Explanation / Answer

13. In transduction, the bacteria takes place and get diversity with the help of process known as recombination. Hence, option C is correct .

14. Correct sequence of developmental stage of plsmodium is

starting from sporozyte and ending with oocyte. Hence, option B is correct .

19. Since, both slime moulds and yeast have originated from a single ancestor they are known as homology. Hence, option E is correct .
