Species A
description of the evolutionary relationships shown in
the model?
a. Species C has more DNA and protein sequences in
common with Species A than with Species B
Species
b. Species Chas more DNA and protein sequences in common with Species A than with Species B
C. Species B and Species A share the most recent common ancestor
d. Species A is more closely related to Species C than the Species B.

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
