Choose the correct answers from the alternatives given.
Many bacteria are now resistant to penicillin, because

  1. previously resistant forms survived and reproduced better than non-resistant forms

  2. penicillin triggers the synthesis of resistant proteins

  3. penicillin causes gene mutations, some of which are beneficial

  4. environment inhibits competition among bacteria
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Due to variation in bacteria some of them have resistance from penicillin. Penicillin largely use as killing bacteria but now bacteria develop immunity to penicillin. So bacteria with resistant gene from penicillin transferred character to offspring. 

Hence, the correct answer is 'previously resistant forms survived and reproduced better than non-resistant forms'

  2. radiometric dating

  3. variation

  4. typology
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Lamarck is best known for his "Theory of Inheritance of Acquired Characteristics", that is If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring. But according to Darwin, variation helps the species to survive in unfavourable condition environment.

So the correct option is C, variation.
