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

False
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
