Which of the following is needed in the process of DNA replication?

1 answer:

4 0

All of the above are needed. Nucleotides are the basic building blocks of new DNA, ATP energy is needed because replication is an active process, and enzymes catalyze the reactions needed to carry it out (e.g. helicase to separate the strands to be replicated, DNA polymerase to build the new strands, and ligase to "glue" the fragments together).

what does the increase in incidents of polar bears visiting human settlements indicate

snow_lady [41]

The correct answer is "limited prey is driving the bears to seek food in human settlements".
Due to the warming of the Arctic waters, the ice is melting, resulting in a serious decline of floating winter ice. Polar bears need these floating parts of ice to hunt, therefore this new situation limits the hunting opportunities of the bears. That is why polar bears are driven to human settlements to look for food.

timofeeve [1]

Answer: B. Random mating

Random mating can be define as the individuals of one sex are potentially be the partners of the members of the opposite sex. It is also called as panmixia. Here, the chances of getting mates is certain. It occurs in large population. The physical and geographical barriers can prevent the random mating. In this allelic frequencies will not vary if the mating is conducted in a single population.
