kirza4 [7]

Answer:

Seafloor spreading at the mid-ocean ridge provides the mechanism for tectonic plate movement. The Earth's mantle moves through convection, showing that tectonic plates are able to glide. The location of the plates was determined by locating their boundaries, using data on the Earth's magnetic field.

Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to differ
Zepler [3.9K]

Answer:

Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.

Explanation:

Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.

In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.

Which listed transfusion reaction is most often associated with transfused patient's lacking iga?
IgorC [24]
The most common transfusion reaction, especially in patients lacking either IgA especially serum IgA, is the development of potentially severe hypersensitivity reactions or anaphylaxis. The most probable culprit is the presence of IgA in the transfused blood, because since the individual lacks IgA, then the IgA in the transfused blood is considered a foreign body triggering an allergic response.
