Chem + Bio for ACT Science Section

– Higher temperatures will (usually) increase reaction rate, colder temperatures will (usually) decrease reaction rate.

– Amoebas: unicellular, have a nucleus, lack cell wall

– Trophic level: the higher in a food chain an organism is, the higher its trophic level is. Producers have a lower trophic level than consumers.

– Accuracy vs. Precision in scientific measurement: Accuracy means measurements are close to a known value, precision means measurements are close to each other.

– Endothermic means warm-blooded (mammals, birds) while ectothermic means cold-blooded (reptiles, amphibians, fish)
