It could either be A or D
I believe the purpose of the horns in the monsters is to make them look scary for work and thus appear charming to the monster sexes. Assuming that the monsters mate sexually, the selection of the horn numbers will depend on the whether more numbers of it make one look beautiful or whether it incurs any work related advantage. A small monster colony has a large amount of monsters that have an abnormal amount of horns. This indicates that the abnormal number of horns are preferred over fewer horns as they carry a certain advantage of having a scarier look.
Answer:
CO₂, also known as carbon dioxide
Explanation:
In the alveoli, oxygen enters the bloodstream, and carbon dioxide exits, the latter to be exhaled from the lungs.
Answer:
Genetic variation mechanisms are different in prokaryotes and eukaryotes, Transformation, transduction, and conjugation in prokaryotes whereas crossing over, random assortment, and random fertilization in eukaryotes.
Prokaryotes:
Prokaryotic cells can lead to genetic variation by recombining their genetic material. In prokaryotes, horizontal gene transfer (HGT), in which gene transfer from one organism to another in the same generation. The three most common ways of HGT are transformation, conjugation, and transduction.
Eukaryotes:
Eukaryotic organisms can perform either sexual and asexual or both reproduction in which they are able to transfer genetic material (DNA) to their offsprings. Such transfer of genetic material process is called vertical gene transfer. In sexually reproducing organisms, independent assortment during zygote formation, a mutation in genes, and crossing over during prophase 1 in meiosis is the process that increases the chances of genetic variation.
The "mechanism" is that the chromatids are being separated to show that they are being divided to later be divided in telophase
