Answer 1

Statement 3 is false

Answer 2

Answer:

This is false: 3.Cells are composed primarily of inorganic molecules

Explanation:

Water, inorganic compounds and organic molecules form approximately 75-85% of the weight of living matter. Of all, water is the most abundant, about 70%, while inorganic compounds only represent approximately 1% of the cell composition. The rest is composed of macromolecules such as proteins, polysaccharides, lipids and nucleic acids. Cells have four types of organic molecules: sugars, fatty acids, nucleotides and amino acids.
