A heterodimer represents what level of protein structure? correct answers Quaternary Dopamine is most likely to induce signal transmission by action on which portion of a neuron? correct answers Post synaptic membrane Where do neurotransmitters function to induce signal transmission? correct answers Post synaptic membrane What is the difference between passive and facilitated diffusion? correct answers In passive diffusion, particles diffuse across a membrane from high to low concentrat...

Homeostasis correct answersRegulation of the body's internal environment; must respond to environmental challenges. Law of Mass Balance correct answersLaw that states that the amount of substance in the body is to remain constant, any gain must be offset by an equal loss. Negative feedback loop correct answersSomething is wrong in a body system that is sensed and there is a response that is generated which returns the system to a homeostatic state (stabilizes variable). Positive feedba...
