What do mudstone and sedimentary rocks formed from the remains of once-living plants and animals have in common?

They are made up of the same kinds of minerals.

                     Hope this helps, Have a great day :)

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.

explanation:

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
