Homeostasis 3.4 Review

Homeostasis

• allows for a wildly fluctuating internal environment
• is impossible in vertebrates
• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation
• is the maintenance of a relatively stable external environment and often incorporates a form of feedback regulation

Diffusion is when molecules...

• are water molecules and move across the cell membrane

• move from a gradient of low to high concentration

• are pumped across the cell membrane

• move from a gradient of high to low concentration

What process is represented by the equation?

• Cellular respiration
• Photosynthesis
• Osmosis
• Homeostatic equilibration

Which is not a product of cellular respiration?

• Carbon dioxide
• Oxygen
• Water
• ATP

Which describes the relationship between cellular respiration and photosynthesis?

• The products of one are the reactants of the other.
• The products are the same for both.
• The reactants are the same for both.
• They are reverse processes of each other.
