Answer:
the correct sequence of the events happened during nerve impulse is (d): 2,1,4,3
Explanation:
Originally K+ ions remains inward the membranes while Na+ ions remains outward to maintain a resting potential of membrane.
Upon stimuli Sodium channels open on membrane and Na+ diffuses inward leading to the depolarization of membrane that is it becoming more positive due to Na+ and K+ ions.
To regain it polarized state or in repolarization state Potassium channels open and K+ begun to diffuse outward while Sodium channels gets closed and Na+ ions remains inside the membrane.
Potassium channels are not efficient as compared to Sodium Channels, so an excess amount of K+ion move outward so Hyperpolarization state achieved.
As the both ions are on the wrong side and will not be available for the next nerve impulse. Hence in Refractory period by the help of Na+/K+ pum, both ions move back to their original place and membrane achieve its resting membrane potential state.
B) Landslides
Hope this helped, If it did mark me brainliest:)
The hippocampus is associated with memories for events and facts, known as Episodic memory whereas the cerebellum is associated with memories for skills and abilities, known as procedural memory.
Explanation:
Storage of memory is not the work of a particular part of brain but it is associated with several parts such as amygdala, hippocampus, cerebellum etc.
Hippocampus is the part of emotional brain and plays a great role in remembering events or episodes and recognition.
The cerebellum is the part of the brain that associates itself with learning and skill development.
