The answer would be B made of one cell.
C I know this is hard but it’s easy
Gene interaction is the determination of a single trait or phenotype by genes at more than one locus; the effect of one gene on a particular trait depends on the effects of a different gene located else where in the genome. One type of gene is epistasis. One of the difference between the epistatic gene and hypostatic gene is that the alleles at the epistatic gene mask or repress the effects of alleles at another gene. Hypostatic gene on the other hand is the whose alleles are masked or repressed.
The best way to keep track of experiments and other scientific data would be to write it in a data table. Hope this helps!
Your bronchioles are some of the smallest airways in your lungs. Inhaled air passes through tiny ducts from the bronchioles into elastic air sacs (alveoli). The alveoli are surrounded by the alveolar-capillary membrane, which normally prevents liquid in the capillaries from entering the air sacs.
