In darwin's theory of evolution, adaptation means that all organisms adapt to their environment.
true false

True

Explanation:

As per Darwin’s theory, all species adapt to the environment in which they live. All organism adapt their physical traits and habits under the influence of their surrounding environment. For example – in England during the industrial revolution, the environment got polluted due to which the insects with light colored wings adapted to reproduce dark color winged offspring so that they are not identified by its predators.

Hence, the given statement is true.

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.
