Answer:
The correct answer is C. NADP⁺
Explanation:
NADP+ is the coenzyme that acts as the electron carrier during the photosynthetic process. The electron that is released from the splitting of water pass through the electron transport chain and at the end of the chain the electron is received by an electron carrier called NADP+.
So this passing of electron causes the transport of H ions in the thylakoid lumen from the stroma and when these ions come back through ATP synthase it forms ATP. Then these NADPH and ATP are used in the Calvin cycle to fix the CO2 into complex form. Therefore the correct answer is C. NADP⁺.
The complete period of non division during the cell cycle is G0 (Gap zero).
Yes your answer to this question is B. So you are correct.
Answer:
The correct answer is " two cardiac muscle cells are connected by gap junctions".
Explanation:
Intercalated discs are microscopic features seen in the microscope as cardiac fibers, found between the myocardial cells of the heart. These features correspond of two cardiac muscle cells connected by gap junctions. The intercalated discs allow the interconnection of multiple cardiac cell muscles to work simultaneously as a single functional organ or syncytium.
The right answer is Nutrients and water.
All unicellular organisms such as bacteria and fungi need water, a source of energy, a source of carbon, a source of nitrogen and mineral elements. These basic needs are sufficient to allow the nutrition of bacteria qualified as prototrophs. Some bacteria called auxotrophs require, in addition to basic needs, the presence of growth factors.
