integumentery system
Explanation:
your skin is actually the first protection against illness-causing pathogens.
Answer: Genes are responsible for coding proteins, which are needed for all of our body functions and to build our body structures. So, a mutation could affect the way a protein is made. If the error occurs in the gamete cell, it could lead to a mutation in a growing fetus. Because all cells in the body form from two fertilized gametes, this mutation may exist in all the cells of the developing baby. If it occurs in another cell, a skin cell, for example, then the mutation would be confined to the cells in the skin tone.
The question is incomplete as it does not have the options which are:
A. Merocrine gland
B. Apocrine gland
C. Salivary gland
D. Holocrine gland
Answer:
D. Holocrine gland
Explanation:
Exocrine glands are the organs or the subcellular structures which secrete a substance which is excreted out of the body.
The exocrine glands are different from the endocrine glands as their secreted products are released out of the body which is not in the case of endocrine glands.
The wax is secreted by the sebaceous glands by the production of cells that break along the base of the garland with substance into the ductal system by the exocrine glands called Holocrine glands.
Thus, Option-D is the correct answer.
Holocrine glands will release whole broken open cells into their ductal system. These cells contain the stores of substance to be released by the gland. This method of secretion requires frequent cell turnover and replacement.
Answer: B.
Explanation: Cytosis in this context is the taking in, and releasing of various nutrients, proteins, toxins, etc. in and out of the cell. This is facilitated by the plasma membrane because it's our wall that surrounds the cell deciding who goes in and who goes out.
