provide an example of how scientific knowledge has changed. be sure to discuss the reasons it changed. what was the impact made on society and/or the scientific community?

Explanation:

Let's take the discovery of penicillin as an example. Initially, bacterial infections were a major cause of death. Alexander Fleming's accidental discovery of penicillin (a mold - Penicillium notatum - that inhibited bacterial growth) in 1928 changed scientific knowledge. Before this, there were no effective antibiotics. The reason for the change was the need to combat deadly bacterial infections.

For society, it revolutionized medicine. It made previously life - threatening infections (like pneumonia, septicemia) treatable, reducing mortality rates, enabling safer surgeries (as post - operative infections could be controlled), and improving overall public health. For the scientific community, it spurred intense research into antibiotics, leading to the discovery of other antibiotics (like streptomycin, tetracycline) and the development of the field of microbiology and pharmacology. It also changed the way scientists approached the search for natural compounds with therapeutic properties, leading to more systematic screening of microbes and other natural sources for drugs.

Answer:

Example: Discovery of Penicillin. Reason for change: Need to combat deadly bacterial infections. Impact on society: Reduced mortality from bacterial infections, enabled safer surgeries, improved public health. Impact on scientific community: Spurred antibiotic research, advanced microbiology and pharmacology, changed drug - discovery approaches.
