Which of the following describes a genetic mutation that results in uncontrolled division of a single cell within the body?
Cancer
Gene therapy
Stem cell
Translation
The Correct Answer is A
A genetic mutation that results in the uncontrolled division of a single cell within the body describes cancer. Cancer is a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
The other options are not correct because they do not accurately describe a genetic mutation that results in the uncontrolled division of a single cell within the body. Gene therapy, stem cells, and translation are not processes that result in uncontrolled cell division.

Correct Answer is B
Explanation
A change that takes place as a solid turns to a liquid is that particles become less ordered. When a solid is heated, its particles gain energy and begin to vibrate more rapidly. As the temperature increases, the particles gain enough energy to overcome the forces holding them in place and begin to move more freely.This results in a loss of order as the solid melts and becomes a liquid.
The other options are not correct because they do not accurately describe a change that takes place as a solid turns to a liquid. Particles do not have a decrease in mobility, move closer together, or experience stronger intermolecular forces between them as a solid turns to a liquid.
