It is the option C, meiosis occurs in stem cells and its end result is to form two daughter cells identical to the stem cell, which contain the same ADN. This is divided into Meiosis Stage 1 and 2, in the first form two identical cells and in the second form four haploid cells with half the stem cell ADN

Answer:
The correct answer will be option-C.
Explanation:
Light-dependent reactions are the reaction of photosynthesis which takes place in the presence of light.
During light reaction, ATP and NADPH intermediates are produced which are utilized during the light-independent reaction. The main reactions that take place during light reactions are photolysis of water and ATP synthesis due to the electron transport chain.
Electron transport chain generates electrochemical gradient across the thylakoid membrane sue to the accumulation of protons in the thylakoid lumen and fewer protons in the stroma of the chloroplast.
This causes the osmotic movement of protons down their concentration gradient through ATP synthase. The movement if hydrogen ions take place from thylakoid lumen to stroma forming ATP molecules.
Thus, Option-C is the correct answer.
Answer:
Explanation:
It is important that a cell undergoes replication before cell division occurs because, the main goal of cell division is to make more cells. And for all these cells to remain functional, all their components must be intact and complete. without this, these cells might not function. Thus, the goal of replication is to produce the next new copy that would go into one of the daughter cells produced. With DNA replication, the set of DNA present in a cell can be duplicated and then each daughter cell that results from division can have its own entire set of DNA and then cell division can theoretically continue as normal indefinitely.
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
