Question

Which of the following helps early protobionts to evolve into living cells?

• A. A semipermeable membrane and a nucleus
• B. Competition for resources and the development of hereditary mechanisms
• C. A semipermeable membrane and the ability to catalyze chemical reactions
• D. A nucleus and the ability to catalyze chemical reactions
• E. A mechanism for growth and a mechanism for asexual reproduction

Answer 1

Answer: (B)

Competition for resources and the development of hereditary mechanisms

Competition for resources and the development of hereditary mechanisms helps early protobionts to evolves into living cells. A thin limiting membrane was developed around the cytoplasm by the folding of a monolayer of phospholipids to form cell-membrane. These are precursors for the early life which evolved into a living cell. The organic and inorganic molecules present in the protobionts, later on, develops into the genetic material which acts as a carrier of hereditary characters.

So, the correct answer is option B.
