Check all that apply.Carbon is the basis of all living things.Sulfur is found in bones, where it provides strength.Nitrogen is found in certain foods.Oxygen and hydrogen combine with each other to form water.Only carbon, hydrogen, and phosphorus are found in organic compounds.Carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulfur are found in organic compounds.
Answer
A
Carbon is the basis of all living things.
B
Sulfur is found in bones, where it provides strength.
C
Nitrogen is found in certain foods.
D
Oxygen and hydrogen combine with each other to form water.
E
Only carbon, hydrogen, and phosphorus are found in organic compounds.
F
Carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulfur are found in organic compounds.
Explanation
The six elements commonly found in living things are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur, often shortened to CHNOPS. Carbon is the basis of organic molecules, and all six elements occur in organic compounds, so A and F are correct. Nitrogen occurs in foods such as protein-rich foods, and hydrogen and oxygen combine to make water, so C and D are also correct. B is incorrect because calcium, not sulfur, is the main mineral that gives bones strength; E leaves out several elements found in organic compounds.
