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>
The answer is; C
A wetland in an area in the environment that is regularly or constantly inundated with water either from precipitation or due to proximity to riverbeds. Other than watersheds, other wetlands include marshlands, mangroves, lakes, rivers, and etc.
Answer:
The world climate would drastically change.
Explanation:
- First off, both poles would have rapid expansion, with the freezing of more water near the poles.
- Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.
- Deserts would expand and the average temperature would rise.
- Also, many animals would also die out, because of the change in their environments.
- Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.
