Answer:
Explanation:
Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body.
Cancer is a mutation that occurs during the cell cycle, usually when it develops and grows it means the mutation was able to go through the cycle undetected at checkpoints so the cell was not destroyed by the lysosomes.
Answer:
A. The prism's index of refraction for violet light is greater than 1.35.
Explanation:
Answer:
40% is Adenine.
Explanation:
In DNA, Guanine pairs with Cytosine and Adenine pairs with Thymine.
If a strand of DNA contains 10% Guanine, that means that it also contains 10% Cytosine.
10% G + 10% C = 20%
100% - 20% = 80% (Adenine and Thymine)
80% ÷ 2 = 40%
The strand of DNA contains 10% Guanine, 10% Cytosine, 40% Adenine, and 40% Thymine.
Answer:
b. The daughter cells have the same number of chromosomes and the same amount of DNA.
Explanation:
Mitosis is the cell division that maintains the DNA amount and chromosome number in daughter cells. This is due to the fact that each mitosis is preceded by one round of DNA replication in S phase.
For example, if the parent cell had 2n DNA in 46 chromosomes, the daughter cells at the end of mitosis and cytokinesis would also have 2n DNA in 46 chromosomes.
