examples include palm oil.
they have fewer hydrogen atoms than saturated fatty acids.
question 2 (1 point)
what is a nucleotide made of?
an amino acid, a sugar, and a nitrogenous base
a phosphate group, a sugar, and a nitrogenous base
dna, rna and an amino acid
adenine, sugar, and a nitrogenous base

Explanation:

Question 1

• Unsaturated fatty acids have at least one carbon - carbon double bond. This double bond causes the molecules to be loosely packed. Also, because of the double bond, they have fewer hydrogen atoms compared to saturated fatty acids (which have only single bonds). Saturated fatty acids are solid at room temperature, and palm oil is a saturated fat.

A nucleotide is composed of a phosphate group, a sugar (either ribose in RNA or deoxyribose in DNA), and a nitrogenous base (such as adenine, thymine, cytosine, guanine in DNA or adenine, uracil, cytosine, guanine in RNA). An amino acid is a component of proteins, not nucleotides. DNA and RNA are made up of nucleotides, not the other way around. Adenine is just one of the nitrogenous bases.

Answer:

They are loosely packed molecules.
They have at least one carbon - carbon double bond.
They have fewer hydrogen atoms than saturated fatty acids.
