MRI mean Magnetic Resonance Imaging.
This is a big machine that detects tumors, bleeding and abnormalities in the Brain. :)
I hope this has helped you haha :)
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:
ΔS will be positive.
Explanation:
Denaturation may be defined as the loss of the biological activity of protein by changing the physical conditions of protein. Protein can be denatured by increasing temperature, pH and salts.
Entropy may be defined as the randomness of molecule. The entropy increase with increase in the randomness of the substance. Since, protein has been denatured, the random coil confirmation increase. This means the randomness of protein has been increased, this increase the entropy and makes it more positive.
Thus, entropy becomes more positive.
Answer:
glucose
Explanation:
Small nonpolar molecules, such as O2 and CO2, are soluble in the lipid bilayer and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot.
