Answer:
B) Polymerases can only synthesize in the 5' to 3' direction
Explanation:
The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
Answer: D
Explanation:One of the reasons for this is that there is little or no magma available at the plate boundary. The most common magmas at constructive plate margins are the iron/magnesium-rich magmas that produce basalts.

The correct answer of the given question above would be NUTRIENT-POOR SOIL. The characteristic about the Tundra biome listed below that does not contribute to a reduction of carbon dioxide on earth is the nutrient-poor soil. Other choices for this question include permafrost, carbon dioxide sink and <span>plants and their trapped carbon dioxide are frozen in the earth. </span>
