How sterile is contact lens solution and how long does it stay sterile? see how long it takes for mold, fungi, and bacteria to culture saline. for that matter, how sterile is the inside of a person's contact lens case?

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
