Which of the following best describes what biomedical scientists study? how diseases spread within the body how life interacts with the environment how to maintain health through the study of nutrition and disease prevention how different systems within an organism are structured and how they function

The right option is; how different systems within an organism are structured and how they function

Biomedical scientists are scientists that studies how the human body works by observing the structure and the functions of different cells, organs and systems in the body. They also work by discovering new methods for treating diseases and creating improved diagnostic tools or techniques.

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.
