Answer:
so here correct option is A. 5
Explanation:
solution
as number of population groups live in a definite area is called diversity
so here in 1 there is only 2 groups of population
and in 2 there is 3 types of population groups
and in 3 there is 2 type of population groups
and in 4 there is 4 type population group
but they are not not evenly abundant and population of 1 group that is much less
so it might be a foreign population group
so here in 5 there is 4 type of population group which means it has higher diversity compare to other
so here correct option is A. 5
Answer:
D. We know more about the Cenozoic era because this the most recent time period in the history of the Earth, and we have more information available to study.
Explanation:
The Cenozoic era is the era that is by far the best studied and known by the scientists. The main reason for this is that this era is the most recent one, and it is actually the era we live in. Because it is the most recent era, the Cenozoic is abundant with lot of evidence of what has happened in it. The fossil records are very rich as the fossils didn't had that much time to totally decompose. The rock layers are much younger, so they contain much more detailed evidence of the plant life, climate, changes in the environment. The oceanic crust is also in abundance, which is not the case with the other eras as the oceanic crust is constantly suducted.

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.
