Is needed to keep most plants alive
Answer:
The <em>tetrad</em> occurs during the first phase of meiosis. It is the foursome of <em>chromatids</em> that forms when replicated homologous chromosomes align. It must be formed for crossing over to occur. It is broken apart when the homologous chromosomes separate in meiosis I.
Answer:
C
Explanation:
C is the most similar because unlike viruses, living things grow and develop, have a basic structure that IS based on cells, and don't require a host. So the only option here that is true for both living beings and viruses is that they both have a way to reproduce.
The fossilized fish which is found has jaws but no true bones belonging at point B on the Cladogram. Thus, the correct option is B.
<h3>What is Cladogram?</h3>
A cladogram may be defined as a phylogenetic tree that is based on the classification of evolutionary relationships.
In the given cladogram, D is any ancestral point from which speciation occurs. Point C is a basal taxon while A and B are sister taxons.
The organisms of point B have only jaws bu,t not true bones, while the organisms at point A have both jaws and true bones.
Therefore, it is well described above.

True, because the fossils of animals that ,for example, are similar to humans show us the different stages that the species went through, what it looked like, and gives us a good idea of how similar it was becoming to us.
