Hiv is a retrovirus which contains rna as its genetic material. once hiv enters the body, it attaches to t cells that other lymphocytes respond to infection. gradually, hiv kills off most of the t cells. the rna is inside the capsule of the virus and is labeled

The correct answer is - A (labelled in attached diagram)

Explanation:

The HIV virus is a retrovirus that have RNA as genetic material that is present in the center in the capsule of the virus. HIV is a virus that kills the helper t-cells that are the immune cells of the body that activates other lymphocyte cells to act on infection.

Due to the killing most of the helper T cells the HIV affect the immune system of the infected individual.

Thus, the correct answer is - labelled as A in diagram attached below.

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
