Answer:
Your answer is A). True.
Explanation:
The integumentary system is made up of several organs and structures including the skin, hair, nails, glands, and nerves. The primary function of the integumentary system is to protect the inside of the body from elements in the environment, like bacteria, pollution, and UV rays from the sun.
Answer:
Cell walls prevent cells from dying in hypertonic conditions.
Explanation:
The cell wall is a rigid structure, essential for the survival of fungi, and knowledge of its composition may be useful for the development of new antifungal drugs. This wall does not alter the characteristics of the fungus, it stimulates and presses the fungus to flourish.
The fungal cell walls are similar in function to the cell walls of many protists, bacteria and plants. They prevent cells from bursting in hypotonic environments, but are unable to prevent cells from dying in hypertonic conditions. These cell walls also provide the cell with a degree of physical environmental protection and differ in the molecular composition of plant cell walls, as the fungal cell walls are chitin, while the plant cell walls are formed by cellulose.
