A scientist injected some cells with a drug that blocked glycolysis after NADH was formed, but before ATP and pyruvate were formed. All the other enzymes used in cellular metabolism were unaffected. How would the production of ATP in the cell be affected? The cell could not make ATP.
The cell could make ATP using fermentation.
The cell could make ATP using cellular respiration.
The cell could make ATP using the citric acid cycle.

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?

In 2001, records showed that local stocks of fish were down worldwide. yet, records of harvests indicated that fish were being taken at records rates. what was actually happening?
