Answer:
The inactivation of one protein that slow down the cell cycle could lead to cancer. (option b).
Explanation:
The cell cycle is the process a cell undergoes when it divides during its life. This process includes a control mechanism to prevent normal cells from replicating more than normal, called cell cycle regulation.
In oncogenesis - the formation of malignant tumours - many factors induce the abnormal growth of a tissue by the abnormal multiplication of the cells that form it, leading to cancer. One of these factors may be a mutation in the DNA that prevents the production of regulatory proteins.
The mutation that produces exaggerated cell growth -and which can eventually lead to cancer- can create defects in a specific regulatory protein that slow down the cell cycle, so that exaggerated and uncontrolled cell replication occurs.
Once a tumor tissue has formed, successive mutations will lead to a lack of cell differentiation, the property of forming blood vessels, the ability to invade tissue and lose its apoptosis mechanism, that characterizes cancer cells.

Answer: Option C) Reduction is the gain of electrons.
Explanation:
Reduction is a process involving a gain of electron(s), while oxidation involves a loss of electron(s).
Thus, an oxidizing agent is a substance that accepts electron(s) and become reduced, while a reducing agent is a substance that donates electron(s) and so becomes oxidized.
Thus, reduction is the gain of electron(s)

Answer: The correct answer is peripheral
Explanation:
The Peripheral nervous system consists of the following:
- sensory neurons, which leads all parts of the body to the central nervous system
- motor neurons that runs the central nervous system to all parts of the body.
Thus, Peripheral nervous system is the answer
Im not really sure , but it might have something to do with polar chemical compound <span />
