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 element needed for cellular respiration is oxygen. Oxygen is essential in the final stage of cellular respiration, the Electron Transport Chain, where it acts as the final electron acceptor. The absence of oxygen would lead cells to resort to anaerobic respiration that yields less energy.
The element needed for cellular respiration is oxygen. Cellular respiration is a process by which cells break down glucose and other molecules in the presence of oxygen to produce energy. The process can be broken down into three stages: Glycolysis, Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain. Oxygen plays a crucial role in the final stage, the Electron Transport Chain, where it acts as the final electron acceptor and combines with the hydrogen ions to form water.
Without oxygen, the Electron Transport Chain cannot occur. If oxygen is not available, cells may resort to an alternative method known as anaerobic respiration, or fermentation, but this produces significantly less energy. Hence, oxygen is a vital element required for efficient cellular respiration.
