Answer:
1. George O’Malley (Season 5, Episode 24)
The world collectively gasped when George was revealed to be on the other side of the elevator doors, dressed in his Army uniform, ready to guide Izzie (Katherine Heigl) to the afterlife. This intense Season 5 ending was the audience’s first time witnessing the death of a main circle doctor, forever raising the stakes to come. From Callie recognizing the freckle, to John Doe tracing “007” into Meredith’s palm, each moment created goosebumps. The underdog of the interns didn’t deserve to go out being dragged under a bus, but it’s only fitting that he did it to save someone else’s life.
2. Denny Duquette (Season 2, Episode 27)
Love makes people do crazy things; but, unfortunately cutting L-Vad wires, breaking the law, and Izzie almost losing her job couldn’t save Denny Duquette from death. Isabel and Denny’s love story was the first flame that could’ve shone brighter than Meredith and Derek’s. It’s largely why the death of Denny was so heartbreakingly tragic. Although Izzie seemed to move on, Denny’s ghostly cameo in Season 5 made it clear the love story was always doomed.

Answer:
The answer is letter c, The structure of individual neurons.
Explanation:
Brain-imaging technique- <u><em>this comprises of different techniques for analyzing the brain's activities as well as structure, function and other problems.</em></u>
There are many brain-imaging techniques such as <u>Positron Emission Tomography or PET,</u> which traces the part of the brain that is activated during specific tasks as well as the localization of brain activity in response to a specific stimulus. These areas are seen with high radioactivity.
Patterns of blood flow in the brain can be detected by using <u>MRI (Magnetic Resonance Imaging) test.</u> There is an increase in blood flow to areas in the brain with high activity level.
With the explanation given, it shows that letter c is the only choice that the brain-imaging techniques cannot determine.
Answer:
The answer to the question: Where does the stimulus occur in order to initiate an AP, would be, B: Dendrites.
Explanation:
When an impulse is to be generated and passed on as an action potential towards a corresponding neuronal cell, and a final affected organ, the neurons need first to be stimulated so that an action potential begins. This stimulus comes as a neurotransmitter released by other neurons near the one that will be stimulated. This neurotransmitter will bind to the receptors on the dendrites of the neuron to be stimulated and immediately this will cause the ion channels, gated and non-gated, to open and close so that an action potential can be initiated. The cell body then initiates the first action potential, and will in turn stimulate the axon to also start their own action potential, which will, like a domino effect, move down to the axon terminals. This process will be followed all along a neuronal circuit.
Answer:
Diffusion is the net movement of any substance from a higher concentration region to the lower concentration region. It is conducting by a concentration gradient.
Osmosis is a process in which solvent (molecules) pass through a semipermeable membrane (SPM) from a lower concentration solution region to a higher concentration region so it equalizes the concentrations on each side of the SPM.
A <u>hypotonic solution</u> is a solution that has a higher concentration of solutes inside the cell than outside of the cell. Thus the movement of water is from outside to the inside of the cell.
A <u>hypertonic solution</u> is a solution in which solutes concentration is greater outside the cell and low concentration inside. The movement of water is from inside the cell to outside the cell.
An <u>isotonic solution</u> where two solutions having the same concentration inside and outside of the cell so there is free movement of molecules across a semipermeable membrane.
