How has science positively and negatively impacted the environment in the last 100 years?

How science transformed the world in 100 years Just over a hundred years ago, people had no idea how we inherit and pass on traits or how our genes regulate the body and how they interact with our environment. The negative is inexorable rises of the curves in the two graphs below are at the heart of the global warming problem. As humans have piled more cars onto roads and burned more coal and natural gas for electricity.

Explanation:

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

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.
