Answer:
DNA replication is a process where the DNA is copied and replicates to produce the 2 identical copies of the molecule. Strands of DNA molecule work as a template for the production of complementary strands. The DNA splits synthesizing a fork. A new DNA is always synthesized in a 5' prime to 3' prime manner. Replication of both the DNA strands goes in two different ways.
1) Leading strands: It is a strand which is goes to the direction same as the replication fork movement and synthesized in 5'-3' prime direction. This strand formation is occurred as nucleotides are continuously added to the 3' prime end after polymerase reads the DNA template (original).
2) Lagging strands: It is a strand which is goes to the opposite direction as the replication fork movement and synthesized in 3'-5' prime direction. It is synthesized in fragments which are known as okazaki fragments. Lagging strand synthesis needs RNA primase.
Therefore, primary consumers get about 10% of the energy produced by autotrophs, while secondary consumers get 1% and tertiary consumers get 0.1%. This means the top consumer of a food chain receives the least energy, as a lot of the food chain's energy has been lost between trophic levels.

Answer:
B. the direction of the wind at the time it was deposited
Explanation:
Cross beds refers to those rock beds which are formed due to the deposition of bed forms such as dunes. These cross beds are the group of inclined layer which is formed due to the flowing of water or wind. These rock beds represents the movement or direction of wind and water at the time of deposition and as a result cross beds are formed. So we can say that cross beds were formed due to the direction of wind.
