The outer rim of a plastic disk is thick and heavy. Besides making it easier to catch, how does this affect the rotational properties of the plastic disk?

If you're passing light. So let's just say here is my light through to polarize er's. And I'm just gonna describe my polarizer here as a vertical slit. Here it's What happens here is the light that comes through. Must have this vertical orientation. And so if I had a second polarizer that was blocking this light, the type of polarizer that it would need to be is going to be one. That, for instance, in this case, is actually a horizontal. So the vertical stuff that passed to through that first lit When it hits this, you get nothing coming out, all right, And for this to be true, these to polarize er's must be 90 degrees off from each other, right? Or they must be perpendicular to each other, so of light passes through one polarizer. And then it's another polarizer that is perpendicular to the 1st 1 It will end up blocking all the light

These are the vertebrae. The inter vertical distance are in blue. The interviewer. Both disks help with cushioning, acting as a shock absorber between the actual vertebrates. That is the main function of those inter vertebral discs.

I heard one time is a subset of major neighboring s and he's your other teen. A polymorphisms seen on a single chromosome chromosome region usually inherited together. Set gets a linkage. Ironically, combination in the chromosome region can divine the have the type and create new reading Brian Tabb types.

So describe the structure and function of an inter vertebral disc. So, uh, right off the bat when we look at where an inter vertebral disc might be located, so it's gonna be between is it is just to vertebrate, so it's like a joint. So this here in green is the inter vertebral disc, and you can see it kind of looks like a cushion between two, and that's actually its main function. So instead of transferring stresses all up and down the bones of the spine, you have this cushion like softer joint between each vertebra, uh, so that you can absorb shock. So when we get into the structure here you have this outer portion called annual ist fibrosis, and it's ah more fibrous, sort of tougher part. And then on the inside it is nucleus pull posters, which is a gel like structure, sort of add to that cushioning effect
