REM sleep occur per night that happen between time intervals of one to two hours (Wolf-Meyer‚ 2012). REM sleep is important because of its restorative aspect in sleep cycles. A disturbance in this will put a person’s normal circadian sleep cycle or known as our “inner clock” out of place.

Nucleation As in solidification‚ nucleation occurs most easily on surfaces already present in the structure‚ thereby minimizing the surface energy term. Thus‚ the precipitates heterogeneously nucleate most easily at grain boundaries and other defects. Growth of the precipitates normally occurs by long-range diffusion and redistribution of atoms. Diffusing atoms must be detached from their original locations (perhaps at lattice points in a solid solution)‚ move through the surrounding material

attaches to the myosin head‚ it gets hydrolyzed to ADP and Pi. Calcium ions bind to the troponin molecules and help expose the binding sites of actin filaments to allow for the attachment of the myosin heads. After the sliding of the myofilaments occurs‚ a new ATP is required to unbind the cross bridge between the actin and myosin filaments. To test the response of muscle fiber to the addition of ATP and/or salts (KCl and MgCl2)‚ we conducted an experiment in which we added salts only‚ ATP only‚

Lunar eclipse [pic] [pic] The June 2011 total eclipse A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun‚ Earth‚ and Moon are aligned (in "syzygy") exactly‚ or very closely so‚ with the Earth in the middle. Hence‚ a lunar eclipse can only occur the night of a full moon. The type and length of an eclipse depend upon the Moon’s location relative to its orbital nodes. Unlike a solar eclipse‚ which can only be viewed from
