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>
<span>The answer is reflection. Objects that do not produce their own light, reflect light when the light is shone on them. This is because the light bounces off them by reflection. One example is the reflection of sunlight by the moon so it is visible in the night. </span>
Answer:
Viruses are not made up of cells. They are made up of a set of genes within a caspid, a protective shell
Explanation:
The answer would be: <span>secondary aging.</span>
There is two type of aging, primary and secondary aging. Primary aging is the one that happens because of the age so it can't be prevented. Secondary aging happens because of bad diet and disease, so it can be prevented by doing healthy lifestyle or medicine.
