• Natural Selection

• Asexual Reproduction

The production of new living organisms by combining genetic information from two individuals of different types (sexes)

• Sexual Reproduction

• Natural Selection

• Adaptation

A circular area around the spot of the antibiotic in which the bacteria colonies do not grow, the size of which correlates to the sensitivity of the bacteria to the antibiotic
