Question

Exobiology is connected with study of
(a)Life in air
(b)Terrestrial organisms
(c)Exodermis
(d)Life on other planets

Answer 1

Hint: The science of exobiology tries to reconstruct the explanation of processes and incidents involved within the transformations of the biogenic elements from their origins in nucleosynthesis to their participation in Darwinian evolution in the solar system on planet Earth.

Complete answer:
Exobiology is connected with study of life on other planets. The goal of exobiology is to extend knowledge of the origin, evolution, and distribution of life within the universe. It specializes in the search for and study of life elsewhere in the universe. This is a multidisciplinary science, and the conceptual and experimental tools of virtually all scientific disciplines and branches of learning are relevant. In seeking answers to such questions as how the development of the solar system and its planets led to the origin of life on Earth, how planetary evolution subsequently influenced the course of biological evolution, and where else life may be found in the solar system and beyond, exobiology brings together life scientists and physical scientists in a common interest.

Additional Information: Exobiology is concerned with four evolutionary epochs which are-
-Cosmic evolution of biogenic elements and compounds
-Prebiotic evolution
-Early evolution of life
-Evolution of advanced life.
Each of those epochs, briefly described below, represents a serious arena of research. Between now and the mid-1990s, the task group expects this conceptual framework to become widely acknowledged and to act as a stimulus for interdisciplinary attacks on exobiological research problems.
So, the correct answer is ‘Life on other planets’.

Note: Exobiology is also called Space biology or Astrobiology. The term exobiology was coined by biologist and Nobel Prize winner Joshua Lederberg. Exobiology is considered to have a narrow scope limited to search of life external to Earth.
