Explanation / Answer

27. According to endosymbiotic theory, the eukaryotes organelles have originated from prokaryotes that is from both purple sulfur bacteria and cyanobacteria. Hence, c is true statement.

28. Incorrect statement is plants are the primary photosynthetic organisms not algae. Hence, a is incorrect statement.

29. Extinction only affect weak and old lineages. This is false statement.

30.In the early earth, carbon dioxide concentration was much high than today. This is false statement.

31. Planetary killer is human according to Wilson. Hence, C is correct.

32. Local sesimic disruption and earthquake are not the correlated with hydraulic fracturing. Hence, c is incorrect.

34. Hominids have originated in Africa. Hence, C is correct.
