Answer:

The ability to bring water into the gills when the mouth is closed would benefit a bottom dwelling shark or ray, because it would allow them to be more discreet when in the process of catching prey and they would be able to stop swimming. Most sharks have to continuously swim or else they would sink, while being able to bring water into the gills when the mouth is closed would highly benefit them and allow them to stop swimming for a moment.

Explanation:

I am not 100% sure this is the correct answer, but I am currently doing a lab on this, so I am using the knowledge I previously had and online resources. I am pretty confident though.

5. Nucleic Acids

6. Lipids

7. Proteins

8. Nucleic Acids

Explanation:

2. Carbohydrates  have the basic formula CH2O as carbohydrate is composed of of carbon and a 2:1 ratio of hydrogen to oxygen.

3. Lipids or fatty acid can be saturated or unsaturated, it depends on the number of hydrogen in the tail. Saturated fatty acids have single bonds while unsaturated fatty acid have some missing hydrogen in tail and form double bond.

4. Enzymes are example of proteins because enzymes are made up of many amino acids binded in a very specific and unique order and amino acid are building blocks of proteins.

5. Nucleic acid is the monomer consist of nucleotide as all nucleic acids are made up of same five pieces are uracil, guanine, thymine, cytosine, and adenine.

6. Lipids are considered as hydrophobic as it is composed of carbon and hydrogen and have mostly nonpolar carbon–hydrogen or carbon–carbon bonds.

7. Proteins are most complex macromolecules as they made up of  hundreds of amino acids and each amino acid has its own specific shape. All the properties of proteins depends on these specific amino acids

8. when some one look into mirror, they see their own image or phenotype characters which are due to the genetic makeup in the body. DNA is responsible for the phenotype and genotype where DNA is a nucleic acid. Hence, the , one will see while looking in the mirror is nucleic acid.
