Answer:
Ecology.
Explanation:
It's the study of the interaction between organisms with eachother and their environment.
Ans.
An electron carrier is defined as a molecule, which is capable of receiving one or more electrons from an electron donating molecule (electron donor). In given figure, molecule NADP (nicotinamide adenine dinucleotide phosphate) is acting as an electron carrier that accepts electrons form chlorophylls and form NADPH.
Thus, the correct answer is 'option C). NADP.'
Answer:
The fork is drawn to emphasize its similarity to the bacterial replication fork depicted in Figure. Although both forks use the same basic components, the mammalian fork differs in at least two important respects.
First, it uses two different DNA polymerases on the lagging strand.
Second, the mammalian DNA primase is a subunit of one of the lagging-strand DNA polymerases, DNA polymerase α, while that of bacteria is associated with a DNA helicase in the primosome. The polymerase α (with its associated primase) begins chains with RNA, extends them with DNA, and then hands the chains over to the second polymerase (δ), which elongates them. It is not known why eucaryotic DNA replication requires two different polymerases on the lagging strand. The major mammalian DNA helicase seems to be based on a ring formed from six different Mcm proteins; this ring may move along the leading strand, rather than along the lagging-strand template shown here.

This statement is true.
Some scientist refer to the adrenal medulla as a 'misplaced' sympathetic ganglion because <span>embryologically, they arise from the same tissue. As the name itself says, the adrenal medulla is located within the adrenal gland, and represents its central part. </span>
