Scientists have suggested that these examples of gigantism are possible because of the extreme cold found in these waters.
Answer:
Evolution, mutation, and adaptation
Explanation:
Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.
Answer:
BECAUSE THEY FEED OFF OF OTHER ORGANISMS
Explanation:
In a newly fertilized egg, the vitelline layer lifts away from the egg and hardens to form a fertilization envelope.
Therefore, the correct answer is Option A.
<h3>What is vitelline layer?</h3>
- Vitelline layer or vitelline membrane (VM) is a structure that surrounds the outer surface of the plasma membrane of an egg or ovum. In some organisms (e.g.: birds), the vitelline layer surrounds the extracellular yolk and the ovum.
- It is multilayered and functions to protect and give shape to the egg yolk and separate it from the egg white.
- VM consists of protein fibers and protein receptors necessary for sperm binding.
- As its function is to provide support and protection to the yolk, after fertilization, the vitelline layer gets hardened and separated from the yolk to form fertilization envelope.
