Carbon dioxide is released during the **Krebs cycle**.

In cellular respiration, one glucose molecule (C6H12O6) requires 6 oxygen molecules (O2) to fully oxidize into carbon dioxide and water. Therefore, with 13 O2 molecules available, you can calculate how many glucose molecules can react as follows:
- Each glucose requires 6 O2, so you can calculate how many full sets of 6 fit into 13:
\[ 13 \text{ O2} \div 6 \text{ O2/glucose} = 2.1667 \]
This means that you can fully oxidize **2 glucose molecules** with 12 O2 molecules, and you will have 1 O2 molecule left over.
So, the answer is **2**.
- Each glucose requires 6 O2, so you can calculate how many full sets of 6 fit into 13:

So, the answer is **2**.

For one glucose molecule, 6 oxygen (O2) molecules are required for cellular respiration. Therefore, for two glucose molecules, the calculation would be:
\[ 2 \text{ glucose} \times 6 \text{ O2/glucose} = 12 \text{ O2} \]
So, the answer is **12**.
\[ 2 \text{ glucose} \times 6 \text{ O2/glucose} = 12 \text{ O2} \]
So, the answer is **12**.

The activity that uses ATP to lower body temperature is **panting**. Panting helps increase evaporative cooling, which can reduce body temperature.

The correct response is: **Gram staining helps scientists visualize the composition of bacterial cells.**
Gram staining differentiates bacteria based on the composition of their cell walls, which indicates how they may respond to environmental conditions, such as the presence of antibiotics or their ability to react to other chemical agents.

The true statement about protists is: **Protists can be plant-like, animal-like, or fungus-like, based on their morphology.**
This captures the diversity of protists and their classification based on characteristics and functions, rather than rigid cellular structures like those found in plants.
