How can you tell from OF-glucose medium whether an organism oxidizes glucose?

If it uses glucose regularly the organisms will produce acid in the open tube only and the indicator will turn yellow. If carbohydrates are metabolized in both tubes, fermentation has occurred. There will be a dark blue color.

If an organism oxidizes glucose in an OF-glucose medium, it will use up the available oxygen in the aerobic tube first before moving into the anaerobic tube. This results in a color change in the medium due to the pH indicator, showing alkaline conditions in the aerobic tube and acidic conditions in the anaerobic tube.

Does chromosome number indicate whether an organism is a plant or animal?
no
What test should be done to test whether a sample contains glucose?
Benedict's
Does chromosome number appear to correlate to the type of organism?
No. Just number of chromosomes cannot indicate whether the organism is a plant or an animal.
Whether a plant is an organ or tissue?
A plant is neither an organ or a tissue, it is an organism!
Which type of media would be best to determine whether or not an organism is motile?
A video recording would be the best type of media to determine whether an organism is motile because it can capture the movement and behavior of the organism in real time, providing a more accurate assessment of its motility compared to images or text descriptions.
What does a karyotype reveals?
It can reveal the sex (gender) of an organism. It can also reveal whether the organism has the correct number of chromosomes or not.
Does chromosome number indicate whether an organism is a plant or animal?
no
What does food provide for organism?
Food privdes all the nutrients that help an organism to: -grow -stay healthy -repair tissues(in animals) or damaged parts of their "body" easily, whether it is a bacteria, a plant, or an animal. Food also helps with respiration, especially glucose, which gets oxidised and is turned into carbon dioxide, which is excreted from the body in any for more oxygen.

How can you determine whether a unicellular organism is a prokaryotes or a eukaryotes?
A prokaryotic organism lacks a nucleus to hold its genetic information. A eukaryotic organism has a distinct nucleus. The two can be distinguished by microscopic investigation.
How would a scientist tell whether an organism was a vertebrate or not?
By using a x-ray
Whether a plant is an organ or tissue?
A plant is neither an organ or a tissue, it is an organism!
A student observes that an organism is green A valid conclusion that can be drawn from this observation is that?
4 ..not enough information is given to determine whether the organism is a plant or an animal
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.
