Answer: A. Environmental drivers plus genetic variation in the population result in natural selection
Explanation: over geological time environmental conditions change. Organisms do not survive in one environmental niche with traits adapted to a possible future change that might suit those traits. Adaptation is not a matter of choice: adapt if possible or go extinct.
There is a (badly named) concept called pre-adaptation, which is that variations in some existing trait render adaptation to a different environment more likely.
Because alpha ray can penatrate the body deeper than other x rays and do more damage
Continuous cell lines differ from primary cell lines in that <span>continuous cell lines are derived from primary cell lines.</span>
Explanation:
by carrying sediment from upper to lower layers.
Hello there buddy,
<span>RNA is able to hydrogen bond with water (otherwise it wouldn't be soluble), but since water is small and prefers to be able to move around freely, these hydrogen bonds are quite unstable. For that reason, RNA forms much more stable bonds with larger, compatible molecules. Among those, different RNA molecules may bind to DNA or proteins to serve some function, while they can also bind complementary strands of RNA.

I hope this helps you!
