Explanation / Answer

55.55)

The fact that marsupials are not as diverse in South America as they are in Australia would be classified based on the molecular evidence.

56)

The hypothesis that states that the very first living thing came from nonliving chemicals is the hypothesis of chemical evolution.

57)

The structures necessary for the replication process in a cell are the enzymatic proteins.

58)

The flipper of a whale and wing of a bird are homologouys structures - True.

59)

Both the RNA-first and the protein-first hypotheses must propose a manner for DNA to become the genetic material as it is today - is true.

60)

The early atmosphere of Earth consisted mainly of water vapor, hydrogen, and carbon dioxide.

61)

Phosphorus cycle is biogeochemical cycle, is a sedimentary cycle.

62)

The temperature and the rainfall are the characteristics that define the biome.

63)

The atmosphere is considered as the abiotic component of biogeochemical cycles. Hence, the option is none of these.

64)

Yes. Humans capable of upsetting global biogeochemical cycles with their activities.

65)

The richest marine ecosystems are those in the open water where large fish abound is false.

66)

Conversion of nitrate to nitrogen gas is the process involved in the denitrification.

67)

Loss of water from plants is called as transpiration.
