Answer:
<u>Option-(C,A):</u>Archaea must undergo meiosis prior to cell division, and Each chromosome in a polyploid organism has distinct genetic information.
Explanation:
- <u> Archaea are polyploid:</u>
Archea are prehistoric organisms who can be also termed as the prokaryotic living cells, as they developed from a less developed form to a more complex shape or system. As the feature of being a polyploid makes it easy for any archea to survive in the most severe conditions. As the polyploids contain a number of genetic materials in pair, as each pair is very distinctive in features or more independent in regulating a function then the other. Giving it a more diversity of genetic sequence its genome.
Along, with that the process of meiosis occurs prior to the process or event of cell division. Which is for production of the copies of the parent cell, which posses the same genetic material as that of the parent cells.
The genetic variations seen in and between populations are known as human genetic variation.
Humans differ genetically from one another. Due to developmental mutations and gene copy-number variation, even monozygotic twins, who arise from a single zygote, may differ genetically. Techniques like genetic fingerprinting rely on individual differences, even between closely related people.
There are 324 million identified variations from sequenced human genomes as of 2017.
A person's genome typically differs from the reference genome by 20 million base pairs, or 0.6% of the total 3.2 billion base pairs, as of 2015.
In contrast to other species, humans are genetically uniform. While a limited number of genetic variations are found more commonly in particular geographic regions or in individuals with ancestry from those places, this variance accounts for the majority of genetic variation.
Genetic variation between populations occurs for at least three reasons. If an allele offers a competitive advantage, natural selection may endow people with an adaptive advantage in a particular environment.

The main reason is because they are heavy, and because they don't have to chase their food. They're not predators and their shells give them protection like running away gives protection to other herbivores.

"Matter is recycled, but energy is not. In an ecosystem, matter is represented by the presence of biogeochemical elements such as Hydrogen, Carbon, Nitrogen, Oxygen, Phosphorus and Sulfur."
