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.
Answer:
The correct answer is option B. maculae/ static equilibrium.
Explanation:
Maculae are mechanoreceptors present inside the saccule and utricle specialized for the static equilibrium detecting. Maculae use hair cells to find out the movements of the otolithic membrane occurs, which is the surrounding membrane of the macula.
The sense of the position of the head to determine the stability and posture is static equilibrium and it is determined by the maculae.
Thus, the correct answer is option- B. maculae/ static equilibrium.

Answer:
Boats must be cleaned after getting out of the water to ensure there arent any on the sides of the boat before entering another body of water.
Explanation:
The answer is: homologous; common; homoplastic.
<span>The bones in the wings of birds and bats are <u>homologous</u> because they derived from a <u>common</u> ancestor, while the wings are <u>homoplastic</u> traits. Homologous structures are similar structures shared by different groups and that are derived from a common ancestor. The similar anatomy of bones in the wings of birds and bats is inherited from a common ancestor of tetrapods (to which birds and bats belong). However, wings are not inherited from the common ancestor of birds and bats. Therefore, wins are homoplastic traits (analogous structures) because they have similar function but they are not inherited from the common ancentor.</span>
