Sometimes, pregnant women are very emotional. This is believed to be caused by extra estrogen and progesterone that are released
Strike441 [17]

Activational effect is the correct answer.

Activational effect is an impermanent hormonal effect that leads to a change in physiological activity or behavior in both humans and adult animals. For instance, when testosterone levels rise in male songbirds they become more aggressive and tend to engage in courtship behavior. Also, a pregnant woman may get more emotional than usual due to an extra level of progesterone and estrogen during pregnancy.

Opossums are solitary animals that usually meet in nature only to mate. What is their probable distribution pattern?
Goryan [66]

Random distribution is the probable distribution pattern of opossums.

Explanation:

The opossums are the member of low density population. They are sparsely distributed because of the low number. There are troubles for them to find a mate.

Their habitat makes them solitary as they have flexible dietary habits. they are terrestrial animals living in burrows and are nocturnal.

They have random distribution pattern. The opossums are distributed in the population as random. The mates in opossums do not have choices of mates and the environment conditions in which they live are stagnant.(having no social life). Random interaction is seen in <em>species which do not have any social  bonding</em> between the species of the animals or plants.
