1. When deciding which side of a biomolecule would orient itself toward the water in cytoplasm, the groups would be directed toward the water molecules. 2. When deciding which biomolecules would interact with a hydrocarbon chain, the portions of a biomolecule would orient themselves toward the chain.

4. Nonpolar groups in biomolecules are often characterized by functional groups containing the element .
5. When looking at ionizable groups, two ions of the same charge, such as two cations, are each other while two ions of the opposite charge, such as one cation and one anion, are each other.

1. Polar

2. Non-polar

3. Nitrogen or oxygen

4. Carbon

5. Repelled by; attracted to

Explanation:

1. When deciding which side of a biomolecule would orient itself toward the water in cytoplasm, the polar groups would be directed toward the water molecules. This is because like dissolves like, thus, polar groups dissolve in water which is polar.

2. When deciding which biomolecules would interact with a hydrocarbon chain, the non-polar portions of a biomolecule would orient themselves toward the chain. This is because like dissolves like as in the non-polar groups being attracted to the non-polar chain.

3. Polar groups in biomolecules are often characterized by functional groups containing elements such as nitrogen or, oxygen. This is because both elements are strongly electronegative, thereby forming charged particles, ions.

4. Nonpolar groups in biomolecules are often characterized by functional groups containing the element carbon. This is because carbon is neither strongly electropositive or electronegative.

5. When looking at ionizable groups, two ions of the same charge, such as two cations, are repelled by each other while two ions of the opposite charge, such as one cation and one anion, are attracted to each other. This is because like charges repel while unlike charges attract.

it means there are 3 atoms of oxygen

the answer would be a
