1. A scientist tests a small section of a carrot root to determine which molecules were present. The basic results showed that the molecules contained carbon, hydrogen, and oxygen, with some arranged in a ringed pattern, providing structure and energy to the root. What inference can be made from this data? A) The molecules are a type of carbohydrate
B) The carrot root is mainly composed of proteins
C) The carrot contains some type of sugar
D) Both A and C are correct
2. Which of the following is an element found in all organic compounds?
A) Protein
B) Zinc
C) Iron
D) Carbon

they are c. hope this !

answer: c.

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
