Conduct an investigation to provide evidence that living things are made of cells, either one cell or many different numbers and types of cells.

Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function. 

Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells. 

Use argument based on empirical evidence and scientific reasoning to support an explanation for how characteristic animal behaviors (e.g., nest building, herding, vocalization, colorful plumage) and specialized plant structures (e.g., bright flowers, flower nectar, odors that attract insects that transfer pollen, hard shells on nuts that squirrels bury) affect the probability of successful reproduction of animals and plants respectively.
