The process of choosing only plants and animals with desirable characteristics to reproduce
Answer:
retrograde axoplasmic transport
Explanation:
The retrograde axoplasmic transport is a type of fast axonal transport that moves the substances at a fast rate by using proteins. These proteins transport the substances along the surfaces of the microtubules of the cytoskeleton of nerve cells. The retrograde axoplasmic transport moves the substances towards the soma or cell body from the terminal ends of the axon. This type of axonal transport mostly moves the substances that are to be recycled or broken down.

Internal and external factors regulate cell division
Explanation:
Internally, hormones act as cell signals to regulate cell division. Thyroid hormone, for example, plays a role in regulating cell growth and division in the body. When the hormone is produced in higher concentrations by thyroid glands, it spurs cell division and vice versa.
External factors include aspects like nutrition. If the cell is able to gather enough nutrition from its environment, then it is capable of carrying out several cycles of cell division. However, when resources are limited, cell division is limited to a few cycles. This is why denying babies good nutrition during their early childhood results in stunted growth.

The right option is; c. Both A (judgment) and B (inhibitions)
The first area of the brain affected by alcohol is the area that controls judgment and inhibitions. The first area of the brain to be affected by alcohol is the cerebral cortex, followed by hippocampus, cerebellum, frontal lobe, medulla and the reticular activating system. The cerebral cortex is responsible for intellectual functions of the brain such as judgment, thinking, inhibitions, reasoning, organizing, voluntary movement, and total behavior.
