Several bacterial colonies are placed on a petri dish that contains agar with antibiotics. after 24 hours, ninety percent of the original bacterial colonies die, but the remaining ten percent survive and later reproduce. which of the following theories is demonstrated by this experiment?

Drag each tile to the correct box. the body monitors the levels of oxygen in the blood to regulate breathing. isabel is running in a marathon and is near the finish line. she feels out of breath. how will her nervous system work to generate a reaction? arrange the tiles in chronological order. isabel's breathing rate increases. sensory receptors in the arteries detect low oxygen levels. the brain sends signals through motor neurons. sensory neurons generate an impulse. the central nervous system relays an impulse to certain brain regions.
