Agroup of students are reviewing material in preparation for a test on the male and female breasts. the students demonstrate understanding of the material when they identify which of the following?
a) striated muscle in the nipples contract causing them to become erect
b) the breast contain a limited upply of blood vessels
c) a primary function of the female breast is to produce milk
d) progesterone is primarily responsible for the growth of breath tissue.

Option (C).

Explanation:

Breast are the two prominences present on the upper region ventrally, present in the primates. These breast serve for the mammary gland. The estrogen and growth hormone causes breast development in females.

The primary function of the female breast is the production of milk by the process of lactation. These breast are used for feeding the young ones. The blood vessels are present in abundant supply in he breast.

Thus, the correct answer is option (C).

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
