A population of squirrels is preyed on by small hawks at maturity. the smaller adult squirrels can escape into burrows. the larger adult squirrels can fight off the hawks. after several generations, the squirrels in the area tend to be very small or very large. this is an example of disruptive selection. In disruptive selection, the extreme traits i.e., very small and very large sizes are favoured over intermediate trait i.e., average size.
This suggests that the body cavity (coelum) evolved before the lophophore. Protostomes are one of the groups of animals having a true body cavity and are believed to share a common ancestor. They include annelids, mollusks, and arthropods. Lophophore is an organ characteristic of aquatic invertebrates (protostomes) that functions in filter feeding, it consists of a ridge of hollow tentacles bearing cilia, which waft food particles into the mouth.<span />
Answer:
the maximum number of species that can live in an ecosystem.
Explanation:
The correct choice in this problem is that carrying capacity is the maximum number of species that can live in an ecosystem.
- An ecosystem provides resources for organisms contained within it.
- The maximum number of organisms that an ecosystem can successfully support is the carrying capacity.
- Several factors can determined the carriage of an ecosystem.
- It could be space, resources, mating partners, nutrients etc.
All organisms share a common ancester: humans share a common ancestor with E. coli; E. coli share a common ancestor with an oak tree; humans share a common ancestor with an oak tree.
<span>If I hypothesized the two organisms shared a recent common ancestor, they I would predict that their genomes would be highly similar. For example, their genomes would contain about the same number of bases, and the base sequences (especially of protein-coding genes) would be highly identical.</span>
