Physics Domino Lab I. Problem: What spacing between the Domino’s will provide the fastest velocity for a line of falling Domino’s. II. Background: The Domino C.I.M. lab that we have been assigned brings forth the question of the compression of a line of Domino’s. The question is‚ what set up of Domino’s has the fastest compression time. We intend on testing this by lining up different strings of Domino’s and finding which variable of distance has the greatest compression velocity

diffused at a higher temperature. Temperature can also affect the rate of diffusion because a higher temperature will cause molecules to move faster and increase the rate of diffusion‚ allowing more pigment to pass through the membrane‚ in the 5 minutes given‚ giving a more pink/red color to the water surrounding the beetroot at a higher temperature‚ and at lower temperatures slowing down the molecules and making the rates of diffusion lower in colder temperatures‚ giving it a paler appearance. This explains

Virtual Lab Unit 3 1. Briefly describe the steps required to aseptically transfer bacteria from an unknown to a tube of liquid broth. You might have to research this using the "T" button (Tell Me More About...) To aseptically transfer bacteria from an unknown to a tube of liquid broth you have to flame the loop or wire before you begin to sterilize it. You then remove the caps from the tubes and flame the mouths of the tubes to prevent air-borne contamination. When all this is done‚ you have to

Saliva Lab Since the amylase enzyme is present in saliva‚ starch digestion begins in the mouth. Salivary amylase changes the polysaccharide starch into many disaccharide molecules of maltase (a simple sugar) which are further broken down into glucose units by maltase enzyme in the As stated above‚ saliva contains the amylase enzyme which begins the breakdown of starches. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under
