To collect impressions found in dust, scientists use a device that:

vacuums the dust up evenly onto a clear, sticky film.
B.
uses a negative charge to create an image on a plastic-coated metal sheet.
C.
uses extremely low-density, quick-hardening foam to fill the spaces.
D.
Impressions can’t be collected from dust.
A. vacuums the dust up evenly onto a clear, sticky film.
Color, texture, and presence of vegetation or animal material all can help identify/classify what type of material?
A.
chemicals
B.

C.

D. soil.
Dorothy’s brother, Paul, was recently arrested for stealing money from the company where he worked. Police question her and she becomes belligerent and uncooperative claiming that she doesn’t have to answer any questions until they read her the Miranda rights. The police remind her that this is NOT true because:
A.
she is not in formal custody.
B.
she is related to the suspect.
C.
she is a woman.
D.
she is a lawyer.
B. she is related to the suspect.
To answer this question, we need to assess each option and determine which one describes the process of collecting impressions found in dust.
Option A suggests that scientists use a device that vacuums the dust up evenly onto a clear, sticky film. This mechanism would allow the dust particles to stick to the film and form impressions.
Option B proposes that a device uses a negative charge to create an image on a plastic-coated metal sheet. While this method may be used to create images, it does not specifically mention collecting impressions from dust.
Option C suggests the use of extremely low-density, quick-hardening foam to fill the spaces. Although this technique might be used in other processes, it does not pertain to collecting impressions from dust.
Option D claims that impressions cannot be collected from dust. This option contradicts the question itself, which assumes that scientists collect impressions found in dust.
By process of elimination, option A, "vacuums the dust up evenly onto a clear, sticky film," is the most plausible choice. Thus, the correct answer is A.
