Answer:
Letter C
Explanation:
Salmon have a physiological adaptation that allows osmoregulation to occur in two different environments (seawater and freshwater). There are specific molecules in the salmon gills that "pump" and "remove" Na and Cl ions. When at sea these molecules pump the ions out of the salmon's body and into freshwater, the same molecules remove Na and Cl from the water bringing it into the animal's blood.
Answer:
chromosomes
Explanation:
Thread-like structures that are found in the nucleus of a cell that contains all DNA. Each chromosome is made of protein and a single molecule of DNA. Human cell nucleus contains 46 chromosomes or 23 pairs. Half of these chromosomes come from one parent and half come from the other parent.
Answer:
In species with polyploid, there are more chromosomal sets than in diploid one. Becouse there are more chromosomal structures available, events like mutation, recombination, DNA lose, are more probable to occur.
As the generations pass, the accumulation of these changes tend polyploid to speciation.

Answer:
8-kb
Explanation:
As you can see in the picture attached, the cutting sites are consecutively situated in the genome. For that reason, if the largest fragment results when A and B cut, and the cutting site of C is betwen A and B, then the fragment expected from a digest with A and C could be calculated as follows:
