Question

which statements describe the importance of the six elements found in all living things? check all that apply
□ carbon, oxygen, hydrogen, nitrogen, and phosphorus are all involved in creating genetic material.
□ most of the elements are seen and used to create important compounds in living organisms, but not all.
□ proteins are created by carbon, oxygen, hydrogen, nitrogen, and sulfur.
□ elements can combine to form all the substances found on earth.
done

Explanation:

1. For the first statement: Genetic material (DNA/RNA) contains carbon, oxygen, hydrogen, nitrogen, and phosphorus (in phosphate groups), so this is correct.
2. For the second statement: All six elements (carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur) in living things are used to create important compounds, so this is incorrect.
3. For the third statement: Proteins are made of amino acids which contain carbon, oxygen, hydrogen, nitrogen, and often sulfur, so this is correct.
4. For the fourth statement: The six elements in living things don't form all substances on Earth (e.g., metals like iron not part of these six in living things' context), so this is incorrect.

Answer:

• Carbon, oxygen, hydrogen, nitrogen, and phosphorus are all involved in creating genetic material.
• Proteins are created by carbon, oxygen, hydrogen, nitrogen, and sulfur.
