Water is essential for life. its special properties make water the single most important molecule in plant life. which of the following properties of water enable it to move from the roots to the leaves of plants?
a: water exhibits cohesive behavior.

b: water expands as it freezes.

c: water is able to moderate temperature.

d: water is an excellent solvent.

A, Water exhibits cohesive behaviour

Explanation:

This is because they are polar molecules so they attract.

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.
