BOT3015 EXAM 3 Marking Scheme 2024 100% Correct Brownian movement - Answer- molecules /ions in constant random motion Diffusion - Answer- movement of molecules or ions from region of higher concentration to region of lower concentration Molecules that are moving from a region of higher concentration to a region of lower concentration are said to be moving ______________________________ - Answer- Along a diffusion gradient molecules moving from regions of low to high concentration are sai...

*Negative Staining* Procedure - 1. Add a droplet of water 2. Using an aseptic technique, place a loopful of the microorganism from the culture in the droplet and mix 3. Place another slide at a 45° angle in a drop of nigrosin at the edge of the slide with mix 4. Push or pull the slide over the the mix to form thin layer over. Leave to air dry Bacillus (Bacilli pl.) - *Rod* shaped bacteria Because of a snowstorm, your regular laboratory session was canceled and the Gram staining procedure...

Gram positive bacteria do not retain CV when gram stained, so they appear pink after counter-staining with safranin. T/F - False. They do retain crystal violet and appear purple Complex media is made with precise chemical composition. T/F - False. Complex media has unknown composition ______ is an opportunistic pathogen that causes staph infections. - Staphylococcus aureus A durham tube is included in the LT broth tubes to detect _________, a byproduct of lactose fermentation - gas product...

How does temperature influence diffusion?as temperature increases, the time of diffusion increases. heat increases the influence on Brownian motion of molecules and will make them move much faster. as they move faster, they distribute faster. How might the application of heat/ice to an injured body part relate to the above concept in the body?applying ice to a body part decreases the movement of fluid/solutes, therefore reducing the amount of swelling. heat, on the other hand, will increase the...
