crashed in a nearby field. you and some other physiology students collect samples from
the beings inside of the spaceship. first, you collect a liquid sample of what appears to

cells. you then extract some of these cells, place them in various concentrations of
glucose in water, then look at them under the microscope. below is what happens to the
cells when they are placed in various concentrations of glucose:
table 5.1
refer to table 5.1. how can you determine the osmolarity and tonicity of the alien blood
and alien cells?

4) the center of an atom is called the ________.

as skeletal muscle. why is kevin’s choice wrong, and what tissue is he probably
observing?
