He is correct, the correct answer is
B. club mosses, horsetails, and ferns.
The answer is; Biodiversity resulting from few ancestors
Adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. The parts of the population in the different ecologies begin to adapt to their local environments. Due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. They, therefore, diverge to different species sharing a common ancestor.
The aorta carries oxygenated blood from the right ventricle to the rest of the body for energy and metabolism.
Answer:
Explanation:
The tar located in the La Brea tar pits is today a fossil fuel that began its formation many hundreds of millions of years ago from the bodies of marine organisms. During the last ice age that ended a few tens of thousands of years ago, some animals got trapped in the tar and left their bones behind. They are not something that created it but only got trapped in preexisting tar.
The molecular data are not found here but rabbits and whales are linked with the dogs and pigs in a cladogram due to evolutionary relationships.
<h3>What is a cladogram?</h3>
A cladogram is a graphical representation used to evidence the relationships between organisms due to a common evolutionary origin.
A cladogram is composed of a root that represents the common ancestor of the group and nodes where taxonomic groups diverge.
Cladograms based on molecular data use the homology level of nucleotide sequences of the genome to determine evolutionary relationships among individuals of different species.
In conclusion, rabbits and whales are linked with dogs and pigs in a cladogram due to evolutionary relationships.
