Answer:
Inhibit control over ions.
Explanation:
The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.
The statement that describes the ability of the cell membrane to allow various substance to move through is that the cell membrane is preamble and allows only certain substances to pass through.
Explanation:
The plasma membrane is preamble, hydrophobic molecules and small polar molecules diffuse through lipid layer. The integral membrane proteins enable large polar molecules to pass through the membrane.
Some molecules can cross the membrane like hydrocarbons and oxygen. Whereas the large molecules like glucose and sugars cannot cross. The water pass through lipid.
1.Gravity caused the disk-shaped nebula to shrink.
<span> A cloud of gas and dust started to shrink or more corectly started condensate, due to the force of its own gravity. This process started slow, but increased in velocity as more material were moving toward the center.</span>
2.<span>Rotational motion caused the nebula to flatten out in its disk-like shape.</span> The nebula spined counterclockwise to conserve the angular momentum of the material of the material that were going to the center. This rotation, made the materials that were not in the center flatten out, that's why it looks like a disk.
Answer and explanation:
If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.
<u>The cell contains a </u><u>more concentrated solution</u><u> than the solution in the container</u>. The difference in concentration would produce an <em>osmotic gradient</em> that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.
In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
I was able to check the image from other source. The answer should be "<span>Storage of needed components or cellular waste."</span>
