Compared with the RBCs, a 10% Na Cl solution is hypertonic while a 0.1 % Na Cl is hypotonic.

Since the latter solution is almost pure water, the blood cells are actually hypertonic by comparison.: Movement of water molecules from a region of high concentration to a region of lower concentration through a differentially permeable cell membrane.

Only one layer of cells is in focus when using the high power (40x) objective.

All that and more on this episode of NOVA science NOW! One of the reasons we're here, that we exist at all, is that Earth, cosmically speaking, is in a relatively peaceful place: orbiting our Sun in a near perfect circle.

Wednesday's statement says the chamber contains four canopic jars and a plate with hieroglyphic writings meant to protect the body.

We know that stars and planets, once upon a time, all started out like this, with enormous clouds of gas and dust. Some leave deep impacts in Earth, like one that blasted Arizona's Barringer Crater, 50,000 years ago. They can be as small as dice, reduced to a rocky cinder.
