Answer: Animals use only respiration, while plants use both photosynthesis and respiration.
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 correct answers are C. Amount of rainfall, and D. Wind speed.
Explanation
Radars are instruments that were created by humans to detect objects, people, places, among others, through signals. Radars are devices used in different fields such as war, aviation, climatology, geography, among others. One of the best known is the Doppler radar, which is a climatological tool that is used to detect the intensity, size, quantity, and direction of rainfall. Likewise, rainfall is influenced by the direction and speed of the wind, data that can also be obtained using this tool. One of the purposes for which this object was created was the early detection of natural phenomena related to rains, and winds such as hurricanes, electric storms, hail, among others. Therefore, the two objects that scientists can obtain with a radar are C. Amount of rainfall, and D. Wind speed.
