Explanation:
ANSWER: CANCER DEVELOPMENT
EXPLANATION:
Tumor suppressor genes (TSGs) are genes that regulates the cell cycle of a cell (i.e the cell division and replication). In other words, TSGs encodes protein that act as control or regulator of cell growth.
However, when there is an alteration in the genetic sequence (mutation) of the TSGs, this make the cell not to respond to cues that had been regulating it growth.
Thus, when cell growth is not regulated, it results to runaway or abnormal cell growth (i.e multiple folds cell division and replication), in other word referred to as “cancer”.

amphibians because it is a cold blooded vertebrate and has aquatic gill breathing larvea
Explanation:
Answer:
c. the plant root growing down into the soil
Explanation:
The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.
Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.
