The correct answer for this question is A. Law of segregation.
All individuals have two alleles for a given trait. According to Mendel's Law of segregation, these alleles are passed down one each from both mother and father.
Explanations;
According to this law of segregation the allele pairs separate or segregate during the formation of gamete, during the process of meiosis, leaving each cell with a single allele for each trait, and randomly unite during fertilization. One pair of allele comes from the mother while the other pair comes from the father, and joins together to form a diploid cell. Therefore, organisms inherit two alleles for each trait one from each parent.
I think it is A to, since the tissues are the closet thing to cell, which microscopic anatomy studies.
The best response is this: USE A MOISTURIZER ON THE SKIN DAILY TO HELP REDUCE ITCHING.
Using a moisturizer on the skin is an effective mean of reliving dryness and in extension reducing itchiness. The moisturizer will keep the skin moist and thus reduce pruritus.
