Answer:
W and Z
Explanation:
Atoms of the SAME element OR two atoms of DIFFERENT elements will form a MOLECULE.
E.g. 2 atoms of hydrogen + 1 atom of oxygen => 1 molecule of water. This 1 molecule of water can also be called a compound.
Also, 2 atoms of Oxygen can combine to form 1 molecule of Oxygen. This 1 molecule of Oxygen cannot be referred to as a compound.
Atoms of DIFFERENT elements form a COMPOUND.
Therefore, compounds are molecules, but molecules are not compounds.
Thus, the combination of atoms that will form a molecule, but not a compound is:
W(oxygen) + Z(oxygen) = molecule
Answer:
A reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. A reaction that occurs in two or more elementary steps is called a multistep or complex reaction. ... The slowest step in a reaction mechanism is known as the rate-determining step.
The community with high blood varsity is represented with species richness
<h3>What is a community with high biodiversity?</h3>
A community with high biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. The reasons for variances in biodiversity are complex, but they include both natural and man-made causes.
The number of species per unit area is called Species Richness. If you have more number of species , more will be species richness hence stable will be the ecosystem. More species richness will contribute to increase in biodiversity also which is an important aspect biodiversity conservation.
