Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
- <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing
</em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>

Answer:
The correct answer would be - Cells begin dividing faster, leading to cancer.
Explanation:
In the process of the cell cycle, there are several checkpoints that ensures that the cell is all set to move to next phase, the cell that not match the requirements cell have not move to next phase.
These checkpoints control the rate of cell proliferation or division and if a dividing cell fails to pass through any checkpoints due to the mutation, it is most likely divide uncontrollably and lead to cancerous or tumor cell.
Thus, the correct answer is - Cells begin dividing faster, leading to cancer.
