I belive the answer is a sand bar!
Answer:
Acidophilic and acidotolerant eukaryotic microorganisms such as algae, amoebas, ciliates, heliozoan and rotifers, not to mention filamentous fungi and yeasts.
Explanation:
Acidophilic and acidotolerant eukaryotic microorganisms such as algae, amoebas, ciliates, heliozoan and rotifers are the organisms which can survive in highly acidic solution that have large amounts of iron, sulfur dioxide, carbondioxide, and oxygen molecule. In these organisms algae is autotrophic whereas archaea, bacteria, fungi, yeasts and protozoa are heterotrophic.
The correct answer is...Once the enzyme binds to the specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.
Hope this helps:)
chlorine because it has 7 electrons on the outer shell
