Answer:
The correct option is C: antigen-binding sites
Explanation:
The antibody is shaped much like the letter Y in the English alphabet. It has two antigen binding sites that are identical in nature. The specificity of these sites is determined by the amino acid sequence that makes it up. Antibodies are complementary to these antigen binding sites, and the antibodies have an incredible ability to recognize a great variety of antigens.

Explanation: there’s actually no similarity at all. A cell membrane is made of phospholipids, globular proteins, glycolipids, glycoproteins, and cholesterol, and has passages that serve explicitly for passive and active transport of materials through it.
The skin is made of cells and dead keratin and serves as much as possible to prevent most substances from moving through it. It’s “designed” for toughness and distensibility, not for selective permeability.
All in all, the difference is that a cell membrane is explicitly and only for the passing and transport of materials through it, and the skin in the skin is made to be tough and durable, almost the opposite of a cell membrane.
Answer:
4
Explanation:
Cytokinesis is the process by which the cytoplasm splits, forming two daughter cells from one parental cell. It occurs towards the end of mitosis, after the DNA has been replicated. The process of mitosis generates a cell with two nuclei, and cytokinesis ensures that each daughter cell receives one nucleus.
Without the process of cytokinesis, the physical process of the production of two cells from one parental cell would not occur, so the cell would not divide into two daughter cells.
