Explicación
The question is asking to verify the statements about the composition of water and the relative masses of hydrogen and oxygen. 1. "A large portion of an organism's mass is in the form of water." This statement is true. Water is a major component of most organisms, making up a significant percentage of their total body mass. In humans, for example, water constitutes about 60% of the body weight.2. "Water contains two hydrogen atoms and one oxygen atom." This statement is also true. The chemical formula for water is H2O, which indicates that each molecule of water is composed of two hydrogen atoms bonded to one oxygen atom.3. "The mass of oxygen is sixteen times that of hydrogen." This statement is true as well. The atomic mass of oxygen is approximately 16 times that of hydrogen. In the context of water, this means that the mass of the oxygen atom in a water molecule is 16 times the combined mass of the two hydrogen atoms.Therefore, all the statements provided in the question are correct, and the answer is "All of the above."
