Meg researched the biodiversity in four water ecosystems. W - low niche diversity and warm water temperatures
X - low niche diversity and cold water temperatures
Y - high niche diversity and cold water temperatures
Z - high niche diversity and warm water temperatures

Which ecosystem likely has the highest biodiversity?

i don't know, but does anyone wanna be friends? i'm doing my homework at 1: 49 in the morning : /

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.

2%? i tried finding the exact sorry if it's not 100% correct ; -;

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
