The monomers, or small units, used in the synthesis of DNA molecules are called

disaccharides
amino acids
nitrogenous bases
nucleotides

Answers

Answer:

D. nucleotides

Explanation:

The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.

D. Nucleotides.

Nucleotides are the name given to DNA's monomers. A backbone is formed by the sugar and phosphate down either side of the double helix.

What is the synthesis of DNA?

These nucleotide units bind together to produce DNA, which can happen naturally or artificially (in vitro) (in vivo). A nitrogenous base (cytosine, guanine, adenine, or thymine), pentose sugar (deoxyribose), and phosphate group make up a nucleotide unit.

DNA replication is the process through which new DNA strands are created in living cells.

All living cells in the natural world synthesize DNA molecules through the process of DNA replication. This frequently happens during cell division. DNA replication happens so that each daughter cell has a precise copy during cell division.

Explanation:

as levels of CO2 in the blood begins to rise,the body can respond through hypoventilation or hyperventilation respectively

As degrees of CO2 in the blood begin to upward push, the body can reply through hyperventilation or hypoventilation, respectively. The CO2 is sure to hemoglobin paperwork a carbamino compound. In circumstances in which the CO2 and H+ concentrations are excessive, the affinity of hemoglobin for O2 is reduced.

How does the frame adjust the quantity of carbon dioxide within the blood?

The blood consists of carbon dioxide to the lungs, where it's miles exhaled. As carbon dioxide accumulates in the blood, the pH of the blood decreases (acidity will increase). The mind regulates the quantity of carbon dioxide that is exhaled by controlling the rate and depth of respiration (airflow).

How does the frame alter blood oxygen ranges?

defenses that the virus must bypass in order to infect a body cell. (5 points)

Answers

Answer:

The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body. The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs. 

The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera. Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.

The antiviral defense is composed of changes in cells that prevent viral replication and increase susceptibility to death by lymphocytes.

What innate defense mechanism against viruses?

Viral replication interferes with protein synthesis and cell function and leads to injury and death of the infected cell. The main mechanisms of innate immunity against viruses are inhibition of type I interferon infection and NK cell-mediated destruction of infected cells.

With this information, we can conclude that the antiviral defense is composed of alterations in the cells that prevent viral replication and increase the susceptibility to death by lymphocytes, thus eliminating the reservoirs of viral infection.
