Neuron A and neuron B interact with neuron C. Neuron A will produce an EPSP of 2mV in neuron C; neuron B will produce an IPSP of 3mV in neuron C. The resting membrane potential in neuron C is -70mV and the threshold potential is -50mV. How many times does neuron A need to stimulate neuron C in order to produce an action potential in neuron C?

1) strawberry plants typically reproduce by making runners, which are miniature versions of themselves, that grow off of the roots and stems of the parent. this type of vegetative reproduction is known as a) pollination. b) fragmentation. c) binary fission. d) vegetative propogation.

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.

What type of reaction is photosynthesis
