Question

what facts would you select to show the major significance of the element carbon in the human body? check all that apply carbon has four valance electrons. carbons ionized form makes body fluids acidic. carbon forms the backbone of all organic molecules. carbon is the main constituent of water. carbon can form bonds with four different atoms.

Explanation:

• Carbon has 4 valence electrons, which allows it to form stable bonds, a key trait for its biological role.
• Carbon forms the backbone of all organic molecules, which are the basis of all biological structures in the human body.
• Carbon can form bonds with four different atoms, enabling the vast diversity of organic molecules needed for life.
• Water's main constituent is hydrogen and oxygen, not carbon.
• Carbon's ionized form does not make body fluids acidic; this is primarily related to hydrogen ions/bicarbonate buffering.

Answer:

☑ Carbon has four valence electrons.
☑ Carbon forms the backbone of all organic molecules.
☑ Carbon can form bonds with four different atoms.
