Answer:

Receiving sensory information and carrying commands to the muscles.

Explanation:

The spinal cord serves as the transmission conduit for the passage of action potential as sensory information through the sensory/afferent neurons to the dorsal roots of the spinal cord.The information synapse with the inter neurons,branching off to the brain and emerged as the response through the motor/efferent neurons to the effectors(muscles).

This pathways is called reflex arc. Thus most of the involuntary action of the body is conducted through the spinal cord

In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cro

Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)

During a drought on the galapagos islands, finches with larger beaks were able to crack the large tough seeds produced by plants

TEA [102]

It is an example of directional selection.

The different kinds of natural selection can influence the distribution of phenotypes within a population. In stabilizing selection, an average phenotype is preferred.

In directional selection, a modification in the surrounding changes the spectrum of the observed phenotypes, and in diversifying selection the extreme values for a trait are preferred over the transitional values. This kind of selection usually pushes speciation.

The directional selection, in the field of population genetics, refers to a mode of natural selection in which an extreme phenotype is preferred over other phenotypes, making the allele frequency to change with time in the orientation of that phenotype.

Who is most likely to experience nasal regurgitation?

leonid [27]

The answer is young child.

Nasal regurgitation it's when the food regurgitates out of the nose.
This is more likely to occur in babies/ young children with some birth defects in the soft palate, or if they have a cleft lip. Those birth defects, usually, get fixed with surgery when they are still children, that's why is less frequent after that age.
