Laboratory 4 Pre Lab Questions Pdf Laboratory 4 P Lab 4: gel electrophoresis 7 pre lab questions read through the entire protocol and answer the questions below. 1. assume that single pcr reactions were loaded into two separate gels for arthropod and wolbachia dna analysis. fill in the expected bands for lanes 2 7 using the table below. 2. this experiment included five controls. Pre lab questions. compare and contrast diffusion and osmosis. osmosis is the process of solvent traveling from a dilute solution to a concentrated solution to equalize the concentration; diffusion is the process of particles moving from an area of high concentration to an area of lower concentration to equalize the concentration.
Week 4 Pre Lab Questions Pdf Lab 3 Stoichiometry And Chemical Give an advantage of dark field or phase contrast microscopy over bright field. parts of the compound microscope. label the parts of the microscope indicated by the arrows: contributors and attributions. kelly c. burke (college of the canyons) this page titled 3.3: pre lab questions is shared under a cc by license and was authored, remixed, and. Lab 4 pre lab questions: 1.) a chemist prepares a 0.50 m solution of naf which gives a measured ph of 8.58; and also prepares a 0.50 m solution of nh 4 cl which gives a measured ph of 4.78. write net ionic equations consistent with each of these observations: 2.) what is the conjugate base of the acid, nh 4 ? what is the pka of nh 4 ? 3 3 4. Next, answer the following questions about the lab: 1. what are you supposed to be learning about by doing the lab? the goal of this lab is to help you learn about a scientific concept (principle, theory, law) or about a laboratory procedure. based on your reading of the lab materials, identify the scientific concept and or lab procedure you. Pre lab 4: osmosis and diffusion. get a hint. diffusion. the net movement of molecules, or ions, from an area of high concentration to an area of low concentration. simple. the movement of solutes through a semipermeable membrane. 1 37.
