Part I: Pre-Lab Diffusion/Osmosis Pre-Lab Introduction: Dialysis tubing allows molecules to diffuse through microscopic pores in the tubing. Molecules that are smaller than the pores can diffuse through the dialysis membrane along the concentration gradients. Molecules that are larger than the pore size are prevented from crossing the dialysis membrane. Answer questions in complete sentences. For problems‚ show equations and work with units and appropriate significant figures. Part IA: In the following

muscle contraction Introduction For a skeletal muscle fiber to contract‚ a stimulus must be applied to it. The stimulus is delivered by a nerve cell‚ or neuron. A neuron has a threadlike process called and axon that my run 91 cm or more to a muscle. A bundle of such fibers from man different neurons composes a nerve. A neuron that stimulates muscle tissue is called a motor neuron. The motor neuron branches into terminal structures called telodendria that come into close approximation with

Microbiology Lab Quiz #2 Study Guide Exercise 9 -- The Gram Stain Compare and contrast simple and differential staining techniques. Simple Staining Simple staining is useful in determining the basic morphology of an organism. Simple staining involves only one reagent i.e. crystal violet‚ basic fuchsin‚ or methylene blue. Simple dyes used to stain bacteria have a positive charge cationic (+)‚ therefore‚ they are attracted to the bacteria that are usually negatively charged anionic (-) Depends
