Mutations cause different phenotypes that can be passed from parents to offspring
The most fit individuals in a population - those with
adaptations - Survive to pass on their alleles to offspring
Environments have limited resources such as food, habitat,
mates
more offspring are bom than can survive
.: The potential for populations or a species to increase in number
:: Genetic variation of individuals within populations
:: Competition for limited resources within the environment that individuals need to survive and reproduce
The proliferation of organisms that are better able to survive and reproduce in that environment

This is the diveristy of ecosystems natural communites and habits it is the variety of ways that species interact with each other and their environment

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.
