Acid rain throughout the northeast united states has lowered the ph of many ponds and lakes. the lowered ph will eventually result in the death of many aquatic animals. compare the map of the u. s. with the ph tolerance range for the organisms listed. based on the tolerances seen here, which aquatic organisms are least likely to survive in the northeastern states?
a) only the clam will survive.
b) all of the aquatic organisms will die.
c) all the organisms with a lower limit of 5.0 will survive.
d) all of the fish species will die; the others will survive.

examples of nucleic acids are deoxyribonucleic acid (dna) and ribonucleic acid (rna).

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
