<em>crossing-over affect evolution...
<u>reason:
</u>during crossing-over chromosomes exchange their genetic information...
because of this variations occur in new generation,, in new generation some characters are from maternal chromosomes and some are from paternal chromosomes... </em>

Answer:
b. axons
Explanation:
The Peripheral Nervous System consists of nerves and ganglia. Nerves are nothing more than bundles of parallelly arranged nerve fibers surrounded by connective tissue. Each of these fibers is formed by an axon and the sheaths surrounding it. The ganglia, in turn, are accumulations of neurons, which usually form spherical structures, are located outside the central nervous system and are also linked by axons bridges.
The answer is C. Enzymes lower activation energy, allowing the reaction to happen more quickly, which is why they are called catalysts.
Heterozygous parents would have the genotype Rr. In a punnett square, this would show a result of 25% homozygous dominant (RR) offspring, 25% homozygous recessive (rr) offspring, and 50% heterozygous (Rr) offspring.
(I attempted to simulate a punnett square with the text)
