Answer:
True
Explanation:
Evolution is the change in the characteristics of a population over generations. This is caused by nature selecting out some disadvantageous traits and preserving advantageous traits over successive generations through natural selection pressures. In this case, the white moth is at a disadvantage in the environment compared to the black moth. The allele for white color is, therefore, ‘weeded out’ over time.
Proteins are made on small organelles, called ribosomes, in the cytoplasm. The genetic code is transferred to the ribosomes by a small molecule called messenger RNA (mRNA). A protein is made in the following way: The gene unzips, mRNA bases pair with DNA bases forming a strand of mRNA.

Answer:
d. carries nerve impulses toward another neuron, a muscle fiber, or a gland cell
Explanation:
An axon is a fiber of the nerves that transmits nerve impulses( electrical signals) away from a cell body and towards another neuron, muscle fiber or gland cell.
We have two types of axons in the body.
a. Myelinated axons
b. Unmyelinated axons.
The difference between Myelinated axons and Unmyelinated axons is that the Myelinated axons has an external covering or insulation which is called the myelin sheath.
The myelinated axons are very numerous and mush faster than the unmyelinated axon.
