Answer:
The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles
Explanation:
A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.
C. Insulating the body
Insulating the body is not a function of a protein.
Lipids are macromolecules which provide insulation.
<span>A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids. Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids. A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

Before a cell goes through cell division (mitosis), it must grow and make a copy of its DNA which is termed as an Inter-phase.
<u>Explanation:</u>
Some tasks must be carried out by the cells before they undergo division: The cell must grow, it must copy the genetic material (DNA) present in it, and divide into two daughter cells. These steps carried out by cells are termed as cell cycle.
Cells that contains a nucleus or Eukaryota cells, there are two major phases called interphase and the mitotic (M) phase. that comprises the cell cycle.
In inter-phase, growth of the cell and making a copy of its DNA is carried out.
In mitotic (M) phase, the cell separation of the DNA in the cell into two sets and division of its cytoplasm takes place resulting in the formation of two new cells.
Answer:
DNA and RNA are nucleic acids found in the cells of living organisms. DNA is a two-stranded molecule consisting of a deoxyribose sugar, while RNA is a single-stranded molecule with ribose as its sugar component. There are three primary types of RNA: messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA). Another kind of RNA is small nuclear RNA, or snRNA, which is involved in altering an RNA transcript.
Proteins are one of the vital biomolecules of life. These compounds perform a variety of essential processes to sustain an organism's survival, which include clotting of blood, transporting oxygen, contracting muscles and catalyzing chemical reactions. The building blocks of proteins are called amino acids.
The synthesis of proteins starts with transcribing the instructions in DNA into mRNA. The mRNA is then carried out of the cell's nucleus into the cytoplasm, specifically into structures called ribosomes. The ribosomes, which contain rRNA, are organelles where protein production occurs. The tRNA transports the amino acids to the ribosomes. The code sequence in mRNA is then translated, and specific proteins are synthesized by stringing amino acids together.
Explanation:
The molecule which is rich in nitrogen, soluble in water, lacks Phosphorous, and also contains hydrogen and oxygen in uneven ratios is amino acid.
