and arrest the cell cycle if a damaged DNA is present; any mutation in p53 may result in uncontrolled cell growth and tumor formation.
<span>Rivers can be polluted by nitrates because the fertilizers in the field that contain nitrates are washed into the river because of rain and flooding. Other source of nitrate pollution in the rivers is the mixing of sewage which contains human and animal wastes.</span>
The answer is C. lipid membrane
The reason for this is, as stated in your question, it is called a phospholipid bilayer.
It's called like that because it is made out of lipids and it also has phosphate groups, while the bilayer part means it just has two layers. Therefore it is commonly also called a lipid membrane.
Answer:
If blood glucose is high insulin is low
Explanation:
Answer:
Ocean desalination, Using nuclear fusion as an energy source and using stem cell technology to cure disease.
Explanation:
Ocean desalination is the major problem that occurs due to removing of nutrients that is present in the ocean water because of human activities. These nutrients are essential for the marine animals so for solving this problem, we should use other alternative energy resources in order to reduce ocean desalination. Using nuclear fusion as an energy source is a good idea but it can't be implemented on the earth because it requires 100 million degrees Celsius which is impossible to generate. Using stem cell technology to cure disease is a great idea which can cure many diseases in the human body. This available technology is used by replacing damaged cells with the healthy cells.
