An example of the use of acid-fast staining is the staining of bacteria that have mycolic acids in their membrane, also called acid-fast bacteria because they resist unstaining with this acid-alcohol mixture. Because of this characteristic, such bacteria are not gram-stained. Therefore, B is not the answer.

To perform this staining you must first make a smear of the bacteria and fix it on the slide and then stain it. The immersion in acid alcohol is done during the staining process and the observation under the immersion lens at the end of the staining. Therefore, the answer is C

Is this telophase of cytokinesis?
Butoxors [25]
Looking at the inside, it appears so.

In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.

Hope this is correct ^^

Why is the hypothesis that black cats cause bad luck not science?
Alja [10]

Because it has no scientific explanation. As a matter of fact it has no explanation.

The things that black cats cause bad luck are a myth, and do not have any proof or explanation, meaning it cannot be concluded neither as a hypothesis nor scientific.


Hope it helped,
