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>
I’m pretty sure it’s B. Relative saying
For mutations to affect an organism's descendants, they must: 1) occur in cells that produce the next generation, and 2) affect the hereditary material. Ultimately, the interplay between inherited mutations and environmental pressures generates diversity among species.
Answer:
Produce resistance variety or use of fungicides.
Explanation:
The best solution for the future is to produce resistance variety to Panama Disease or fungicide spray that kills Fusarium fungus that causes Panama Disease. If the variety is resistance against Fusarium fungus so they get no adverse affect from it. The use of chemical that kills Fusarium fungus is also a good method to protect banana industry from the adverse effect of this disease.
<span>Biome is the term for the physical amount of plant material at a location. But also it could be Biota. So It would better if you've attached any options to choose.</span>
