Which of the following scientist(s) was/were awarded the Nobel Prize in 1945 for the discovery of first antibiotic, extensively used to treat American soldiers wounded in World War II :
1 Alexander Fleming
2 Ernest Chain
3 Howard Florey
4 All of the above
Explanation:
Penicillin was the first antibiotic to be discovered from the mould Penicillium notatum. However, its full potential as an effective antibiotic was established much later by Ernest Chain and Howard Florey. This antibiotic was extensively used to treat American soldiers wounded in World War II. Fleming, Chain and Florey were awarded the Nobel Prize in 1945 , for this discovery.

The bottled fruit juices bought from the market are clearer than those made at home because :
1 They are double filtered
2 They are triple distilled
3 Clarified by the use of pectinases and proteases
4 Clarified by the use of amylases and hydrolases
Explanation:
Bottled fruit juices bought from the market are clearer as compared to those made at home. This is because the bottled juices are clarified by the use of pectinases and proteases.
