Hormones bring about their characteristic effects by altering target cell activity. true or false

The statement is true

Explanation:

The function of different hormones is to control the activity of levels of target tissues or cells.

To achieve this, hormones may

- ALTER the permeability of target cells

- activate some other cellular mechanism like enzyme synthesis in target cells; the formation of second messengers e.g cAMP, cGMP, prostaglandins etc to exert their function within the cells when direct entry is not possible

So, the statement is true.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
