<span>Cell membranes protect the cells that is why they are called the gatekeepers of the cell. A cell membrane can be internal or external like that of the case of eukaryotic cells with internal cell membrane. It is mostly made up of glycerophospholipids. This compound like other lipids is also soluble in water however, their unique geometry allows them to aggregate into bilayers without too much energy input. Cholesterol can also be found in the cell membranes however, it is not as abundant as the glycerophospholipids.</span>
Answer:
2 offspring will have the genotype Bb.
Explanation:
Crossing the genotypes Bb and Bb results in 2, or 50% of the offspring having the genotype Bb. In the top right box, the B on the top and the B on the side make the BB genotype. In the top left box, B and b make the first Bb genotype. The lower right box crosses B and b to make the second Bb genotype. The last box in the bottom right crosses b and b, resulting in the genotype bb. So, after crossing the genotypes written on the top and side of the punnet square, 2 of the offspring will have the Bb genotype. (I got this by combining the letters outside the punnet square in the box where the row and column meet) .
