The soft palate reflexively opens the nasopharynx to allow the passage of food, which is now called a bolus.
Gennadij [26K]
The answer is false. A bolus is the organization of a discrete measure of pharmaceutical, medication or another compound keeping in mind the end goal to bring its focus up in blood to a compelling level. The organization can be given by infusion: intravenously, intramuscularly, intrathecally, subcutaneously, and by inward breath. The article on courses of organization gives more data, as the first rundown of ROIs is not comprehensive.

There are many interconnections between the arterial branches of the coronary circulation, which function to maintain a constant
DaniilM [7]

Answer:

The correct answer is option-C

Explanation:

Anastosomes is a connection between the two interconnected tubular structures like in the loops of intestine or the blood vessels.

The anastomy between the blood vessels is known as the circulatory anastomosis. The connection is formed between the arteries and arteries or between veins and veins or between arteirs and veins.

The anastosome connections forms the bypass route for the flow of blood if one pathway of blood id blocked.

Thus, option-C is the correct answer.

Suppose a population is carrying a condition controlled by two alleles: R (dominant) and r (recessive). Only homozygous individu
White raven [17]

<span><u>The answer is A. 72.25 percent.</u>

The Hardy-Weinberg principle can be used:</span>

<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>

where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the frequencies of the genotypes.

<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15

To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85

Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the frequency of the RR genotype (p²):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.</span>
