Doing so will ensure that the carbohydrates substrates have not benn depleted and that deradation of peptones yielding alkaline end products has not taken place.
TSI (triple sugar iron) test observations are made 18 to 24 hours after incubation because this time frame allows for the characteristic reactions to occur. The test is designed to differentiate between bacteria that can ferment glucose, lactose, and/or sucrose and produce acid and gas. Observing the reactions within this time frame ensures accurate interpretation of the test results.
hours are made up of minutes
create a scenario where in inference can be made from several observations
observations r made with the five senses (feel, taste, hear, sight, and smell).
Observations are records of occurrences and details, and are made in the course of an investigation or experiment.
He made many experiments and observations in the field of physics in general.
the first observations of the solar system were made by the mayans
Pythagoras Galileo was the person who made the first famous observations with a telescope.
Measurement
Objective observations are observations that are made based on facts and measurable data, free from personal bias or interpretation. They are observations that can be confirmed or validated by multiple individuals and are not influenced by personal opinions or feelings.
With an observation, you simply take note of your surroundings or what you happen to notice. In an inference on the other hand, the observations are then analyzed and a conclusion is made.
A vaccineIt's called inoculation. Inoculation is defined as: the placement or insertion of something (micro-organism) which will grow or reproduce. It is most commonly used in the introduction of vaccinations, serums and antigenic substances.
