1. In the passage, the scientist, Yoshinori Ohsumi, found evidence of cellular autophagy? What is autophagy?

See explanation

Explanation:

Autophagy is simply a way by which ones body cleans out the cells that are damaged so that newer and healthier cells can be regenerated.

Autophagy is a natural process for cell rejuvenation. Autophagy helps to remove toxic proteins and also provide energy for the cells that can benefit from repair.

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.
