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.

Answer:
Option B. Renewable have no environmental concerns associated with them; nonrenewable cause damage to the environment.
Explanation: Renewable resources are those substances which can be recycled or reused after using it. Examples of renewable resources are hydro energy, solar energy and tidal energy etc. Renewable resources are occurs naturally while nonrenewable resources are those substances which cannot be recycled. These substances causes pollution in the environment. It is also found naturally. Examples are petrol, diesel and wood etc.
Answer:
Tissues
Explanation:
Tissues are organized group of cells carrying out specific coordinated functions. They are organizational structures that lies between cells and organs. A group of cells binds together using specialized proteins forming a tissue, furthermore, a group of different tissues are the building blocks for organs and plant structures creating a complete system.
