F) chloroplast and cell wall
<span>The gene, is in fact the subunit of information on a chromosome, so this is a true statement. A chromosome is a structure that occurs within cells. It contains the cell's genetic material, which determines how an organism develops. For example, if we are talking about DNA, its molecule is a very long, coiled structure that contains many identifiable subunits known as genes.</span>
The effect of this mutation is a gain in function that will stimulate the sodium channel and allow more sodium to pass inside the cell.
There are two types of consequence of mutations on proteins, loss of function, gain of function or neutral.
Mutation gain of function (which is rare) is that the protein is gaining activity, this is the example shown with the sodium channel. This has negative consequences (toxic effect) if the protein works more than it should. This will affect the function of the cell and may destroy it. the rod cells are cells found at the level of the photoreceptor of the eye, this mutation can have serious consequences on the sight.
Answer:
Less
Explanation:
Hormones are chemical messengers produced by glands called Endocrine glands into the bloodstream in order to effect a change in a particular region of the body. Endocrine glands are those organs that secrete specific hormones e.g pancreas, pituitary gland etc.
When hormone concentrations are low in the blood, the gland will produce more amount of the hormone while the glands will produce lesser amount of hormone when there is a high concentration of hormones.
