The peripheral nervous system is involved in both <u>voluntary and involuntary actions.</u>

Explanation:

The peripheral nervous system (PNS) is the neural system that resides outside the central nervous system (CNS). This contains nerves which in turn connect with the organs of the body like the sensory organs, glands, blood vessels, muscles etc with the central nervous system (CNS).

The PNS is divided into somatic and autonomic nervous systems.

The somatic nervous system contains sensory and motor nerve fibers which send sensory information and controls motor functions respectively. The voluntary movements of skin, skeletal muscles, bones, and joints are controlled by somatic PNS.

The autonomic nervous system composed of sympathetic, parasympathetic and enteric nervous systems controls the involuntary actions of smooth muscles of the internal visceral organs.

Why is a 50 percent recovery of single-crossover products the upper limit, even when crossing over always occurs between two lin

34kurt

Answer:

Because of homologous recombination

Explanation:

When genes are establish on different DNAs or far apart on the same chromosome, they are classified self-sufficiently and are said to be unlinked.

When genes are very close together on the same chromosome, they are said to be linked. That means that alleles, or genetic versions, that are already together on a chromosome will be inherited as a unit more often than not.

We can see if two genes are linked, and how closely, by using data from genetic crosses to calculate the frequency of recombination.

Using the technique of discovery recombination happenings for numerous gene pairs, we can make link maps that show the order and relative distances of the genes on the chromosome.

When the genes are on the same chromosome but far apart, they are classified independently due to crossing (homologous recombination). This is a procedure that happens at the start of meiosis, in which homologous DNAs randomly exchange matching fragments. Crossing be able to connection new alleles in combination on the same chromosome, causing them to enter the same gamete. When the genes are far apart, the crossing occurs with sufficient frequency for all types of gametes to occur with 25% percentage frequency.

When the genes are very close together on the same chromosome, the crossing still occurs, but the result (in terms of the types of gametes produced) is different. Instead of being classified independently, genes tend to "stay together" during meiosis. That is, alleles of genes that are already together on a chromosome will tend to pass as a unit to gametes. In this case, the genes are linked

Mycorrhizae is a mutualistic relationship between fungi and algae in which the algae takes advantage of the fungi.

SCORPION-xisa [38]

The answer to this question would be: False

The symbiotic between plant and fungus is called lichen. In this case, the Mycorrhizae having a mutualism symbiotic with algae as they are giving benefit to each other. The Mycorrhizae will give water and inorganic compound and the algae will give food. The answer is false because the algae are not parasitic to the fungi.
