1. C
2.C
Explanation:
I've seen these questions before on a test from my school
<span>This
type of symbiosis is commensalism. Commensalism is a relationship between two
organisms in which one benefits from the other and the other organism is not affected
in any way. From the question above, in the relationship, microscopic mites are
the commensals as they benefit from their host; humans and humans neither benefit
nor are harmed.</span>
It will be able to target specific cells that need to be killed such as pathogens and not kill the entire organism.
Answer:
The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called <em>phylogenetic tree</em>
Explanation:
The phylogenetic tree is composed of,
• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
• Root → This is the older common ancestor that all lineages share. The first one in the tree.
Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
• Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.
• Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.
• Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.
