A student created the model of the ATP-ADP cycle shown below. How should the model be changed to accurately show the cycle. A. The arrows in the model should point in the opposite directions to show ADP releasing its energy to form ATP

B.“ATP” and “ADP” should switch positions because ATP is a high energy molecule and ADP is a low energy molecule.

C.“Energy from Food/Light/etc.” should be going out of the cycle rather than into the cycle. Energy from food breaks down ADP into ATP.

D.“Energy used for cellular work” should be going into the cycle rather than out of the cycle. Energy for cellular work breaks down ADP into ATP.

What percentage of light hits earth's surface directly?

What molecules does hemoglobin decay into over time

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
