When the Universe was very young, it was likely infused with dark energy, but with less space and everything closer together, gravity had the upper hand, and it was slowly braking the expansion.

When applied to the simplest two-electron molecule, H < sub > 2 </ sub >, valence bond theory, even at the simplest Heitler-London approach, gives a much closer approximation to the bond energy, and it provides a much more accurate representation of the behavior of the electrons as chemical bonds are formed and broken.

When awareness is focused on memories of past experiences and mental verbalisations, the energy flow to the head chakra increases and the energy flow to the heart chakra lessens.

When the body is expending more energy than it is consuming ( e. g. when exercising ), the body's cells rely on internally stored energy sources, such as complex carbohydrates and fats, for energy.

When glycogen is nearly depleted, the body begins lipolysis, the mobilization and catabolism of fat stores for energy.

) When a nucleotide is being added to a growing DNA strand, two of the phosphates are removed and the energy produced creates a phosphodiester bond that attaches the remaining phosphate to the growing chain.

When an electron in an excited molecule or atom descends to a lower energy level, it emits a photon of light equal to the energy difference.

When combined with setting transparency, this allows an Amiga to overlay an external video source with graphics.

When a continuum radiation source is used for AAS, it is necessary to use a high-resolution monochromator, as will be discussed later.

When a continuum radiation source is used for AAS measurement it is indispensable to work with a high-resolution monochromator.

When a metal wire is connected across the two terminals of a DC voltage source such as a battery, the source places an electric field across the conductor.

When exposed to sunlight, artificial light, or infrared radiation ( even the heat of a hand nearby can be enough ), the vanes turn with no apparent motive power, the dark sides retreating from the radiation source and the light sides advancing.

When blood glucose levels fall below a certain level, the body begins to use stored sugar as an energy source through glycogenolysis, which breaks down the glycogen stored in the liver and muscles into glucose, which can then be utilized as an energy source.
