Question

Natural selection _____.

is random
favors organisms well adapted to the environment
cannot work if beneficial traits are not hereditary
is often called survival of the fittest

Which ones apply?

Answer 1

B and D are correct.

Answer 2

The second one and the last one are true; natural selection favours organisms well adapted to the environment, and is often called survival of the fittest.

Natural selection is not random, as evolution is not a random process.
Also, natural selection can occur even if the trait is not hereditary, as the process involves genetic mutations too.

So B and D.

Hope that helps!
