Answer:

The correct option is <em>A. convergent evolution</em>

Explanation:

The phenomenon of evolution explains how different species might have common ancestors. This phenomenon explains that genetic variations might have led to the birth of different species from a common ancestor.

Convergent evolution can be described as a type of evolution in which similar features or traits can be observed in organisms although they may not have any genetic sequence in common. For example, sharks and dolphins look similar but they have huge differences in their genomes.

If there is a mutation in a zygote, where is it likely to be found in the fetus?
lisabon 2012 [21]
The correct answer is C.
The zygote is a single fertilized egg cell that the embryo develops from.
This one cell possesses one copy of DNA that is going to be passed to all other cells in the embryo because all other cells of the embryo develop through mitotic divisions of the zygote.
Therefore, if a mutation happens in the zygote DNA, all of the cells in the embryo are going to have it as well.

A bird is observed to nest along the coastline. It then spends hours out in the open ocean feeding on fish. What is this behavio
3241004551 [841]

Answer:

Nesting & Foraging behavior

Explanation:

Seabirds are generally tertiary consumers and / or marine predators that, in marine foodwebs, occupy the upper trophic level. They are very well adapted to all marine ecosystems and feed on a variety of prey: from micro-crustaceans to fish and cephalopods.

Generally, seabirds are observed performing a nesting behavior, by laying eggs near the shore, and then are found exhibiting foraging behavior -searching and foraging for prey- in both the coastline and pelagic zone, also known as the open sea.

Seabirds exhibit different foraging behaviors, for example, the <u>surface feeding behavior which involves flying along the surface with their beak  in the water. Gulls, albatrosses and petrels are examples of surface feeders.</u>

<u>On the other hand, plunge diving involves preying on fast marine organisms by diving into the water during their flight. Pelicans are example of seabirds who engage in this behavior.</u>
