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.

You’ve likely heard of polar bears (Ursus maritimus) and grizzly bears (Ursus arctos horribilis). Have you heard of a grolar bea

Karolina [17]

Answer:

allopatric speciation.

Explanation:

When the population belonging to the same biological species becomes separated from each other due to some geographical factor such that no gene flow can occur between the two separated populations then the speciation that occurs on account of this is known as allopatric speciation.
The geographical isolation that separates the two groups can be the origin of a mountain, the formation of islands, volcanic eruption, etc. which prevents the two groups fro mating with each other and ultimately causes their lineage to speciate.
Although the two separate populations are unable to mate due to geographical factors, if the two populations are allowed to mate again, given that they have not been separated very long ago, they can give rise to hybrids.
Thus, in the given question it is given that polar bears and grizzly bears have been mated and hybrids have been produced and this points out to the fact that polar bears are result of allopatric speciation.
