Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.
Answer:
The correct option is A. The lipids, because they are responsible for long-term energy storage.
Explanation:
The bodies of organisms are made up of different organic molecules known as biological macromolecules, each specialized to perform unique functions. For example, nucleotides are biological macromolecules made up of nucleotides. The function of nucleotides is to store the genetic information of an organism.
Lipids are macromolecules which are made from fatty acids and glycerol. The function of lipids is to store long- term energy for an organism. Hence, the biology student listed the wrong function for lipids.
The genetic change causes alterations in only one or a few nucleotide bases in known as mutation.
A mutation is a change in a brief section of a genome's nucleotide sequence. Another frequently replaces one nucleotide in point mutations; other changes involve the insertion or deletion of one or more nucleotides.
Errors in DNA replication or the harmful effects of mutagens, such as chemicals and radiation, which react with DNA and alter the architecture of individual nucleotides, are the leading causes of mutations.
DNA repair enzymes are present in all cells and work to reduce the frequency of mutations. These enzymes reduce genetic information loss, double-strand break formation, and DNA crosslinking by repairing DNA damage.

Answer:
CO2 levels will dramatically increase as well as food level supply will decrease. Oxygen levels will decrease too.
Explanation:
Plants take in CO2 and produce Oxygen. Without plants, they can't take in CO2, and it is a necessity for them to take it in. Plants would die. Food supply would decrease because plants produce glucose during photosynthesis. Glucose is a kind of natural sugar that will be lost. Plants produce fruits or vegetables, so if there are no plants then no food.
Hope this helps!
D. Bacteria because “bacteria” is actually a domain itself
