Q1. Examine how the pancreatic endocrine hormones glucagon and insulin work antagonistically to maintain homeostasis in the body, throughout times of feast and times of famine.
Q2. Select two nonhuman species that interact with each other, as in bees and flowers, or predator and prey species, or two species that compete. Or, you may consider the effect of an environmental factor on living nonhuman organisms, such as the effects of light or sound on plants or animals, or how food preference, or nutrient quantity/quality affect plants or animals. These are just a few examples. Your observations might lead you to many other types of questions about living organisms, their interactions, and requirements for life.
