QUESTION 6 Assume that for a certain biploar cell in the retina, glutamate opens potassium ion channels. In the light, this bipolar cell will: O hyperpolarize O not hyperpolarize QUESTION 7 In chemoreceptors, ligand-gated ion channels that detect the chemical stimuli are also: O ionotropic receptors O metabotropic receptors QUESTION 8 Using the root "sarco", type in the specialized term for the muscle cell cytoplasm. QUESTION 9 Compared to weak sensory stimuli, strong sensory stimuli produce action potentials that are: O stronger, but nore more frequent O more frequent, but not stronger more frequent and stronger O neither stronger nor more frequent

Step 1: Introduction
A neuron is a specialized cell in the nervous system that transmits information through electrical and chemical signals. It consists of a cell body, dendrites (receivers of signals), and an axon (transmitter of signals). Neurons communicate with each other by sending electrical impulses called action potentials across synapses, which are tiny gaps between neurons, using neurotransmitters. They play a crucial role in processing and transmitting information in the nervous system, enabling functions like thinking, sensing, and controlling bodily movements.
