De Vries gave his mutation theory on organic evolution while working on -
1 Oenothera lamarckiana
2 Drosophila melanogaster
3 Pisum sativum
4 Althea rosea
Explanation:
De Vries gave his mutation theory on organic evolution while working on Oenothera lamarckiana (evening primrose). According to De Vries, new species are not formed by continues variation but by sudden appearance of variation which he named as mutations. - Hugo de Vries started that mutations are heritable and persist in successive generation.

Which one of the following phenomena supports Darwin's concept of natural selection in organic evolution
1 production of 'Dolly', the sheep by cloning
2 Development of organs from 'stem' cells for organ transplantation
3 Development of transgenic animals
4 Prevalence of pesticide resistant insects
Explanation:
According to Darwin's theory of natural selection, the individual possessing useful variations survive where as the other are eliminated. - Prevalence of pesticide resistant insects supports natural selection theory e.g. DDT was thought to be an effective insecticide against household pest (like mosquitoes, housefly, body lice) in 1945 . - Pesticide resistant insects are selected over pesticide sensitive insects by nature and are thus survive through the course of evolution, until more suited (fittest) individual is selected, eliminated the former.

Radioactive C-dating and living fossils are used for-
1 Biological age
2 Geological age
3 Age of rock
4 Geographical distribution
Explanation:
A Radioactive C-dating is used for biological age, geological age of rocks. But together with living fossils it is only used for biological age. Radio carbon dating, or carbon-14 dating, is a scientific method that can accurately determine the age of organic material.

Select the option having correct sequence of geological periods - Permian, Triassic, Jurassic
1 \(1 \rightarrow 2 \rightarrow 3\)
2 \(3 \rightarrow 2 \rightarrow 1\)
3 \(2 \rightarrow 3 \rightarrow 1\)
4 \(3 \rightarrow 1 \rightarrow 2\)
Explanation:
The geological time scale is the 'calendar' for events in earth's history. It subdivides all time into named units of abstract time called in descending order of duration - Eons, Eras, Periods, Epochs, and Ages. - The correct chronological sequence of periods of Mesozoic era is Carboniferous \(\rightarrow\) Permian \(\rightarrow\) Triassic \(\rightarrow\) Jurassic Cretaceous.
