Why do scientists believe that the earliest life forms most likely lived in the oceans? chemicals could not react to form complex molecules without water. early earth did not have an ozone layer. the land would have been too cold for life to form there first. all life relies on water.

The dissociation energy of a molecule is the energy required tobreak apart the molecule into its separate atoms. the dissociationenergy for a particular molecule is 5.48 x 10-18 j. suppose that this energy is provided by a single photon. determinethe (a) wavelength and (b) frequency of the photon

The metric unit of electrical power is the watt volt ampere ohm
