What happens during respiration?

• Oxygen is released into the air.

• Glucose is broken down, releasing energy.

• Carbohydrates are released in the bloodstream.

• Water and carbon dioxide are converted into energy.

What forms around the chromatids during mitosis?

• two new chromosomes

• two new nuclei

• two new cells

What are the products of photosynthesis??

• carbon dioxide and water

• oxygen and water

• carbon dioxide and sugars
