Five test tubes were labelled with the appropriate SDS concentrations to be tested. 6ml of 0, 0. 025, 0. 05, 0. 25, and 0. 5 %SDS concentration were added to each appropriately labelled tube. A beet cylinder was then placed

As the title says, this movie is about the journey of man. Something incredible is that we all come from the same ancestors no matter what race we are. It informs every one of us of our beginnings and links

Diffusion is the movement of molecules or ions down a concentration gradient i. e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient, it should have a large surface area

There are three major parts of a cell– the nucleus, cytoplasm, and cell membrane, if these are stained appropriately, they can be easily seen under a light microscope. The nucleus (in many cell types) is the innermost and is enclosed

Epithelia form continuous sheets of cells that cover surfaces in our body. They are important in the formation of membranes which act as a barrier and interface between compartments of the body. Choose an area of the body covered by
