07 Biology IA Unit Two Review Flashcard - BIO IA HONORS

Front

What type of bond is formed when a pair of electrons is shared unequally between two atoms?

Back

Polar covalent bond: A type of covalent bond where electrons are shared unequally, resulting in a molecule with a slight charge difference.

Front

Where does water move in a hypertonic solution?

Back

Out of the cell: In a hypertonic solution, water moves out of the cell to balance solute concentrations.

Front

What are substances produced in a chemical reaction called?

Back

Products: The substances that result from the chemical reaction of reactants.

Front

Why does water move into a cell in a hypotonic solution?

Back

The concentration of solute (salt) is higher inside the cell than outside, causing water to flow in.

Front

Which type of cell contains a nucleus?

Back

Eukaryotic: Cells that have a nucleus and membrane-bound organelles.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is osmosis?

Back

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

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 organelles.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solute compared to another solution, causing cells to swell as water enters.
