Counterstains are chosen to be contrasting colors so that the primary satin target can be easily distinguished from the contrasting background.

<h3>What is counterstain?</h3>

A counterstain is a stain that contrasts with the primary stain, making the stained structure visible under a microscope.
A counterstain is a color that is introduced into specific cellular structures in order to create a contrast to the colored enzyme substrate.
Counterstaining improves vision and target localization, allowing for a more accurate assessment of morphology and cell organization within a tissue section.
Counterstains are intended to be opposing colors in order for the principal satin target to stand out against the contrasting background.
The counterstain utilized in this procedure is Safranin.
Gram staining is used to differentiate Gram-positive from Gram-negative bacteria.

Therefore, counterstains are chosen to be contrasting colors so that the primary satin target can be easily distinguished from the contrasting background.

I am Lyosha [343]

Answer:

The dependent variable is their degree of sleepiness.

Explanation:

In a correlational study, an independent variable is expected to affect a dependent variable. In the example, the level of caffeine intake is predicted to change the participants' sleep patterns. In other words, the degree of sleepiness <u>depends</u> on the caffeine levels.

An easy way to remember the difference is to say: Independent causes change in dependent.

Why is deposition as the opposite of erosion? Give examples of these processes.

klio [65]

<u>Answer:</u>

Deposition is a "conservative" while erosion is a "destructive" mechanism.

<u>Explanation:</u>

Deposition is when the surface is exposed to sediments, dirt, or rocks. It's the inverse of erosion. Deposition is a positive method since it builds or produces surface features. As over time wind, water and other forces will wear away sediments, so must sediments be accumulated as well. The process through which water vapor transforms spontaneously to ice in sub-freezing air, without first becoming a liquid is one of the instance of deposition.

In earth science, erosion is the activity of surface mechanisms that detach soil, rock, or soluble material from one place on the crust of the Earth, and then transferred it to another. For an instance wind carries away small pieces of rock from a mountain side.
