A researcher has three different stains that differentiate between keratin, actin, and tubulin when the cells are fixed and stained for microscopic analysis. Which of these stains will the researcher be able to use to study cytoskeletal structures that are stable and do not have the property of dynamic instability

Acti-stain => They are stable and do not have the property of dynamic instability.

Explanation:

There are different types of stains in the world of science (biological sciences) today. Staining is used to make differentiation between two or more different samples(microbiology).

So, in organisms that has a well defined nucleus we can find actin, keratin and Tubulin in their cytoskeleton as fibres. The staining process or techniques can be used in differentiating them.

Actin can be found in the cells located in the muscles and also very useful in motility.

Acti-stain for instance, acti-stain 488 was used in staining yeast cells and they are stable and whenever they stain, they are fixed.

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.
