Question

what process do cells rely on when oxygen is unavailable? neutral respiration anaerobic respiration chemosynthesis

Explanation:

To determine the process cells use without oxygen, we analyze the options:

• "Neutral respiration" is not a recognized cellular respiration term.
• "Anaerobic respiration" is the process cells (like muscle cells or yeast) use to produce ATP when oxygen is absent, involving glycolysis and fermentation.
• "Chemosynthesis" is used by some bacteria to make food using chemical energy, not a cell's energy - production process without oxygen.

So, the correct process is anaerobic respiration.

Answer:

B. anaerobic respiration (assuming the middle option is labeled as B; if the options are ordered as: 1. neutral respiration, 2. anaerobic respiration, 3. chemosynthesis, then the answer is the second option, "anaerobic respiration")
