Answer:

o multiply the mass of each isotope by the decimal fraction representing its abundance naturally, then add all these products  together.

Explanation:

To find the average atomic mass of an atom, take the weighted average of all naturally occurring isotopes of an element and sum them together.

  • The average atomic mass is determined from the geonormal abundances of the isotopes.

 Average mass of all isotopes  =  summation of all the  mass of isotopes of the element x abundance of the isotope.

 The abundance of the isotope is usually taken as a decimal fraction.

Answer:

Carbon dioxide is moving out of the living things.

Explanation:

The food materials eaten by living things contain carbon in the form of complex organic matter. When living things feed, they ingest this complex organic material into their bodies.

During the process of digestion, this complex organic material is broken down to give glucose. Glucose is the energy molecule in living things. Excess glucose in the body is stored as glycogen.

During cellular respiration, glucose is broken down to release carbon dioxide. Hence, at night when the giraffe has stopped eating, cellular respiration continues to occur and carbon dioxide is released, that is, carbon dioxide continues to move out of living things at night.
