Osmosis

A passive movement of water molecules through a semi permeable membrane. Water moves from an area of low solute concentration to high solute concentration

Active Transport

An active movement where an input of energy is required. Particles move from low concentration to high concentration

What does Homozygous dominant mean?

It has two dominant

what does heterozygous mean?

It refers to a pair of genes where one is dominant and one is recessive.

Ribonucleic Acid

Diffusion

The passive movement of particles from an area of high concentration to low concentration. This happens along a concentration gradient
