Usually the lava flows come towards the end of the eruption, once the magma has lost enough of its volatiles to flow more quietly. Cinder cone eruptions are comparatively short lived, and thus cinder cones are much smaller features than stratovolcanoes and shield volcanoes (usually no more than a mile at the base).
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 believe it is Translucent.
THE ANSWER WOULD BE A because homeostasis is about maintaining something so something doesnt shut down example maintaining body temperature.
