Which of the following is the correct sequence of events in cellular respiration?

glycolysis → Krebs cycle → electron transport

Which is one of the ways that cellular respiration and photosynthesis are opposite processes?

weather is day-to-day and climate is average

Which of the following happens when a cell divides?

Each daughter cell receives own copy of parent cell’s DNA.

Why are stem cells important?

They have the potential to develop into other cell types.

Which of the following is true about nonrenewable resources?
