When bacteria are grown in broths such as trypticase soy broth (TSB), they may exhibit patterns of growth ranging from a sediment at the bottom of the tube, turbid growth throughout the tube, or a pellicle (thick growth at the top of the tube).

Why are cells allowed to swim into and out of the loop's water film rather than scraping the agar surface of growth and then emulsifying cells on the slide?

The ability of cells being allowed to swim into and out of the loop's water film rather than scraping the agar surface of growth and then emulsifying cells on the slide is due to its morphology. The path chosen is due to the cell's make up.


What is it called when water molecules are stuck so tightly together that they form a film that can support the weight of an insect?

Surface tension.


You notice a thin film of insoluble solid floating on the surface if the pools water what type of reaction what would floating film be called?

The thin film of insoluble solid floating on the surface of the pool water is likely the result of a precipitation reaction, where two soluble substances react to form an insoluble product. This floating film is called a precipitate. Such reactions typically occur when ions in solution combine to form a compound that is not soluble in water, causing it to aggregate and float on the surface.


What is the proctective film that gives skin its slight acidity?

The protective film that gives skin its slight acidity is called the acid mantle. It is a thin, slightly acidic film on the surface of the skin that helps to protect against harmful bacteria and maintain skin health.


Why does oil or soap film when in daylight appears coloured?

Oil or soap films appear colored in daylight due to a phenomenon called thin-film interference. When light waves hit the film, some are reflected off the top surface while others penetrate the film, reflect off the bottom surface, and then exit. These reflected waves can interfere with each other—constructively or destructively—depending on their path length, causing certain wavelengths (colors) of light to be amplified or canceled. This results in the vibrant, shifting colors we see in the film.

What is the sensitive surface of the eye that acts like the film in a camera?

The retina is the sensitive surface of the eye that acts like the film in a camera. It contains specialized cells called photoreceptors that convert light into electrical signals, which are then transmitted to the brain for visual processing.


What is the Skin on a film of water called?

The skin on a film of water is called surface tension. It is caused by the cohesive forces between water molecules.
