Answer:
<h2>(A) Protein x normally stimulates cell division.</h2><h2 />
Explanation:
Protein who stimulates cell division are known as proto-oncogenes. If there is a mutation in proto-oncogene ,then this gene is converted into oncogene which causes cancer. Here protein x ( proto-oncogenes) normally stimulates cell division, if new mutation occurs in this gene, then this gene is converted into oncogene and resulted in the formation of cancer.
The correct answer is letter B, it creates water reserves. When hydrological power is harnessed it is placed in dams, when these dams are filled, the water then flows into a mechanical turbine that is specific in converting water into mechanical energy. Water in these dams can later on be used for other purposes or for storing energy long-term.
