Answer:
The correct answer is option C (voltage gated Na+ channels).
Explanation:
Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.
The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.
At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.
Thus, option C (voltage-gated Na+ channels) is the correct answer.
Answer:
Choice B
Explanation:
"Permeable" means "Letting solids or liquids through (a material.)" "Semi" means "half or partly." So "semipermeable" means allowing some objects through, but not all.
Answer:The Null hypothesis state that the mean hemoglobin level for all the children in Jordan is 12g/dl.
While the Alternative Hypothesis state that the mean hemoglobin level for all the children in Jordan is less than 12g/dl
Explanation:
The Null hypothesis H0: This is the hypothesis that state that there is no statistical difference between the two variables in the hypothesis. It is the hypothesis that the researcher is work to nullify.
The Alternative hypothesis H1: This is the hypothesis that states there is a statistically difference between two variables.
It cannot survive because an earth worm will not become 2 new worm. The head of the worm may survive and regenerate a tail. But if original tail of the worm may not survive because it will not be able to grow a new head or the rest of its vital organs and it will die. I hope this helps. :)
