The answer could be either B or D. Both are important for marine biology. I would have to say D is the best answer though!
Answer:
(B) Energy released from the chemical reaction is used to directly phosphorylate ADP.
(D) Energy released from the chemical reaction is used to directly reduce NAD+
Explanation:
phosphorylation is a addition of phosphoryl group to an organic compound.Substrate level phosphorylation is a process where there is ATP is produced from ADP by transferring a high energy phosphate group from phosphorylated metabolic compound.This process occurs in glycolysis and citric acid cycle.and this pathway is exergonic pathway
I believe it is behavioural isolation. When there are changes within a certain species, e.g. new birdcalls are formed in certain individuals in a species, "traditional" birds may not like such mating calls and only choose to mate with the more common birdcalls from majority of the birds. There are also some birds that may like the new birdcalls, and choose to mate with birds with those birdcalls. They become genetically isolated as they continue such behavior. Eventually, through genetic drift and other mutations, different species form from a single specie.
Hope this helps! :)
