Answer:
Explanation:
RNA is single-stranded, not double-stranded: Unlike Dna polymerases, RNA polymerases are able to join RNA nucleotides together without requiring preexisting strand of RNA.
Organisms with hard parts such as a shell,or bones are much more likely to become fossilized than animals with soft parts like a worms.

Answer:
B.
artificial selection
Explanation:
Artificial selection is often utilized in crop and animal farming to obtain favorable traits in organisms. Organisms with desirable traits are selected and crossed with each other. Since the selection is done by humans and not by natural processes, it is called artificial selection.
In the given case, the farmers select corn plants with large ears. The selected plants are crossed with each other so that the next generation has the maximum chances of producing large ears. Hence, artificial selection is used here.
Answer:
Enzymes and substrates fit together like a lock and key since, in one enzymatic reaction, only the correct substrate (i.e., the key) binds to its corresponding enzyme (i.e. the lock).
Explanation:
An enzyme (or catalyst) is one protein that has catalytic functions, being therefore capable of accelerating chemical reactions. The enzymes are known to control the rate of these chemical reactions (i.e., catalysis) without suffering alterations during these processes. Thus, the enzymes are proteins that catalyze chemical reactions that are not favored under normal conditions. Moreover, one enzyme may catalyze more than one chemical transformation, as well as the same reaction may be catalyzed by two or more enzymes.
