Answer: C. Chromosomes
When an egg and sperm cell
unite, fertilization follows. The chromosomes carry the genes that will be
transferred to the offspring. They have threadlike bodies that made up of DNA
and protein that carries hereditary information, which is used to help a cell
grow and reproduce.
Furthermore, humans have 46
chromosomes and 23 in each sex cell and they are found in the nucleus of a
cell.
Data have shown significant differences in nitrogen retention, blood cortisol concentrations, vital signs, water con- sumption, and urine production. Implications are that total energy balance is altered when an animal is exposed to ectoparasite infestations, thereby resulting in decreased productivity.
