Explain why evolution is a unifying theme
Setler [38]
Unify means to make or become united uniform, or whole.

(I personally don't agree that evolution is true; but here is my answer)

Evolution is a way Scientists like to theorize the world was made/ created. They try to explain why everything can about in a uniform way. Everything has a reason or theory. Even though scientists haven't been able to prove that Evolution actually exists, many people like the idea of it- just for the reason that it gives a more believable whole approach to how the Earth and Universe came about. For some people, it is more uniform than a religion.

I hope this helped you!

bearhunter [10]

Answer:

The answer is 6.4 × 10^{-20} Joules

Explanation:

This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × 10^{-12} N

displacement = 8.0 nm = 8.0 × 10^{-9} N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × 10^{-12}  × 8.0 × 10^{-9} = 64 × 10^{-21}

= 6.4 × 10^{20} Joules (in standard form)
