Neuron has three main. The cell body directs all activities of the neuron. Dendrites extend out from the cell body and receive messages from other nerve cells.

How does facilitated transport (facilitated diffusion) help a cell maintain homeostasis?
7nadin3 [17]
Diffusion is when particles move from an area of high concentration to an area of low concentration. Think of it like a little kid party with two bouncy houses. Let's say that both bouncy houses have the same number of kids, but then half of the people in one bouncy house decide to go get lunch. Then one bouncy house is really full and the other almost empty! So you move to the empty bouncy house so you have more space to jump. This is diffusion. So it helps homeostasis because (back to the bouncy house example) you helped even out the two bouncy houses. Now let's say the kids come back from lunch. Now that bouncy house is too crowded so you move back to the now-emptier one. This is diffusion and you would be helping maintain homeostasis, or an equal level, in both bouncy houses.

Which of the following explains why nonrenewable energy resources are still so widely used. Select multiple
egoroff_w [7]
Non renewable resources can be very expensive, especially in capital outlay. For example, wind energy is very expensive to get started. The batteries alone are a headache. What do you do with those batteries whose life is over? How do you dispose of them? It isn't an easy problem to solve.

Then there's the labor part of wind energy. If they are manufactured in Denver Co and they receive an order from Maine, the blades require a wooden plywood box to be made. Plywood is roughly 20$ a 1/2 sheet (in Canada) to say nothing of the carpenter needed to make the box. I'm told that it takes a good day and one half just to make that box alone. That's for 1 blade. Then there's the shipping cost for 3 blades. Then there's the cost of making the blades which require highly skilled workers. 

Then there's the problem of wind, (or lack thereof). the problems just keep on going up and the expenses with them.
