Answer:
from the axon hillock toward the axon terminals.
Explanation:
Axon hillock is a cone-shaped elevation of an axon. It is the region where axons join the cell body. In most neurons, nerve impulses arise at the junction of the axon hillock and the initial segment of axons. This region is called the trigger zone. From this region, a nerve impulse travels towards axon terminals. Axon terminals may have synaptic end bulbs at their tips. As nerve impulse travel from axon hillock to the axon terminal, synaptic vesicles having neurotransmitters are released into the synaptic cleft.
Answer:
The animal triglycerides have a higher proportion of saturated fatty acids than the plant triglycerides.
Explanation:
The triglycerides have three fatty acids attached to the single glycerol molecule by ester linkage. The fatty acids may be saturated or unsaturated. The triglycerides with saturated fatty acids such as the animal triglycerides exhibit a relatively tight packing of these fatty acids and make them solid at room temperature.
On the other hand, the triglycerides with unsaturated fatty acids such as the plant triglycerides are liquid at room temperature since the presence of double bonds in the hydrocarbon chains leads to weaker interactions and does not allow the tight packing of the fatty acids.
Answer:
1/2
Explanation:
The allele for the red-green color blindness is X-linked recessive. The father of the woman was colorblind (X^cY) which means that the woman is a carrier for the allele and has genotype (X^cX). The genotype of the colorblind male would be X^cY. A cross between a carrier woman and a color-blind man would produce progeny in following ratio= 1/2 colorblind daughter: 1/2 normal daughter: 1/2 colorblind son: 1/2 normal son.
Therefore, there is a 50% probability that their first son is colorblind.
