35. All organisms must be able to exchange chemical substances between their cells and
their environment. Some organisms are unicellular and others are multicellular. These
organisms have different strategies to obtain and use these chemical substances.
• What chemical substances must be exchanged between each organism and its environment?
• Describe the processes that cause these chemical substances to move into and out of cells.
• Describe the role of the cell membrane in the exchange of materials in both types of organisms.
- Describe the role of body systems in the exchange of materials in a multicellular organism.

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i.e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.

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?
