Answer:
D. 4E-BP1 binding to elF4E prevents loading of the mRNA onto the ribosome.
Explanation
In eukaryotic organisms, the eIF4E translation initiation factor functions by directing the ribosomes to the 5'-terminal cap structure of the messenger RNA (mRNA) in order to start the translation. Moreover, phosphorylation is a posttranslational modification of specific amino acids on proteins that play diverse cellular functions by altering protein stability, location, and/or enzymatic activity. It has been shown that elF4E phosphorylation is increased in response to cellular stimuli that induce translation in the ribosomes (e.g., growth factors, hormones, etc). The eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) is a repressor of mRNA translation which is phosphorylated and inactivated by growth factors and hormones, thereby inhibiting 4E-BP1 binding to elF4E and consequently activating translation.

Explanation:
Animals that live in temperate woodlands, the Arctic, tundras, and other forest animals such as wolves,, bears, and chipmunks have large amounts of fur and store large amounts of body fur for hibernation purposes.
The correct answer is the amygdala.
The fear response begins in the brain and scatters all through the body to make amendments for the flight reaction or best defense. The response of fear initiates in the part of the brain known as the amygdala. It is the almond-shaped arrangement of nuclei in the temporal lobe of the brain and is involved in determining the emotional silence of the stimuli.
For example, the amygdala gets stimulated whenever one witnesses a human face with an emotion. This response is more noticeable with fear and anger. A threat sign, like the sight of a predator, initiates a fear reaction in the amygdala that stimulates the regions taking part in preparation for motor activities taking part in flight or fight.
