You can do an experiment to determine motility. You use a medium of agar that has tetrazolium salt (TTC). The TTC serves as a terminal electron acceptor for the bacteria and turns the medium red. You would inoculate a needle with your bacteria and put it straight into the media and straight out. After incubating your bacteria, if you see the red move away from where you inserted the needle, then it would indicate that your bacteria is motile. If the red is only in the place where you inserted the needle, then it is not motile.
No, motility cannot be determined using the Gram stain technique. The Gram stain method is primarily used to differentiate bacteria based on their cell wall composition (Gram-positive or Gram-negative) and does not provide information on motility. Motility is typically assessed through techniques such as microscopy, agar stab, or hanging drop methods.
Common media used to determine motility and growth patterns of bacteria include agar-based media such as nutrient agar, motility agar, or semisolid agar. These media allow for observing colony morphology, motility (through diffusion in semisolid agar), and growth patterns (e.g., pellicle formation). Additionally, specialized media like SIM (sulfide-indole-motility) agar can be used to detect hydrogen sulfide production, indole production, and motility of specific bacteria.
The apparatus used in Linds method is a crucible and lid, which are used to heat a sample to high temperatures in order to determine the moisture and volatile content.

Motility refers to the ability of an organism or cell to move spontaneously. It is often used in the context of biology to describe the movement of cells, such as sperm cells swimming or bacteria moving. In a medical context, motility can be used to assess the functionality of organs like the intestines or muscles.
There are two basic method to determine motility in a bacterial sample. These samples have similar biochemical identifiers. The first test is a simple drop test. The second method employs a motility medium

Hangng drop method is used for bacterial examination of fresh preparations-- meaning those which are alive so you can observe their motility, its usually true motility or the brownian movement. This is accomplished by having a drop of liquid preparation into a concave slide with its circular sides filled with vaseline to prevent evaporation. then a cover slip is applied. I dunno what you mean by your question by " other organisms" obviously you can only apply it to bacteria. examples like Staphylococcus aureus, G. tetragena or P. vulgaris.

a method designed to determine if two or more variables are associated with each other. descriptive method is used to describe the present behaviour or characteristics of a particular population.
