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.

Reasons why a smear from a gram-positive control showed a gram-negative result?
Possible reasons for a gram-positive control smear showing a gram-negative result could include errors in the staining process, contamination of the specimen with gram-negative bacteria, or misidentification of the control as a gram-positive organism when it is actually gram-negative. Additional troubleshooting and repeat testing may be needed to confirm the result.
What is a prokaryotic organism?
An organism that's lacks a nuclear membrane. It doesn't have a true nucleus.
What does an organism scientific name include?
An organism's scientific name includes its genus and species. It is written in italics, with the genus capitalized and the species lowercase, and together forms the organism's unique scientific identifier.
What is an organism called with only one cell?
An organism made up of only one cell is called a unicellular organism. Examples include bacteria and protozoa. These organisms carry out all the functions of life within a single cell.
What is an organsim that live inside or an another organism?
An organism that lives inside another organism is known as a parasite. Parasites obtain nutrients and shelter from the host organism, often causing harm or disease in the process. Examples include tapeworms, ticks, and some bacteria.
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.
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.
Reasons why a smear from a gram-positive control showed a gram-negative result?
Possible reasons for a gram-positive control smear showing a gram-negative result could include errors in the staining process, contamination of the specimen with gram-negative bacteria, or misidentification of the control as a gram-positive organism when it is actually gram-negative. Additional troubleshooting and repeat testing may be needed to confirm the result.
What are 4 type of mutation?
Four types of chromosomal mutations include substitution, insertion, deletion, and frame shift. These mutations can be either positive of negative to the organism.
What are fratricide prevention techniques?
Fratricide prevention techniques include situational awareness, positive target identification, effective fire control.
What is positive organisms?
"Positive organisms" is a term that typically refers to microbes that have beneficial effects on their environment, such as by promoting health or growth in plants, animals, or humans. Examples include probiotic bacteria in the gut that aid in digestion or nitrogen-fixing bacteria in soil that enhance plant growth.
Why a scientist include a control an experiment?
A control can either provide a baseline, show that the experiment is specific for the variable or show that the experimental procedure works. So if you want to determine if having more enzyme degrades sugar faster you include a control that you know will degrade sugar at a certain rate. Then you compare what happens in the control and in your sample with more enzyme you can see if your hypothesis is correct. When multiplying DNA by PCR one often uses a negative control (an organism without the gene and/or water) to show that you only multiply what you think you are multiplying and a positive control (a previously isolated piece of the DNA) to show that the PCR was successful even if none of the other samples amplified a fragment.
How can transgenic organism effect you?
Transgenic organisms can have both positive and negative effects on humans. Positive effects include increased crop yields, improved nutrition, and potential for medical breakthroughs. Negative effects can include environmental concerns, such as cross-breeding with wild populations, and potential health risks if the transgene produces allergenic proteins.
What does micro organism include?
the micro-organism cell includes fungi,protozoa,viruses,bacteria and algae
What Ecological cycles include of organism?
seasonal behavior
Which micro-organism causes ringworm?
Micro-organism's that cause ringworm include the three genera of fungi Trichophyton, Epidermophyton, and Microsporum. Micro-organism's that cause ringworm include the three genera of fungi Trichophyton, Epidermophyton, and Microsporum.
Biological factors that affect an organism's niche include all what except what?
Biological factors that affect an organism's niche include its diet, predators, competitors, and physical attributes. Non-biological factors that can also affect an organism's niche include abiotic factors such as temperature, habitat structure, and availability of resources.
