What type of organism was added to a test tube when o2 increased over time?
green alga :)
What indicates a test for catalase production is positive?
A positive catalase test result is indicated by the presence of bubbles or effervescence when hydrogen peroxide is added to the test organism. This indicates the production of the enzyme catalase, which breaks down hydrogen peroxide into water and oxygen gas.
Why is it advisable to include a known oxidase-positive control in any test of an unknown organism?
Including an oxidase-positive control in a test of an unknown organism helps to confirm the presence of the enzyme oxidase in the test system. This control provides a baseline for comparison with the unknown organism to determine if it also produces oxidase. This is particularly important in biochemical testing to accurately identify the unknown organism based on its metabolic properties.
What cross should a scientist perform in order to determine if the organism is heterozygous or homozygous dominant?
The scientist should perform a test cross between the organism and a homozygous recessive organism. If all offspring show the dominant trait, the original organism is homozygous dominant. If some offspring show the recessive trait, the original organism is heterozygous.
Why is important to inoculate a single tube per organism when performing a MRVP test?
Inoculating a single tube per organism ensures that the test results are specific to that particular organism. Mixing multiple organisms in one tube can lead to inaccurate results due to potential interactions or competition between the different organisms during the test. Keeping the organisms separate helps to maintain the test's reliability and accuracy.
An organism was added to a test tube containing water which was then sealed and placed in sunlight The test tube showed what type of organism was added an increase in oxygen over a period of time?
The organism added was likely a photosynthetic organism, such as algae or a plant. Photosynthetic organisms use sunlight to convert carbon dioxide and water into oxygen during photosynthesis. The increase in oxygen observed in the test tube is a result of this process taking place.
An organism was added to a test tube containing water which was then sealed and placed in sunlight The test tube showed what type of organism was added an increase in oxygen over a period of timeW?
The organism added to the test tube was likely a photosynthetic organism, such as algae or a plant, that produces oxygen through photosynthesis in the presence of sunlight. The increase in oxygen observed over time is a result of this photosynthetic process where the organism uses sunlight to convert carbon dioxide and water into oxygen and glucose.

What is a UDRL blood test?
Most probably its VDRL test.
What do the initials VAT stand for?
For most people, the initials VAT are probably understood to mean "Value Added Tax" However in another context, they can mean "vitro-acousitc test."
If you drink on Tuesday night will it show in a drug test on Thursday night?
Most drug test do not test for alcohol.... but if you are talking about a brethalizer: probably not.
Why has your car failed the emissions test?
The catalytic converter is most probably broken
How does QVC drug test for employment?
Probably, all most every employer does.

A positive catalase test result is indicated by the presence of bubbles or effervescence when hydrogen peroxide is added to the test organism. This indicates the production of the enzyme catalase, which breaks down hydrogen peroxide into water and oxygen gas.
Why is it avisable to perform test of unknown catalase positive organism along with the organism you are testing?
you need to test both the experiment-organism and an organism which you already know is catalase-positive, in the same environment in order to compare the results and determine if your experiment-organism is catalase-positive. - See more at: http://www.chacha.com/question/why-is-it-advisable-to-perform-a-catalase-test-on-a-known-catalase%26%2345%3Bpositive-organism-along-with-the-organism-you-are-testing#sthash.oChX8ZqW.dpuf
Why is it advisable to include an oxidase-positive control organism in any test of an unknown organism?
It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.
