Answer:
The. Two populations of sculpin lived on Lake Baikal, but a genetic change in one of the populations prevented them from crossing, thus creating a new species of sculpin.
B. The additional information I would use to test the hypotheses would be: 1) is there any species of fish similar to sculpin in the same lake? 2) what is the genetic change presented by the sculpins?
Explanation:
My hypothesis about sculpin fish states that sympathetic speciation has occurred. This speciation occurs when two populations of the same species can no longer promote crossings between them, thus creating an evolutionary process, which results in the creation of two distinct species, in the same habitat. I believe that this type of speciation is more common to happen in aquatic environments and in fish, since these environments present less physical barriers than the terrestrial environment. This usually occurs with the existence of genetic modifications within one of the populations. As a result, to test my hypothesis, I would need information about the existence of species similar to sculpin within the same lake, in addition to knowing what genetic differences between them would promote this type of speciation.
Answer:
The correct answer is - ENDOPLASMIC RETICULUM
Explanation:
In the cell, all cell organelle performs a specific function. Protein synthesizes with the help of ribosomes then they are sent to the endoplasmic reticulum for folding the proteins to their correct form or shape before sending them to the Golgi body for packaging.
Protein folding is an important function performed by the ER and must be correctly folded into particular 3-D shapes in order to function correctly and if not correctly folded then degraded by lysosomes.
