Virus

Further Explanation:

AIDS (acquired immune deficiency syndrome) is caused by HIV (human immunodeficiency virus). The virus is a retrovirus that has a cone-shaped core that contains two copies of the single-stranded genome, reverse transcriptase enzyme, and core proteins. HIV infection weakens the immune response of the host body due to which the host becomes susceptible to secondary infections like fever, diarrhea, and cold. The infected person is at a higher risk of opportunistic pathogens. The population of T-helper cells declines during HIV infections. AIDS is the ultimate stage of HIV infection, where the host has a severely damaged immune system.

HIV infection is transmitted through body fluid (semen, vaginal fluid, breastfeeding, and blood) from an infected individual. The infection is spread through sex with multiple partners, sharing infected needles and syringes, and blood transfusion. The infection is not transmitted through insect bite, air, and water. The infected person may remain asymptomatic for a long time. The HIV infection can be diagnosed by ELISA (enzyme-linked immunosorbent assay) test.

After Frida stops exercising, she continues to breathe heavily. What is most likely occurring in her body?

Brilliant_brown [7]

Answer:

(D) Strenuous exercise has caused her body to be in oxygen debt, and she is breathing hard while lactate is transported to the liver. This is a result of anaerobic respiration.

Explanation:

As Frida was exercising, her muscle cells were undergoing a frantic pace of metabolism (contraction and relaxation), where oxygen supply did not supply the required effort, thus causing muscle fatigue and heavy breathing.

Physical activity is synonymous with moving muscles. The more muscle fibers strive to accomplish a task, the more they consume the oxygen brought into the bloodstream. When this occurs, the body begins to breathe hard as lactate is transported to the liver.

This forces the lungs to work at a fast pace, as they are responsible for oxygenation. The heart also speeds up because it needs to pump blood more vigorously. This is why during exercise the heart rate and breathing rate increase and we breathe heavily.

Prokaryotic DNA is enclosed within a nucleus, while eukaryotic DNA is not. O True O False

blagie [28]

Answer:

False

Explanation:

Prokaryotes do not have a nucleus.

This means their DNA is not enclosed in a nucleus and instead is in the cytoplasm.

On the other hand, eukaryotes have nuclei, so their DNA is enclosed within a nucleus.

So, this statement is false.
