answer: 
When you increase the temperature of a substance its volume increases.(This is also known as Charles law~> T and V are directly correlated)
When the substances volume increases its density decreases.
Density:Mass/Volume

Answer:
The suitable option will be - B
Citric acid cycle
Explanation:
The results were -
Glucose: None
CO2: Increase
O2: None
ATP: Increase
NADH: Increase
- We know that the Citric acid cycle is also known as the TCA cycle (tricarboxylic acid cycle) or the Krebs cycle. This cycle occurs in Mitochondria in case of eukaryotes. In this cycle acetyl-CoA is oxidized which comes from carbohydrates, proteins and fats and energy is released in the form of ATP.  
- water is also used in this process. NAD+ gets reduced to NADPH. In this system carbon dioxide is produced as a waste byproduct. ATP is produced as the main product. ATP is also used as a source of energy.
