If a plant cell had a mutation such that the cyclic electron flow is observed at a much higher rate, which photosystem is most likely mutated such that energy is absorbed at a lower rate?
PSI
PSII
Answer:
PSII
Explanation:
Non-cyclic phosphorylation involves both PSI and PSII. The process starts with the splitting of water and excitation of electrons of the reaction center of PSII upon the absorption of solar energy at the wavelength of 680 nm. Any mutation in PSII would not allow the non-cyclic phosphorylation to occur when only cyclic phosphorylation would occur. The process of cyclic phosphorylation includes only PS I. Its reaction center absorbs maximum light at 700 nm and is cycled back while supporting ATP synthesis. Therefore, if a plant performs cyclic phosphorylation at a higher rate and absorbs less energy, this means that mutation was in PSII.
The nurse should explain that myelosuppression is a common side effect of cancer treatments. The healthcare provider should explain to the patient that it is better to reduce or stall the treatment for a while because it would be more harmful to them if they continued.
Given what we know about the correlation between the liver temperature of a corpse and the estimated TOD, we can conclude that the estimated time of death is approximately 10:30 pm of the night before.
<h3>How do we estimate the TOD?</h3>
- This can be achieved using a mathematical formula.
- The formula in question involves taking the normal body temperature of a living human and subtracting the liver temperature of the body.
- The remaining is the difference in temperature.
- Given that a body will lose roughly 1.5 degrees worth of heat per hour, we divide the remaining number by this to get the amount of hours since the death.
- This leads us to the conclusion that this individual perished roughly 15.5 hours earlier.
Therefore, given the way in which we use the correlation between liver temperature and time to analyze and approximate a time of death, we can confirm that this individual will have perished at roughly 10:30 pm of the night before.

Im going to go with C only because most dont make sense.
