Answer:
Dark colour occurs.
Explanation:
The amino acid changes in the MC1R protein may change the structure and function of the protein because the amino acids are the building blocks of proteins. This change in amino acid leads to increased production of eumelanin, which results in the dark color of the protein. So we can say that change in the amino acids leads to the change in the structure and function of MC1R protein.
Answer:
The correct answer would be - three chromosomes.
Explanation:
Meiosis is the type of cell division that takes place in only sex cells and called reduction division as a single parent cell divide into four daughter cell that contains a half number of chromosomes as the parent cell.
The daughter cells are always haploid and have the half number of chromosomes. If an organism has 2n number of in its parent sex cell the daughter cells after meiosis will have n number of chromosomes
Therefore, mosquito = 2n = 6
after meiosis = n = 6/2 = 3
Thus, the correct answer would be - 3 chromosomes.
The right answer to this question is option C. the traits acted upon natural selection were genes.
At the time Charles Darwin developed the evolution theory, there wasn't a single study about genes in all science scenery, that could be explained by the lack of technology to study them and even to know they existed in the first place.
So, his theory was basically talking about adaptation, if an organism can't survive a specific environment, he'll probably die until another generation comes in and this one can survive in this environment, passing their genes to the next ones. The lack of information was the knowledge about the genes we have today, that's why most scientists take only the new Darwin theory, that includes the study of genes.
Answer:
They hide in cool, shady, moist places under rocks and logs and in damp cellars.
Tiger salamanders can be difficult to spot because of their secretive nature and ability to spend long periods of time burrowed underground
They do not drink, but absorb water through the skin while sitting in puddles, in wet mud or sand, or by flattening their bodies on dew-covered rocks.
Tiger salamanders are wide spread but rarely seen because adults spend most of their lives underground.
They often occupy rodent, tortoise or crayfish holes, or burrow into soft dirt.

I hope these were enough :)
