Answer:
b. enables cell to recognize and respond to external environment
Explanation:
There are two types of receptor present in/on the cell. The receptors that are present on the cell surface are called the cell surface receptor and the receptor which is present inside the cell is called an intracellular receptor.
The cell surface receptor is responsible for enabling the cell to recognize and respond to the external environment. The signal molecules that bind to the cell surface receptors are mostly hydrophilic and they generate an intracellular cascade in the cell which brings specific changes in the cell. So the right answer is b.
Answer: Metal
Explanation:
Metals do not degrade with time as they are not biodegradable in nature. They are not degraded easily by the effect of bacteria and natural forces.
The metals are not degraded by the bacteria so easily and it is found preserved for many years.
The body gets degraded easily by the effect of bacteria on it and will be rotten and degraded after sometime. This does not affects the metal so it will be preserved even after many years.
