Answer:
B. axon hillock
Explanation:
The axon hillock is the junction where the cyton connects with the axon. There is only one axon hillock in the neuron and it is a triangular depression of cell boy to the axon. The axons receives impulse from cyton carry to the different parts of the body. The axon hillock is also called initial segment. Because action potential starts here.
Myelin sheath is the cover or layer around the axon and helps in saltatory movement of impulse. The propagation of impulse is fast in myelinated neurons than the non-myelinated neurons.
The neurolemma is the neural membrane of the neurons. It is like the plasma membrane of the cell. The outer covering of neurons is called neurilemma.
Axon collateral is the end of the axon where axon terminals arise. They carry impulse and transmit to the synapse.
Answer: Microtubules function mainly in cellular movement.
- Microtubules are responsible for a variety of cell movements, including the intracellular transport and positioning of membrane vesicles and organelles, the separation of chromosomes at mitosis, and the beating of cilia and flagella.
- Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.
Answer:
2
Explanation:
Because if you add 1 to 8 you get 9 then subtract 9 by 7 then and your answer is 2
Both the sodium and the chlorine atoms need to obtain a stable electron configuration, thus, a complete outer shell of eight electrons.
Sodiums electron design is 2,8,1 and chlorines electron setup is 2,8,7. So all together for the two molecules of the two components to get a total external shell of eight electrons, sodium will give one electron to chlorine, and the chlorine particle will acknowledge the gave electron when responded with each other.
This outcomes in the sodium particle having an electron arrangement of 2,8 so is currently total. The chloride particle currently has an electron configuration of 2,8,8.
Since the molecules have moved toward becoming particles to end up stable, the Na+ and the Cl-particles draw in one another because of their contrary charges, which results in an ionic bond.
This is the reason sodium and chlorine cling to each other when responded.
