Answer
read the scientific question below.
"does sunlight make plants live? "
what is a likely hypothesis for the question?

a. yes, sunlight makes plants live.
b. no, sunlight does not make plants grow.
c. if we place a plant in the shade, then it will die.
d. if we place two plants in sunlight, then they will grow differently.

All living things need water and food. Light is nourishment for plants. They use it in a vital process known as photosynthesis, where chloroplasts capture the energy of light, sparking multiple metabolic reactions — one of which creates plant sugars (food).

So your answer would be A. Yes, sunlight helps plants to live

thinking it would be physical characteristics

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.
