a glacier made of ice can erode a landscape made of rock because there can be water held within the rock that gets frozen, and because water expands when it is frozen the rock breaks apart and the glacier grinds its' way 'downhill' (down a mountain range, a good example of this is the Appalachian mountain range) and carves out a significant amount of material that is below it, as well as the materials frozen inside of the glacier. so glaciers can freeze the rocks, and then scrape away any material that is softer than rock.
As viruses cannot reproduce by themselves, they depend on the host cells that they infect to reproduce
BLINK protein speeds up stomatal movements in response to light fluctuations resulting in improved plant growth and water use.
Plants can't move, so their “blinking” helps protect them from burning or bleaching when they are in bright sun.
I'm not sure if the first part is right, but I do know the second part is.
