Answer:
The correct statement would be - the bacterial cell due to the largest surface-to-volume ratio.
Explanation:
The surface area to volume ratio plays a very important role in determining the rate of the diffusion enter and exit from the cell body. If the surface-to-volume ratio is lower then the rate of diffusion would be lower to similarly with an increase in the ratio, the rate of diffusion also increases.
So, the bacteria like small organism have a cell which is exposed to a large surface area to the surrounding in comparison of the human egg cell.
Thus, the correct answer would be - the bacterial cell due to the largest surface-to-volume ratio.
A smaller spherical bacterial cell with a radius of 3μm can more efficiently exchange materials with the external environment compared to a larger human egg cell with a radius of 100μm, due to its higher surface area-to-volume ratio.
The statement that correctly indicates the cell that is able to more efficiently exchange materials with the external environment is that the spherical bacterial cell with a radius of 3μm can more efficiently exchange materials. This is because a smaller cell has a higher surface area-to-volume ratio, allowing for a faster exchange of materials through the cell membrane. On the other hand, the human egg cell with a radius of 100μm, being larger, has a lower surface area-to-volume ratio and is less efficient in exchanging materials with the external environment.

The microscopic organisms at the base of the marine food chain are known as plankton.
Plankton are mostly microscopic animals and plants found drifting or floating I he ocean or in large bodies of fresh water , consumed as food by almost all aquatic animals.
Plankton which are more plant-like are referred to as phytoplankton, while plankton which more animal - like are referred to as zooplankton. However many plankton species are neither animal nor plant, rather they are organisms belonging to the kingdom Protista.
Examples of phytoplankton include diatoms, coccolithophores and dinoflagellates. These are the most common phytoplankton.
Zooplanktons include jellyfish, Portuguese Man o' War, copepods and isopods.
(B) Sunlight excites electrons in Photosystem II.
(C) It produces ATP.
(D) It produces NADPH.
(E) It produces carbohydrates through carbon dioxide fixation.
Answer:
The correct answer will be option E.
Explanation:
The non-cyclic pathway or electron transport chain is the pathway which takes place in the light reaction.
The non-cyclic pathway starts from the PSII or P680 when the sunlight excites the electrons form the from the photosystem. This high energy electron is transferred to the higher energy level and loses its energy on the path.
The lost energy is used to form the ATP and NADPH which are used later in the formation of glucose during the dark reaction.
Thus, option E is the correct answer.
In the noncyclic electron pathway of photosynthesis, electrons are not boosted to a higher energy level in Photosystem I.
The statement that is NOT true about the noncyclic electron pathway is (A) Electrons are boosted to higher energy level in Photosystem I.
The noncyclic electron pathway is an important part of the light-dependent reactions of photosynthesis. In this pathway, electrons from photosystem II are excited by sunlight and transferred to photosystem I, where they are further excited to a higher energy level. This pathway ultimately produces ATP and NADPH, which are then used in the light-independent reactions to produce carbohydrates through carbon dioxide fixation.
