They also need energy to move and to stay alive
The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.
Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.
The internal structure of prokaryotic flagella is the same as the internal structure of eukaryotic flagella. Prokaryotic cells do not contain endoplasmic reticulum, Gold bodies, mitochondria, plastids, or membrane-bound vesicles.
Answer:
C) Student 2 has an explanation that is supported because eukaryotic cells have a nucleus, which is lacking completely in cell III.
