In alzheimer's disease patients, amyloid plaques develop that contain misfolded beta-amyloid proteins. based on this observation
Anuta_ua [19.1K]
Based on this observation you would predict that the MISFOLDED BETA AMYLOID PROTEINS COULD NOT BE REFOLDED BY THE CHAPERONE PROTEINS.
Chaperon proteins are proteins which assist newly formed proteins to form correctly. A protein that is already mis-folded can not be refolded by the chaperone proteins.

Is Water Wet? If So, What makes it wet, if not what makes it dry?
Monica [59]

Answer:

Water is a liquid. Water is not wet BECAUSE something is only wet when water is on that object.

Explanation:

For example, there is water is a glass cup, and then the glass cup spills onto the table, causing the table to be wet, BUT you can remove that water from the table with some paper towels or a rag. Therefore, the table is no longer wet. Or when you're out in the rain and it gets on your clothes and/or hair, then your clothes and/or hair is WET.

When you put water onto water, it's an addition of water, you don't say it's wet or wetter.

Now, let me further prove my point with a different element: Fire. Fire burns things, right? So, when fire is on an object, then that object is burned. And when you add fire to fire, it causes more fire; fire does not burn itself.

Therefore, water is NOT wet. Wet is an adjective to describe an object that has been touched by a liquid, in this case, water.

So, yeah, enjoy the rest of your day. I'm sure some would like to argue my point. Go ahead.
