Carbon dioxide and oxygen are two molecules that undergo this simple diffusion through the membrane.
Answer:
Azurite and Magnesite react with hydrochloric acid.
Explanation:
These 2 rocks contain the carbonate mineral calcite dolomite. Carbonate minerals are unstable in contact with hydrochloric acid. When acid begins to effervesce (fizz) on a specimen, a reaction takes place and bubbles of carbon dioxide evolve, thus indicating the presence of minerals like calcite dolomite.
Hope my answer is correct and helpful :)
If a species wanted to remain small in order to camouflage better!
Diffusion is important to organisms because it is the process by which useful molecules enter the body cellsand waste products are removed. Digested food molecules (amino acids, glucose) move down a concentration gradient from the intestine to the blood.
You got all of them right if you need help with fourth one I can’t see it
