The correct answer is: DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication
DNA polymerase is an enzyme that synthesizes DNA during the DNA replication by adds nucleotides to the 3’ end of a primer. This means that the new chain is formed in a 5’ → 3’ direction.
Because double-stranded DNA is antiparallel, DNA polymerase moves in opposite directions on the two strands-leading and lagging strand.
The leading strand is copied continuously since DNA polymerase is moving towards the replication fork. The lagging strand is copied discontinuous. DNA polymerase is moving away from the replication fork (and helicase that separates the strands), so it must constantly return to copy newly separated stretches of DNA. So, the lagging strand is copied as a series of short fragments-Okazaki fragments that are joined together by a combination of DNA pol I and DNA ligase.
Answer:
Natural selection
Explanation:
According to Darwin's theory, natural selection is the process by which individuals better adapted to their environments have more chances to survive and reproduce, and thereby their descendants will be better represented in the next generation. This mechanism exploits the existence of natural variation among members in the population which is used to select those individuals that are better adapted (i.e., with a higher adaptive fitness) for their environments. Natural selection is a key mechanism of evolution by which species change across time.

Answer is the first choice - form non-metals</span>. Some acid and metal reactions don't form anything especially with weak acids. But many acids react with metals to form salt and hydrogen, which are considered non-metals.
