Answer: REM

Explanation:

There are four stages, 3 of them are non-REM stages, (or NREM) and obviously, the other is the REM stage.

We are looking for a stage where your body becomes "paralyzed".

This would be the REM sleep stage.

This is the stage where most of your dreams happen, and that is why your body is more-or-less paralyzed, so you do not move while dreaming.

There are other characteristics, like irregular (and faster) breathing and an increase in blood pressure and heart rate.

Is it easy for breeders to produce mutants?
Eva8 [605]
It depends! If we're talking about something like a cute little Matlipoo, your answer is yes. These are technically considered mutants as they posses characteristics that are not found in either of the original populations (Maltese + Poodles). Not all mutations are bad. Those who survived the bubonic plague are said to have a mutated gene that enabled them to be more resilient against the illness. 

In the case of inbreeding the mutation can prevent offspring from being born by either causing sterility in the parents, or it will cause a miscarriage so the fetus is terminated naturally in the beginning. Sometimes the offspring is still born (deceased at birth), or has debilitating symptoms like in cerebral palsy. So there is a chance that the offspring may never be born, making it impossible for a breeder.

Mutations can also be spontaneous, so a breeder might mean well by selecting two animals from different family trees, but both of the parents could produce mutant offspring together.

This question is pretty vague, you should ask your teacher for clarification.

In some cases, a hormone is unable to have its effect unless the target cell has a simultaneous exposure to a second hormone. Wh
postnew [5]

Answer:

The correct answer is option D. Permissive.

Explanation:

The permissive effect or interaction of a hormone is in which hormone can not show or exert its complete effect without the presence of another hormone on a specific target site or cell.

The interaction of a hormone can occur in two more ways - synergies and antagonism where synergy occurs when two hormones perform the same action on a target cell and impact are amplified, and antagonist has the opposite role in the presence of another hormone.

Thus, the correct answer is - d. Permissive.
