Front

What happens to a population when the number of births equals the number of deaths?

Back

The growth of the population will stay the same.

Front

What is cohesion in terms of water molecules?

Back

Cohesion is the property of water molecules sticking to each other due to hydrogen bonding.

Front

What macromolecule is primarily responsible for storing energy?

Back

Lipids are the macromolecules that primarily store energy.

Front

What defines a polar molecule?

Back

A polar molecule has an opposite electrical charge on each end.

Front

What is the role of primary consumers in an ecosystem?

Front

What is the difference between adhesion and cohesion?

Back

Adhesion is the attraction between different substances, while cohesion is the attraction between similar substances.

Front

What is the significance of water's high specific heat?

Back

Water's high specific heat allows it to absorb and release heat without significant temperature changes, stabilizing climates.

Front

What is the function of carbohydrates in living organisms?

Back

Carbohydrates provide energy and serve as structural components in cells.
