7 0

Answer:

23 chromosome pairs.

Explanation:

In humans, the DNA strands are packaged in a tightly coiled 1400 nm structure called the chromosomes. Since each cell contains the DNA therefore each cell contains the chromosomes.

The human genome is packaged into 46 linear chromosomes but since the humans are diploid organisms, therefore, the chromosomes form pairs with the homologous chromosomes and form 23 pairs of chromosomes. Every cell of humans possesses 23 pairs of chromosomes.

Thus, 23 pair of chromosomes is correct.

Which pair is incorrectly matching polymer-monomer? nucleic acids - nucleotides proteins - amino acids lipids - monosaccharides
Andrew [12]

The pair that incorrectly matches polymer-monomer is lipids-monosaccharides (option C).

<h3>What is a monomer?</h3>

A monomer is a small molecule which can be covalently bonded to other monomers to form a polymer.

A polymer, on the other hand, is a large molecule made up of a chain of many monomeric units, formed by chemically bonding together.

The following are the monomer-polymer combination we have in nature;

  • Carbohydrates - simple sugar/monosaccharide
  • Protein - amino acid
  • Lipids - fatty acid
  • Nucleic acid - nucleotide

Therefore, the pair that incorrectly matches polymer-monomer is lipids-monosaccharides.

<h3>What is retroviral therapy? </h3>

Retroviral therapy is an HIV treatment where medicines are taken as prescribed by a healthcare professional. This treatment reduces the amount of HIV in an HIV-infected person.

HIV does not have a cure but antiretroviral therapy can reduce the risk of potential health issues caused by HIV.

This treatment can help to control the virus in an HIV-infected person within 6 months. The treatment for HIV cannot prevent the transmission of other sexually transmitted diseases.

Therefore the correct option is D.
