From his experiments, S.L. Miller produced amino acids by mixing the following in a closed flask
1 \(\mathrm{CH}_{3}, \mathrm{H}_{2}, \mathrm{NH}_{4}\) and water vapor at \(800^{\circ} \mathrm{C}\)
2 \(\mathrm{CH}_{4}, \mathrm{H}_{2}, \mathrm{NH}_{3}\) and water vapor at \(600^{\circ} \mathrm{C}\)
3 \(\mathrm{CH}_{3}, \mathrm{H}_{2}, \mathrm{NH}_{3}\) and water vapor at \(600^{\circ} \mathrm{C}\)
4 \(\mathrm{CH}_{4}, \mathrm{H}_{2}, \mathrm{NH}_{3}\) and water vapor at \(800^{\circ} \mathrm{C}\)
Explanation:
S.L. Miller, an American scientist provided an experimental evidence for chemical evolution in 1953. \(\mathrm{He}\) created an electric charge in a closed flask containing methane \(\left(\mathrm{CH}_{4}\right)\), Hydrogen \(\left(\mathrm{H}_{2}\right)\), Ammonia \(\left(\mathrm{NH}_{3}\right)\) and water vapour at \(800^{\circ} \mathrm{C}\).

Alexander Von Humboldt described for the first time
1 Ecological Biodiversity
2 Laws of limiting factor
3 Species area relationships
4 Population Growth equation
Explanation:
Alexander Von Humboldt a German Naturalist, first described species area relationships - It states that the species richness within a region increases with increasing explored area but only up to a limit. The richness can be explained by this logarithmic mathematical equation:- \(\log \mathrm{S}=\log \mathrm{C}+\mathrm{Z} \log \mathrm{A}\). were, \(\quad \mathrm{S}=\) Species richness \(\mathrm{A}=\) Area explored \(\mathrm{C}=\mathrm{Y}-\) intercept \(\mathrm{Z}=\) Slope of line i.e., Regression coefficient.

Weismann cut off tails of mice generation after generation but tails neither disappeared nor shortened showing that
1 Tail is an essential organ
2 Darwinism was wrong
3 Lamarckism was wrong
4 Mutation theory was wrong
Explanation:
'Inheritance of acquired Characters in organism' given by Lamarck in 1809 and this theory is known as Lamarckism theory. It states that 'changes in structure or function of organ acquired during an individual' lifetime in response to changes in the environment are inherited by its offspring. But this theory was rejected by August Weismann (1892).

Which one of the following is not a living fossil-
1 King crab
2 Sphenodon
3 Archaeopteryx
4 Peripatus
Explanation:
A living fossil is an organism which has remained unchanged in structure and function over a long period of time. These organisms provide valuable insights into the past and can help scientists understand the history of life on earth. - Archaeopteryx is an extinct ancient or lizard bird which shows evolutionary connections between reptiles and birds. King Crab (Arthropoda), sphenodon (Reptilia) and Peripatus (an invertebrate) are examples of living fossils.
