pH indicating dyes
Yes, Enterobacter cloacae is capable of producing hydrogen sulfide (H2S) as part of its metabolic activity, which can be detected through biochemical tests such as Triple Sugar Iron (TSI) agar.
A region where a magnetic force can be detected is typically within the magnetic field surrounding a magnet or an electric current. This field extends outwards from the source of the magnetism and can be detected using tools such as a magnetic compass or sensitive electronic instruments.
If something is detected, it means it was discovered or had its existence identified (If cancer is detected early on, it is easier to cure).
BV can't be detected by a urine test. BV is found physical exam, pH testing of the vaginal fluid, or microscopic exam of the fluid, or a combination of these.
Body fluids such as semen, urine, saliva, and blood can be detected by a black light due to their fluorescent properties. These fluids will typically glow brightly under a black light, making them visible even in low light conditions.
It depends on what you mean by "transmit". Our nerves and muscles use electrical signals. These signals can be detected outside the body. The biochemical processes in each cell uses energy. This energy can be detected outside the body as heat.
Stearyl and cetyl alcohol are common cosmetic ingredients that are unlikely to be detected by a SCRAM bracelet, which is typically designed to detect alcohol consumption through sweat. These alcohols are not the type that are typically associated with intoxication.
Although psilocybin is not typically tested for, it can be detected in a urinalysis.
No. There is a blood test, but it is expensive and typically used if death results.
Yes, Enterobacter cloacae is capable of producing hydrogen sulfide (H2S) as part of its metabolic activity, which can be detected through biochemical tests such as Triple Sugar Iron (TSI) agar.
The process by which light is detected by the human eye and converted to an image is a serious of energy changes. Light is the first energy which causes chemical reactions. These reactions are then changed to electrical energy signals which are sent to the brains through the optical nerve.
No, Visine typically contains tetrahydrozoline which is unlikely to be detected in routine blood tests. However, specific toxicology or drug screening tests may be able to detect its presence.
The disease is typically detected in middle age, after age 50.
Stimuli are detected by the nose through specialized sensory cells called olfactory receptors located in the olfactory epithelium. When odor molecules bind to these receptors, they trigger a biochemical response that generates electrical signals. These signals are then transmitted to the olfactory bulb in the brain, where they are processed and interpreted as specific smells. This complex process allows us to perceive and differentiate a wide array of odors.
Yes, inhalants can be detected in drug tests, but they are not typically included in standard drug screenings. Specific tests can detect the presence of inhalants in urine, blood, or hair samples if requested.
A region where a magnetic force can be detected is typically within the magnetic field surrounding a magnet or an electric current. This field extends outwards from the source of the magnetism and can be detected using tools such as a magnetic compass or sensitive electronic instruments.
Gases produced during fermentation reactions can be detected using techniques such as gas chromatography, gas sensors, or gas collection followed by analysis. Gas chromatography separates and quantifies different gases produced, while gas sensors can detect the presence of specific gases based on changes in electrical conductivity. Gas collection allows for direct measurements of gas volume or composition.
