Answer:
For black:
For brown:
For golden:
Explanation:
This question explains the phenomenon of epistasis. Epistasis encompasses the concept where one gene is dominant in such a way that it completely masks the effect of any other gene present. Here, black is said to be the epistatic gene considering the abundance in its appearance. The ratio of 9:3:4 can be seen in cross 8 which makes this question an example of recessive epistasis. Recessive epistasis occurs when alleles of one locus mask the appearance of alleles, both dominant and recessive, on the other locus. Recessive epistasis is also known as supplementary epistasis.

Answer:
The difference between pinocytosis and receptor-mediated endocytosis is that <u>pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis offers more selectivity.</u>
Explanation:
Pinocytosis and receptor-mediated endocytosis are two types of endocytosis.
The first one consists of plasmatic membrane invaginations that capture extracellular fluid with different nutrients and sends it to the inside of the cell in vesicles. The second one, receptor-mediated endocytosis, consists of receptors on the outside of the plasmatic membrane and clathrin proteins on the interior side of the membrane. When the receptors are in contact with its specific molecule, a vesicle surrounded by clathrin proteins, is formed transporting specific molecules to the cell's interior.
Answer: His phenotype will be Bb. He will have brown hair because it is a dominant trait.
Explanation: Heterozygous indicates that there are two different genes present in a genotype (Bb instead of BB or bb).
Root hair cells absorb minerals and water from the soil.
The water absorbed by the root hair cells passes through the plant in xylem tubes, to then reach the leaves. The energy from the sun is then used to convert water(H2O) into hydrogen (H) and oxygen(O2).
