*The key function of each of the two photosystems is to absorb light and convert the energy of the absorbed light into redox energy, which drives electron transport.
In PS II (the first photosystem in the sequence), P680 is oxidized (which in turn oxidizes water), and the PS II primary electron acceptor is reduced (which in turn reduces the electron transport chain between the photosystems).
In PS I, the PS I primary electron acceptor is reduced (which in turn reduces other compounds that ultimately reduce NADP+ to NADPH), and P700 is oxidized (which in turn oxidizes the electron transport chain between the photosystems).
Answer:
The energy that was not passed on the next tropic level is lost as heat
Explanation:
In an ecosystem flow of energy occur from one tropic level to the next one as the organism of one tropic level eats another organism belongs to the tropic level that is lower from that of previous one.
The 10% of total energy of one tropic level is passed to the next tropic level the rest of the energy is lost as heat in the environment.
The end result of cytokinesis indicates the two cells with identical copies of DNA arise from a single parental cell.
<h3>What is Cytokinesis?</h3>
Cytokinesis may be defined as the process of separation of the cytoplasm at the end of mitosis.
Cytokinesis is the phase of mitosis which involves the overall division of cytoplasm and the construction of two copies of cells with identical DNA content.
It occurs after the process of karyokinesis, which results in the formation of two daughter cells from a single parental cell.
Therefore, it is well described above.

Answer:
D. Risk
Explanation:
RISK can be seen as a tendency or likelihood that a person or an individual may encounter, faced or be exposed to something that may be harmful or have an adverse health effect on such person Example a house that has a foundation that is not strong is an hazard reason been that their is likelihood or tendency that a person or an individual might be harmed if the house collapsed because the foundation of the building is not strong for the building to stand long on it without collapsing.
