Certain genes that allow for a certain thing to happen are turned on or turned off as needed. A brain cell may have the gene needed to send electrical pulses to other brain cells or other parts of the body, whereas a heart cell may have the genes that allow it to contract to pump blood. (I don't know if those are real genes, but hopefully you get the idea)
Answer: (c) It generates ATP, which cells can use to do work.
(d) It generates chemical gradients, which have potential energy.
Explanation:
The overall process of Cellular respiration is the aerobic break down of organic compounds (food) with the release of CO2, water and energy in form of ATP which drives most cellular work.
Organic compound + oxygen --------> carbon dioxide + water + energy (ATP + heat)
In cellular respiration during the break down of food in glycolysis and the citric acid cycle, chemical energy (NADH and FADH) are extracted from each cellular process and transported to the electron transport chain built in the inner mitochondrial membrane. The chemical energy harvested from food is transformed into a proton-motive force, a gradient of H+ across the membrane. When this H+ election fall from their gradient via ATP synthase, Chemiosmosis couples this proton motive force to phosphorylate ADP to form ATP.
Hello!
The answer is:
A mutation is a malfunction in the bodies DNA. Mutations are caused by either an error in the DNA stream, or self harming habits, like smoking, can cause mutations.
I hope this helped, and have a blessed day! ♥~
Answer:
100%
Explanation:
Assuming the gene for polydactyly is represented by P. Normal finger will be represented by p.
A woman that is homozygous for polydactyly trait will have genotype PP while a man with normal 5 fingers and toes will have the genotype pp (since P is dominant over p).
PP x pp = Pp, Pp, Pp and Pp.
All the offspring will have the genotype Pp and since P is dominant over p, it means all the offspring will have polydactyly trait.
<em>Hence, the percentage of the offspring of the couple that would be expected to be polydactyly is 100%</em>
