Skin serves as a protective barrier, a way to sense the world, and a layer that keeps nutrients and water inside the body. Four types of cells make up the skin, and they are produced mainly in the epidermis near the basement membrane.
It’s more useful because you can see that animals eat more then one type of food and that if one animal dies out that you can see the animal that eats that animal can still love because there’s other animals it eats
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.
Answer:
there are more electrons than protons
Explanation:
If a cell that has three pairs of chromosomes, the fraction of the gametes produced from this cell will contain only maternal chromosomes would be 1/8.
In this case, the cells have three pairs of chromosomes. Then, the calculation to find the fraction would be: (1/2)^3= 1/8
