Answer:

If you jump up and down on Earth, what happens? You go right back down. If the gravitational force wasn't going down, we wouldn't even be able to stand on Earth without floating away.

Which environmental factor could lead to a decrease in genetic variation in a population of tuna?
jeyben [28]

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>

zvonat [6]

Answer:

Yes, it is.

Explanation:

Penguins are a species of seabird that lives in the southern hemisphere, in areas close to Antarctica, characterized by its cold and wide expanses of sea without land. In this context, penguins are capable of living in these temperatures and feeding on fish and other marine elements. In addition, they are unable to fly, but not so to move through the sea using their wings for it.
