Question:
Species occupying different geographical areas are termed as
Species occupying different geographical areas are termed as
Updated On: Aug 13, 2024
- sympatric species
- sibling species
- allopatric species
- endangered species
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Allopatric species are related to groups of similar organisms that could interbreed but do not because they are geographically separated. Sympatric species are in close proximity and theoretically capable of interbreeding, but do not interbreed because of differences in behaviour. Sibling species are diode that have both parents in common. Endangered species are those defined by IUCN as being in immediate danger of extinction because its population numbers have reached a critical level or its habitats have been drastically reduced.

- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
