I think it's c because when you move farther away from a sound it's less intense.

Lunna [17]

Visual information from the retina is relayed through the lateral geniculate nucleus of the thalamus to the primary visual cortex — a thin sheet of tissue (less than one-tenth of an inch thick), a bit larger than a half-dollar, which is located in the occipital lobe in the back of the brain.

Select the accurate statement(s) regarding the divisions of the nervous system.

rodikova [14]

The given question is incomplete as there is an option twice and other options are not provided. however, the complete option for the question is as follow:

a) the sympathetic division tends to arouse the body for action.

b) the visceral motor division(ANS) carries signals to glands, skeletal muscle, and smooth muscle.

c) the somatic motor division carries signals to the somas of the neurons.

d) the parasympathetic division tends to have a calming effect.

e) the CNS has both a sensory and motor division.

Answer:

The correct statements are -

a) the sympathetic division tends to arouse the body for action.

d) the parasympathetic division tends to have a calming effect.

Explanation:

The sympathetic division regulates organs and glands during crises. It helps the body in crisis to act on the basis of fight or flight. For instance, it builds the pulse and the progression of blood supply to the legs, so you can flee from risk.

The parasympathetic sensory system is liable for the body's rest and processing reaction when the body is loose, resting, or taking care of. It essentially fixes the work does by sympathetic division after an unpleasant circumstance.

Thus, the correct statements are -

a) the sympathetic division tends to arouse the body for action.

d) the parasympathetic division tends to have a calming effect.

Suppose that a gene for coat color in mice has two alleles, B and b, where B is completely dominant and encodes a black coat col

pogonyaev

Answer:

Genotype= Bb

Phenotype= Black coat

Explanation:

A single gene coding for coat color in mice is involved here. An allele is a contrasting or variant form of a gene. Most genes possess two alleles.

According to Mendel's findings in his law of dominance, an allele is capable of masking the expression of another gene. The allele masking or being expressed is called a DOMINANT allele while the allele being masked is called a RECESSIVE allele.

The alleles of a particular gene can either be in a homozygous or heterozygous state. The alleles are homozygous when they are the same in that gene while it is heterozygous when they contain two different alleles i.e. a combination of the dominant and recessive allele.

In this case of a gene coding for coat color in mice, The allele coding for Black coat (B) is dominant over that coding for brown coat (b). This means that in an heterozygous state, allele B will mask the expression of allele b.

The genotype of an organism is the actual genetic make-up of that organism while its phenotype is just its phyaically expressed trait.

Since a heterozygous organism has a combination of two different alleles, hence, the mouse in an heterozygous state for coat color will have a Bb genotype.

Also, since the allele for black coat coloration (B) is dominant over the brown coat coloration (b), thus, in a heterozygous state, the black colour allele will mask the expression of the brown color allele, and express itself (exercise its dominance).

Therefore, a Bb genotypic mouse will produce a black coat phenotype.

N.B: A recessive trait can only be expressed when the organism is homozygous recessive for a particular gene i.e. have the same recessive genes but a dominant phenotype can have a homozygous or heterozygous genotype.
