Question: Which two statements are true for the leading strand in DNA?
It is synthesized toward the replication fork.
It is synthesized in the 3′ to 5′ direction.
It is synthesized away from the replication fork.
It is synthesized in the 5′ to 3′ direction.
Answer:
The two statements that are true for the leading strand in DNA are "it is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction"
Explanation:
Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA. The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.
A) This is predator-prey relationship.
B) Species A is prey and species B is predator.
- If prey population decreases in number, the predator population will also decrease because there is not enough food for predators to survive and vice versa.
- If predator population decreases, the prey population will increase because less prey will be eaten by predators and vice versa.
C) Let population A be Zebras, and population B Lions.
From the graph, at the beginning the there is increase in Lions, as well as in smaller rate in Zebras. At one point, the population of Lions begins to decrease, so they will eat less Zebras. This will allow Zebras to increase population. With more Zebras on the menu, more Lions will eat and increase their chance to survive. This leads to decrease in Zebra population. But again, with less Zebras, the Lion population must decrease allowing Zebra population to increase, and so on.
In the hydrologic cycle, after water precipitates to the surface, it can return to the atmosphere by processes of evaporation.
Answer:
Explanation:
Plants use carbon and release oxygen, and animals release carbon and use oxygen.
