Answer:

b. cause an increase in blood pH.

Explanation:

Carbonic anhydrases are zinc-containing enzymes that catalyze the reversible reaction of conversion between CO2 and bicarbonates (carbon dioxide hydration and bicarbonate dehydration). The conversion of bicarbonate to CO2 facilitates its entry into the cell. On the other hand, the conversion of CO2 to bicarbonate helps keep the CO2 inside the cell.

This enzyme is important in all living organisms for maintenance of acid-base balance (regulates pH ). For example, carbonic anhydrases lowers pH in the stomach by producing an acid.

Answer:

b. cause an increase in blood pH.

Explanation:

Carbonic anhydrase is an enzyme responsible for accelerating the conversion of carbon dioxide to carbonic acid, and is responsible for controlling blood pH. When this enzyme is inhibited by some molecule. In addition, inhibition of this enzyme reduces the amount of bicarbonate formed in the blood, since there will be no conversion of carbonic acid occurring at speed.

Type II topoisomerases display all of the following characteristics EXCEPT

Firlakuza [10]

Answer:

The correct answer is option A. "They only introduce supercoiling and cannot relax a covalently closed circular DNA".

Explanation:

Type II topoisomerases are enzymes that regulate the winding an unwinding of DNA during DNA replication. Basically, these enzymes are the scissor that remove the knots and tangles formed during the replication process. Is false to affirm that type II topoisomerases only introduce supercoiling and cannot relax a covalently closed circular DNA. Bacterial type II DNA topoisomerases work with the circular DNA of bacterium by changing the linking number of circular DNA by ±2.

In quiet breathing (A) inspiration is passive and expiration involves muscular contractions. (B) inspiration and expiration invo

Zolol [24]

Answer:

In quiet breathing inspiration involves muscular contractions and expiration is passive.

Explanation:

Respiration process involves two different stages, inspiration - inhalation- and expiration - exhalation-.

During inspiration, the diaphragm <u>contracts</u> and goes down, while intercostal muscles also <u>contract</u> and go up. These actions enhance the size of the thoracic box and <u>reduce internal pressure</u>. As a result, air flows in and fills the lungs.

During expiration, the <u>diaphragm relaxes</u> and the volume of the thoracic box diminishes, which causes the <u>pressure inside to increase</u>. In consequence, the lungs contract and the air is expulsed outside.

Which best describes how our understanding of DNA and inherited traits has changed over time

MAVERICK [17]

<h3><u>Answer;</u></h3>

It was developed by many scientists over many decades.

<h3><u> Explanation;</u></h3>

DNA is a type of nucleic acid that contains two long, twisted strands, known as double helix, that contain complementary genetic information.
A gene is a segment of DNA that is passed down from parents to children and confers a trait to the offspring.
The traits an organism displays are ultimately determined by the genes it inherited from its parents, known as genotype.
Our understanding of DNA and inherited traits has changed over time since it has been continuously developed by many scientists over may decades.
