Answer:
it causes the depolarization of the target cell
Explanation:
Glutamate is an excitatory amino acid neurotransmitter that binds to specific receptors on the surface of target cells and thus causes its depolarization. During glutamate-mediated depolarization, the difference in charge inside and outside the cell is lost due to the entry of sodium and calcium positive ions into the postsynaptic cell (neuron) through specific ion channels. Moreover, glutamate binding also leads to the exit of potassium ions from the cell, thereby resulting in excitation. Through this mechanism, glutamate regulates many signaling pathways, such as those involved in memory, learning, emotions, cognition, motor control, etc.
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat.
Explanation:
When the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.
Answer:
The correct answer is lateral rectus muscles.
Explanation:
To see what is happening in his side, or what originated the loud noise, Ryan has to use his lateral rectus muscle. Lateral rectus is one of the five extra ocular muscles that help in movement of the eye balls and help to see what is happening in and around us. It is mostly responsible for abduction, i.e. the movement of the eye balls away from the center line of the body. Defect in this muscle can result in sixth nerve palsy.
