Biology Midterm Review

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher solute concentration outside the cell than inside, causing water to move out of the cell, leading to cell shrinkage.

Front

What is an example of a living organism?

Back

Bacteria is an example of a living organism.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or manipulated in an experiment to test its effects.

Front

What is the primary function of the nucleus in a eukaryotic cell?

Back

The primary function of the nucleus is to store genetic information.

Front

What is an isotonic solution?

Back

An isotonic solution has the same solute concentration inside and outside of the cell, resulting in no net movement of water.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower solute concentration outside the cell than inside, causing water to move into the cell, leading to cell swelling.

Front

What is the role of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the purpose of a control group in an experiment?

Back

The control group serves as a standard for comparison, allowing researchers to determine the effect of the independent variable.
