Explanation: the seasons are caused by the tilt of the earth's rotational axis.
Answer:
The most appropriate answer would be C.electron carriers such as NADP⁺.
High energy electrons are transported through electron transport chain embedded in a thylakoid membrane in order to produce energy rich compounds such as ATP and NADPH.
It is also called as light dependent reaction of photosynthesis. It includes four major protein complexes: photosystem II, photosystem I, cytochrome b6f complex, and ATP synthase.
The electron first gets excited from chlorophyll a present in the reaction center (P₆₈₀ and P₇₀₀) of two photosystems (PS II and PS I) . The electron in PS II is replenished by photolysis of water.
Different electron carriers (such as plastoquinone, plastocyanin, pheophytin, chlorophyll A₀ etc) are present which help in transferring this high energy electron from one complex to another. NADP⁺ is the final acceptor of the electron and gets reduced to NADPH.
NADPH and ATP are then used in dark reaction in order to fix carbon into sugars.
Answer:
d is the answer
Explanation:
In cell biology, mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. The different stages of Mitosis all together define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two daughter cells genetically identical to each other.
