Question

nucleic acids are a type of biological macromolecule, or carbon-based
molecule, found in all living organisms. their job is to store and transmit
genetic information. nucleic acids are crucial for the inheritance of traits from
one generation to the next. though there are different types of nucleic acids,
they are all made of carbon, hydrogen, oxygen, nitrogen, and phosphorus.

select the true statements.

nucleic acids are key to the inheritance of genetic traits.

nucleic acids are found in all living organisms.

nucleic acids contain carbon, hydrogen, oxygen, nitrogen, and
sulfur.

there is just one type of nucleic acid.

Explanation:

• For "Nucleic acids are key to the inheritance of genetic traits": The text says "Nucleic acids are crucial for the inheritance of traits from one generation to the next", so this is true.
• For "Nucleic acids are found in all living organisms": The text states "found in all living organisms", so this is true.
• For "Nucleic acids contain carbon, hydrogen, oxygen, nitrogen, and sulfur": The text says they are made of "carbon, hydrogen, oxygen, nitrogen, and phosphorus", not sulfur, so this is false.
• For "There is just one type of nucleic acid": The text says "there are different types of nucleic acids", so this is false.

Answer:

A. Nucleic acids are key to the inheritance of genetic traits
B. Nucleic acids are found in all living organisms
