Once it is produced, where does it go? - ✅To another part of the same cell After food has been masticated in the oral cavity, where does it go next? - ✅pharynx The diffusion of nutrients through the walls of the digestive system is critical to homeostasis in the body. Where does the majority of this diffusion take place in the digestive system? - ✅small intestine As soon as an invader, known as a(n) _____, enters the body, the body begins to fight. - ✅pathogen Where is skeletal muscle found? - ✅attached to bones If a person smells something sweet, what form of information is this initially perceived as in the nervous system? - ✅sensory While hiking, a person is startled after encountering a bear. Her palms get sweaty and her heart starts racing. Which part of her nervous system was directly stimulated? - ✅sympathetic Which of the following types of tissues include cells of the immune system and of the blood? - ✅connective tissue Which best describes homeostasis? - ✅A relatively constant environment within the body Fertilization (the fusing of one sperm and an ovum) results in a(n) _________. -

Each of the five tigers has the same stripe pattern. Using his inductive reasoning, what does he logically assume based on this information? - ✅Each offspring will have the same stripe pattern

A researcher notices a positive correlation between the height of a plant and nutrient concentration over time. Based on this observation, what conclusion does he reach?

• ✅When the amount of nutrients available to the plant increases, its height also increases. Which statement best represents Mendel's experiments with garden peas? - ✅Mendel collaborated with others interested in genetics to develop heredity guidelines we still use today.
