What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is an enzyme-substrate complex?

Back

An enzyme-substrate complex is formed when an enzyme binds to its specific substrate, facilitating a chemical reaction.

Front

What conditions do enzymes require for optimum activity?

Back

Enzymes require specific temperature and pH conditions to function effectively.

Front

What is the minimum number of cells an organism must have to be considered living?

Back

An organism must have at least 1 cell to be considered living.

Front

What is an independent variable in an experiment?

Front

What does a population graph show?

Back

A population graph typically shows the growth or decline of a population over time.

Front

What is the role of pepsin in digestion?

Back

Pepsin is an enzyme that breaks down proteins into smaller peptides in the acidic environment of the stomach.

Front

What is the effect of light on plant growth?

Back

Light is an essential factor for photosynthesis, and its amount can significantly affect the growth rate of plants.

Front

What is the significance of genetic diversity in a population?

Back

Genetic diversity is important for the survival and adaptability of a population, allowing it to respond to environmental changes.
