Answer:

b. by increasing the heart rate

c. by increasing the respiratory rate

Explanation:

Increased activity of skeletal muscles would require an increased supply of oxygen to these cells to sustain the muscle contraction. Muscle cells perform aerobic cellular respiration in the presence of oxygen and produce ATP molecules to be used during muscle contraction. Therefore, there is an increase in heart rate to pump sufficient blood to the skeletal muscles which in turn ensures enough supply of oxygen. Also, there will be an increase in the respiration rate to inhale the required oxygen.

The surface area to volume ratio limits a cell

svetlana [45]

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

regulates blood volume and pressure, stimulates red blood cell formation, and controls fluid, electrolyte, and acid-base balance

omeli [17]

The Circulatory system regulates blood volume and pressure, stimulates red blood cell formation, and controls fluid, electrolyte, and acid-base balance.

What is Circulatory system?

To obtain oxygen into the blood, the circulatory system (cardiovascular system) pumps blood from the heart to the lungs. The remainder of the body receives oxygenated blood from the heart via arteries. Oxygen-depleted blood is returned to the heart by veins to restart circulation.

The human body is a tremendously intricate structure with numerous organ systems, including the brain, which regulates all bodily functions, lungs, which assist in gas exchange, and kidneys, which filter out waste products. However, the circulatory system controls all of these since blood is a fluid that keeps the body free of any materials that are not necessary for the body.

A strategy used by all microbes to help prevent denaturation of proteins during heat shock is:_______

Sauron [17]

A strategy used by all microbes to help prevent denaturation of proteins during heat shock is chaperone proteins.

What are microbes ?

Microbes are creatures that are too small to be seen without a microscope, such as bacteria, archaea, and single cell eukaryotes, which are nucleated cells like amoebas or parameciums. At times, we also refer to viruses as microorganisms.

In molecular biology, molecular chaperones are proteins that help big proteins or macromolecular protein complexes fold or unfold conformationally. There are different groups of molecular chaperones, all of which have the same purpose: to help big proteins fold properly during or after synthesis as well as following partial denaturation. Protein translocation for proteolysis involves chaperones as well.
