Explanation:

A more formal definition of homeostasis is a characteristic of a system that regulates its internal environment and tends to maintain a stable, relatively constant condition of properties. The normal value of a physiological variable is called its set point.

Answer:

refer to a pulmonologist for polysomnography evaluation

Explanation:

Based on the information provided within the question it can be said that the next step in managing this child's condition is to refer to a pulmonologist for polysomnography evaluation. This is because the child has a high potential for having sleep apnea since the parents are reporting that the child snores and has frequent throat infections and he does not have a high enough number of GABHS throat infections to warrant tonsillectomy.

<h2>Baroreceptors </h2>

Explanation:

Baroreceptors are splash type nerve endings in the walls of veins and the heart that are invigorated by without a doubt the degree of, and changes in, blood vessel pressure. They are amazingly rich in the mass of the bifurcation of the inner carotid corridors (carotid sinus) and in the mass of the aortic curve. The essential site of end of baroreceptor afferent strands is the NTS.
The capacity of the baroreceptors is to keep up foundational circulatory strain at a moderately steady level, particularly during an adjustment in body position. Flawless baroreceptors are very viable in keeping quick changes in pulse from minute to minute or hour to hour, but since of their versatility to delayed changes of circulatory strain (> 2 or 3 days), the framework is unequipped for long term regulation of blood vessel pressure.

Can anyone tell me the ratio of the genotype and phenotype ???

iogann1982 [59]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2><h2>_____________________________________</h2><h2>Phenotype:</h2>

It is the physical appearance of the trait, whether the person has smooth chin or cleft chin.

<h2>Genotype:</h2>

A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or hom.ozygous, recessive or dominant.

<h2>_____________________________________</h2><h2>Alleles:</h2>

Cleft chin C is dominant over smooth chin c

<h2>Genotypes of Parents:</h2><h3>FATHER:</h3>

Father has smooth chin thus, it is hom.ozygous recessive i.e. cc

<h3>MOTHER:</h3>

Mother has cleft chin, since cleft chin is dominant there are two possibilities of her genotype,

Heterozygous Dominant : Cc

Hom.zygous Dominant : CC

but if we cross the hom.zygous fominant mother to hom.ozygous recessive father we will get all the offsprings with the same genotype phenotype so it is not possibile, So the mother is HETEROZYGOUS DOMINANT Cc

<h2>_____________________________________</h2><h2><u>Question</u>:</h2><h2>_____________________________________</h2><h2>Genotypes of Parents:</h2>

FATHER: cc (Hom.ozygous Recessive)

MOTHER: Cc (Heterozygous Dominant)

<h2>_____________________________________</h2><h2>Punnet Square:</h2>

Picture attached!

Picture no 1: it is the cross between hom.ozygous recessive father and hom.ozygous dominant mother and all the offsprings are same both phenotypic and genotypic way so IT IS NOT POSSIBILE

Picture no 2: Its cross between hom.ozygous recessive father and heterozygous dominant mother and there are hybrid and pure recessive both type of offsprings present thus IT IS POSSIBLE!

<h2>_____________________________________</h2><h2>Genotype Ratio of the Offspring:</h2>

Hybrid : Pure Recessive

2 : 2 or 1 : 1

<h2>_____________________________________</h2><h2>Phenotype Ratio of the Offspring:</h2>

Cleft Chin : Smooth Chin

2 : 2 or 1 : 1
