What is a positive test for catalase? 6. What substrate is used to test for the presence of the Coagulase enzyme? What does Coagulase do for a bacteria that has it?
var gArr = [ {food: 'apple', type: 'fruit'}, {food: 'potato', type: 'vegetable'}, {food: 'banana', type: 'fruit'} ]; How do I add to the array above via user input using javascript code? For example if the user entered 'orange', I want to add to the array like this {food: 'orange', type: 'fruit'}.
An enzyme, encoded by gene A, converts substrate X into product Y. Individuals with a dominant mutation in gene A over accumulate substrate X, which causes severe neurological symptoms. At the molecular level, this enzyme functions as a homodimer. A homodimer is a protein composed of two subunits that are encoded by the same gene. Let’s suppose you are able to purify subunits from cell samples and then mix them together under conditions in which they form homodimers, and you...

4. What reaction would you expect when performing a positive control in the oxidase assay? What would it mean if a known oxidase-positive bacterium did not cause the expected reaction?
1. A sample of fresh banana is dried to remove all water. The dried banana weighs 3.0g. This 3.0g sample is burned and the final ash weight is 1.0g. If 83% of fresh banana tissue is water: a. What was teh original wet weight of the 3.0 gram sample of dried banana? Show your work. b. When the dried sample of banana was burned, what became of the organic molecules that made up the banana tissue? c. When the dried...
13. If a banana is available, scrape a small amount of tissue from its surface and spread it onto a slide. Add a drop of Lugol's solution and a coverslip. Observe the preparation using high power (40x) f. How do these observations compare with what you saw in the potato? 2. Use a razor blade to slide a piece of tissue, as thin as possible, from the outer portion peeled carrot. Prepare a wet-mount slide. g. Can you see the...
