Answer:
An increase of 3,500 J
Explanation:
Given that,
Energy added by swimmer = 12000 J
Heat removed by the surrounding = 8500 J
We need to find the total change in energy. It can be calculated using the law of conservation of energy such as :
As the change in energy is positive, it means that there is an increase of 3500 J.

Given enough time, these little changes can lead to those populations diverging into distinct species after so many successive generations. </span>
