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.

The major buffer in blood is composed of the weak acid carbonic acid (H2CO3) and its conjugate base, bicarbonate ion (HCO3 - ).

Answer:

The increase in the amount of carbon dioxide in in blood will lead to respiratory acidosis

Explanation:

Carbon dioxide in its normal level between 38 to 42 mm Hg plays vital roles in the human body like regulating the PH of the human blood, breathing regulation and other things. If the amount of carbon dioxide is high more than the range level, it will cause what is called respiratory acidosis.

Respiratory acidosis is a situation in cause by decrease in ventilation i.e Oxygen level leading to increase in carbon dioxide and drop in PH level of the blood.

Gonads are sex organs that produce gametes. Male gonads are the testes, which produce sperm and male sex hormones. Female gonads are the ovaries, which produce eggs (ova) and female sex hormones.

if a cell increases the activity of its actin severing proteins, will it lead in the short term to more or less actin polymer ma

marta [7]

More polymer will form if the concentration of free actin monomers is higher than the Cc at both the plus and minus ends.

Less polymer will form if the concentration of free actin monomers is lower than the Cc at both the plus and minus ends.

Actin polymerization encourages FAK and Src to activate small G proteins by signalling to GEFs and GTPases (e.g., Rho and Rac). The actomyosin network is then forced to develop as a result of G proteins' induction of cytoskeleton-regulating proteins.

What stops cells from forming actin polymers?

Actin monomer is sequestered by monomer-binding proteins, reducing its availability for polymerization. As a result, actin does not polymerize when monomer-binding proteins are present in stoichiometric levels.

Q. If a cell increases the activity of its actin severing proteins, will it lead in the short term to MORE or LESS actin polymer mass? Chose the most accurate answer.

Increased severing activity will result in LESS polymer under any conditions.

Increased severing activity will result in NO CHANGE in the total amount of polymer under any conditions. It simply results in a larger number of smaller filaments.

Increased severing activity will result in MORE polymer under any conditions.

If the concentration of free actin monomers is below the Cc for both the plus and minus ends, then MORE polymer will result. If the concentration of free actin monomers is above the Cc for both the plus and minus ends, then LESS polymer will result.

If the concentration of free actin monomers is above the Cc for both the plus and minus ends, then MORE polymer will result. If the concentration of free actin monomers is below the Cc for both the plus and minus ends, then LESS polymer will result.

Blood groups are a classic example of ______________ inheritance in humans?

Keith_Richards [23]

<span>There are multiple types of inheritance mechanisms in humans. The well-known ones are include autosomal dominant, where only one copy of the gene is enought for the individual to express that characteristic. Another type is autosomal recessive, in which an individual must receive a copy of the gene from both parents in order for the gene to be expressed. The type concerning blood groups is codominance and it is when two different versions of a gene are expressed. Both of the alleles have a role in the appearance of the characteristic. Both the A blood group and B blood groups are dominant; however, if both alleles are present, the individual has an AB blood group.</span><span />
