Arrange the following organisms in a correct sequence based on their formation during the course of evolution
(A) Chemoautotrophic organisms (B) Eukaryotes
(C) Anaerobic heterotrophs (D) Oxygenic autotrophic organisms

Q. Arrange the following organisms in a correct sequence based on chemical origin of life given by Oparin and Haldane during the course of evolution:
(A) Chemoautotrophic organisms
(B) Eukaryotes
(C) Anaerobic heterotrophs
(D) Oxygenic autotrophic organisms

Q. Arrange the following in proper sequence of their formation
A) Photo autotrophs
B) Anaerobic heterotrophs
C) Free genes
D) Chemo autotrophs

Q. Assertion :The earliest organisms that appeared on the earth were non-green and presumably anaerobes. Reason: The first autotrophic organisms were the chemoautotrophs that never released oxygen.

Q. Following are the two statements regarding the origin of life :
(1) The earliest organisms that appeared on the earth were non-green and presumably anaerobes.
(2) The first autotrophic organisms were the chemoautotrophs that never released oxygen.
Which one of the following options is correct?
