Using the wordshaploid cell, diploid cell, and fertilization all together in a sentence - Fertilization is the union of two unicellular, haploid gametes to produce one unicellular, diploid zygote.
The process of combining the male gamete, or sperm, with the female gamete, or ovum. The product of fertilization is a cell called a zygote.

Cholesterol is the lipid that acts as a chemical messenger in the body, playing a role in cell signaling and hormone production. Therefore, the correct answer is option b.
Cholesterol is the lipid that acts as a chemical messenger. Cholesterol is a sterol, a type of lipid molecule, and it serves as a precursor for the synthesis of various important chemical messengers in the body, including hormones like testosterone and estrogen.
These hormones play key roles in various physiological processes, such as regulating the development and function of reproductive organs, and they act as signaling molecules that help coordinate different activities within the body. Cholesterol also plays a vital role in the structure and function of cell membranes.
The other options (adipose tissue and beeswax) are not typically considered chemical messengers in the same way that cholesterol and hormones are.
Therefore, the correct answer is option b.
