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.
Given what we know, we can confirm that as scientists study fossil records, they can learn much about the species, such as the traits and activities of the organisms in question.
<h3>What does each fossil type teach us?</h3>
- Trace fossils such as footprints can teach us about the activities of the organisms.
- Meanwhile, scientists will use body fossils to learn about the specific traits of early organisms.
- Body fossils can at times also provide insight as to the diet of the species.
Therefore, we can confirm that scientists will use body fossils to learn more about the traits and diets of early organisms while using the uncovered trace fossils to track the activities of these organisms.

Answer:
B) Identifying the minerals within it
Explanation:
Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date the age of rock layers.
