Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of high water concentration to an area of low water concentration.

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is the same inside and outside the cell, resulting in no net movement of water.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is a tissue?

Back

A tissue is a group of related cells that work together to perform a specific function in a multicellular organism.

Front

What is the advantage of sexual reproduction?

Back

The advantage of sexual reproduction is that it increases genetic diversity, which can enhance the ability of a population to adapt to changing environments.

Front

What are the results of a genetic cross between TT and Tt?

Back

The results are TT, TT, Tt, Tt.

Front

What is the role of proteins in cells?

Back

Proteins perform a variety of functions including acting as enzymes, providing structure, and facilitating communication between cells.

Front

What is the difference between asexual and sexual reproduction?

Back

Asexual reproduction involves one parent and produces genetically identical offspring, while sexual reproduction involves two parents and produces genetically diverse offspring.

Front

What is a cell membrane?

Back

A cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.
