hope its help
Answer:People look at the fossil record and think the early history of many animals is filled with giants, but not for whales. It's only in recent geological times that whales have achieved really large sizes
It would require that the csf acts exclusively on : Myeloblasts
myeloblasts is a unipotent stem cell, which differentiate into one of the effectors of the granulocyte series.
It is commonly found in bone marrow.
In the light dependent reactions light energy is absorbed by the photosytem II and an electron is released. This electron causes a process called photolysis to occur(H20-->2H++2e-+1/2O2). This is how O2 is released in the atmosphere. The electrons resulted from photolyisis enter the electron transport chain. In the electron transport chain using the energy in the elecrtons, hydrogen protons are pumped inside the thylakoid. Those protons accumulate to form an electrochemical gradient. That means the protons need to flow out, and they do through an enzyme called ATP-synthase which turns ADP and inorganic phosphate into ATP and water. In the electron transport chain, the electrons reach Photosystem I where NADP+ is reduced and becomes NADPH.
ATP and NADPH store the energy absorbed in the light dependent reactions. Those two molecules are needed when CO2 is fixated in Calvin's cycle to synthesize glucose.
