Question

16 multiple choice 1 point which molecule is the energy carrier in the cell? lipids nucleic acid atp 17 multiple choice 1 point homeostasis is: the way a cell reproduces maintaining a stable environment stimuli such as light, sounds or temperature 18 multiple choice 1 point the chemical activities an organism performs is called: movement stimuli metabolism homeostasis

Explanation:

• For question 16: ATP (adenosine - triphosphate) is the main energy - carrying molecule in the cell. It stores and releases energy for cellular processes. Lipids are mainly for energy storage in the long - term and nucleic acids are for storing genetic information.
• For question 17: Homeostasis is the process by which organisms maintain a stable internal environment. Cell reproduction is a different biological process, and stimuli like light, sounds or temperature are factors that can affect an organism but are not homeostasis.
• For question 18: Metabolism refers to all the chemical activities that an organism performs. Movement is a physical action, stimuli are external factors that can trigger a response, and homeostasis is about maintaining stability, not the chemical activities themselves.

Answer:

1. C. ATP
2. B. maintaining a stable environment
3. C. metabolism
