A simple stain is performed, but when the student looks under the microscope, individual organisms can’t be distinguished. What did the student do wrong when making the smear?Which of these given statements is inaccurate about bacterial endospores? Question 12 options: Sporulation helps all bacterial species to survive. Clostridium species can form endospores. Endospores can resist harsh environments. Endospores germinate in favorable environments.
- Need help In a micro lab there are various staining procedures, different microscopes, and media that are used to grow, test, and view microbes. Imagine you are a microbiologist explaining an aspect of the prokaryote and how to work with it in the lab. The options for discussion are endless, its just a matter of tying the two topics together. For example: for an acid fast cell wall requires a specialized stain, and then a microscope to view.Helping tags: Biology, yeast, food, microbiology, food microbiology, vinegar . . . If the steps involving yeast inoculation are not done, what would happen to the process of vinegar making? Would you still be able to produce vinegar? Explain your answer. . . . WILL UPVOTE, just please help me answer the question. Thank you.1. why is there a need to incubate cultures at room temperature? How can this affect microbes? 2. Explain why an inverted image is seen under a compound microscope.
