Answer:
True.
Explanation:
The unequal distribution of ions inside and outside of the cell makes the membrane potential of the cell. The potential is important for the conduction of the impulse and generation of the action potential.
The resting membrane potential of the nerve impulse is maintained by the presence of large potassium ions inside the cell. The resting membrane potential is -70mV. The depolarization of the membrane occurs due to influx of the sodium ions.
Thus, the answer is true.
Animals that use echolocation. Bats, whales, dolphins, a few birds like the nocturnal oilbird and some swiftlets, some shrews and the similar tenrec from Madagascar are all known to echolocate.
A. Organisms with less desirable traits do not reproduce
is the answer
Answer: During mitosis a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells.
Explanation:
Answer:
from the axon hillock toward the axon terminals.
Explanation:
Axon hillock is a cone-shaped elevation of an axon. It is the region where axons join the cell body. In most neurons, nerve impulses arise at the junction of the axon hillock and the initial segment of axons. This region is called the trigger zone. From this region, a nerve impulse travels towards axon terminals. Axon terminals may have synaptic end bulbs at their tips. As nerve impulse travel from axon hillock to the axon terminal, synaptic vesicles having neurotransmitters are released into the synaptic cleft.
