Hope this helps you: Ecology is the study of how organisms interact with their environment<span>, including both abiotic (non-living) and biotic (living) aspects of the </span>environment<span>. It is a very broad definition and the science of ecology tends to overlap other biological sciences.</span>
Im pretty sure it would be kinetic <span />

Answer:
Masses of bromobenzene molecular ions will occur at 156 and 158 m/z.
Explanation:
The molecular ion peak is the signal in the mass spectrum of a compound that represents the molecular ion (denoted as M). Compounds that are composed of atoms having abundant isotope also shows M +1 and M+2 peaks (depending on the isotope).
In the given bromobenzene compound, an atom of bromine is present. The two isotopes with considerable relative abundance of Br are 79Br and 81Br with a difference of two units in their mass. This means that two molecular ion peaks with a difference of two units will appear in the mass spectrum. The mass of the whole compound is 156 amu. Hence, the molecular ion peaks will appear at 156 m/z and 158 m/z due to the two isotopes of bromine.
5 ml=5 cm³ , density=mass/volume=45/5= 9 g/cm³ therefore answer B
