Second, I'm sure biologists have a passing knowledge of some mathematics.
And others get Ph.D.s in mathematics. Most mathematics departments have a Math Bio group.

Further, even if biologists can't do math, does it mean they can't do biology? Does a lack of mathematical ability mean creationism is correct? They are different topics.

Trendy pseudo-scientific ad hoc garbage. They're desperately trying to mathematically model biological phenomena, most often with little success.

Further, even if biologists can't do math, does it mean they can't do biology?

It means biology is a soft science that should not be taken seriously. If you don't understand mathematics than whatever you understand is only at the level of theology anyway.
