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

Unknown Organism Report Unknown Organism # 4 Klebsiella pneumonia Klebsiella pneumonia has a rod gram stain with the agar slant cultural characteristics being slimy‚ white‚ somewhat translucent‚ raised growth. It is small gram-negative coccobacilli that can cause lobar pneumonia. The litmus milk reaction is acid‚ gas‚ and curd with a variable reaction. Klebsiella can grow either in the presence or absence of oxygen because of its nature of being a facultative anaerobe. Oxygen is a preferred energy

1. A functional cell could be built with a single chromosome‚cytoplasm‚a cell membrane‚ and ribosomes.Why are these four components absolutely necessary to the functional cell? If these structures are all a cell needs‚ why do most cells have many more structures? A chromosome is necessary so that there is a “map” of the cells function and structure‚ cytoplasm is necessary as it is where most of the cell’s activity occurs‚ ribosomes are essential as they are the site of protein synthesis‚ which

Submitted: June 6‚ 2012 Name: 2968 Instructor: Reid A hydrate was given to our group and the identity of the hydrate was unknown. The lab workers were told to determine the identity of the unknown hydrate. The identity of the hydrate could be determined by calculating the hydrate’s percent of water. So the lab workers set out to determine the water percent of the unknown hydrate. The percent of any compound or element can be found by using a certain formula. This formula is: % of element = Mass

Melting-Point Measurement Organic Chemistry Lab Introduction: Panacetin purportedly includes sucrose‚ aspirin‚ and acetaminophen. However‚ the accuracy of Panacetin’s contents has been called into question by the Association for Safe Pharmaceuticals. Therefore‚ the lab must discover the accuracy of the ingredients listed on Panacetin’s label. The unknown in this experiment is presumed to be something similar to acetaminophen‚ such as acetanilide
