You are performing experiments on viruses. You have a variety of enzymes in your lab that target different organelles or macro-m
klemol [59]

Answer:

B. nuclease (destroys DNA and RNA)

Explanation:

Viruses are the particles that contain a protein coat called the capsid. Inside the capsid, viruses have their genetic material. Viruses may have single-stranded or double-stranded DNA molecules or single-stranded or double-stranded RNA molecules as their genetic material. Therefore, to destroy viruses, one must target their genetic material. Nucleases are enzymes that digest nucleic acids (DNA and RNA). The use of nucleases would destroy the genetic material of viruses and would be most effective to control them.

Which describes the partial pressures of systemic cells under resting conditions?
Irina18 [472]

The conditions which describe the partial pressures of systemic cells under resting conditions are:

  • Relatively constant partial pressure of gases
  • PCO₂ of 45mm Hg, and
  • PO₂ of 40mm Hg

<h3>What are systemic cells?</h3>

Systemic cells are cells of the body which receive oxygen from the capillaries during respiration and gaseous exchange.

The systemic cells receive oxygen-laden blood from the capillaries and transfer carbon dioxide into the blood capillaries.

The conditions which describe the partial pressures of gases of systemic cells under resting conditions are as follows:

  • Relatively constant partial pressure of gases
  • Partial pressure of carbon dioxide, PCO₂ of 45mm Hg, and
  • Partial pressure of oxygen, PO₂ of 40mm Hg

In conclusion, the partial pressure of the gases in systemic cells under resting conditions are fairly constant.

*Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body..

*DNA occurs in a circular form* in bacteria only..

* Ribosomes size in bacteria 70s and in human body 80s

*Capable of growth at temperatures greater than 80 C only in bacteria
