<span>A. Stimulus is the term used to describe what causes organisms to react to their environment. Stimulus is something that can provoke organisms to respond to the world around them. For example, if you put your hand on the stove, the stove is going to be the stimulus for you to get burned and move your hand from it because it will be to hot - that is going to be your reaction to the stimulus. Camouflage is a type of hiding mechanism, parasites are organisms, and homeostasis is equilibrium in an organism. </span>
An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.
A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.
A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

Complete question is:
Which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?
a) Replacement of a polar amino acid with a nonpolar amino acid at the protein's outer surface
b) Replacement of a polar amino acid with another polar amino acid at the protein's surface
c) Replacement of a polar amino acid with another polar amino acid in the protein's interior
d) Replacement of a polar amino acid with a nonpolar amino acid in the protein's interior
I wanna say it’s b but if not I’m so sorry !
Answer:
Reproductive cells are called: Gametes.
Female Reproductive cells: Egg.
Male reproductive cells: Sperm.
Explanation:
In sexual reproduction each sex has 2 reproductive cells, the egg and the sperm. Sperm fertilizes the egg and the egg will now grow into an embryo. As a whole those two cells are called gametes but depending on gender they have different names.
Answer:
The correct answer is option D) six dominant and two recessive.
Explanation:
The most common genetic inheritance pattern involves cross between heterozygous recessive parents which means it has one allele of each character in every parent (suppose Tt).
Cross between these parents provide these offspring; TT, Tt, Tt, and tt which exhibit 3:1 ration which can also be mention as 6:2 which means 6 out of the 8 has dominant (homozygous or heterozygous) and 2 out of 8 offsprings are recessive alleles.
Thus, the correct answer is option D) six dominant and two recessive.
