Science Biology SOL Review

Front

Where does a cell spend most of its time?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, preparing for division.

Front

What is the probability of two heterozygous organisms having heterozygous offspring?

Back

The probability is 50%. This is determined using a Punnett square for a monohybrid cross.

Front

Define osmosis.

Back

Osmosis is the movement of water through a semi-permeable membrane from an area of higher water concentration to an area of lower water concentration.

Front

List the phases of meiosis.

Back

The phases of meiosis are Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.

Front

What is the function of enzymes?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.

Front

What is a heterozygous organism?

Back

A heterozygous organism has two different alleles for a specific gene, one inherited from each parent.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is a Punnett square?

Back

A Punnett square is a diagram used to predict the genetic outcomes of a cross between two organisms.

Front

Define semi-permeable membrane.

Back

A semi-permeable membrane allows certain molecules or ions to pass through it while blocking others.

Front

What is the role of water in osmosis?

Back

Water moves through a semi-permeable membrane to balance solute concentrations on both sides.
