Answer:
The correct answer is B. the two strands of DNA must separate.
Explanation:
DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.
The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.
After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.

<span>The migration routes of Homo sapiens reveal
that they went through many environmental and physical challenges but adapted
everything much quickly in comparison to the other animals. The evolution
allowed other species also to adopt these changes but it took them a long time
to fit in the new environment, a sub species of a species adopted the new and
the previous one could not, but Homo sapiens invented ways and tools to combat
and evolve much quickly. It included their living, dietary needs, clothing and
much more.</span>
Our central nervous system is made up of two tissues: the gray matter and the white matter. The gray matter is composed of the dendrites and the axon terminals where synapses are. These synapses are the links between neurons that transmits electrochemical signals. The white matter, on the other hand, is composed of axons that connect all the gray matter together. Therefore, the answer is: <span>white matter is primarily in the CNS in the presence of myelinated axons</span>
Answer:
Three Reasons
Explanation:
1, due to the genome. By birth, there is a biologically higher percentage of body fat in women.
2, unemployment. As normally in a South African household, it is the man that goes out to work while the women stay at home. loss of mobility means the accumulation of fats.
3, Males' major sex hormone is testosterone, and females have high levels of estrogen and progesterone in their blood. Females build up fat more easily than males.
