Hint: Charles Darwin is famous for his theory of evolution called Darwinism. His theory says that species change over time gives rise to new species. The new species are selected by natural selection. His theory is widely accepted.
Complete answer:
To solve this question, we must know about the theory of evolution by Darwin.
Charles Darwin was an English biologist who is widely known for his contribution by proposing the theory of evolution by natural selection. He stated that the species change over time and give rise to new species which share a common ancestry.
These changes are inheritable. The changes can be physical or behavioural. These changes help the organism to adapt to the environment. This helps the organism survive and produce more offspring.
The theory is also referred to as the survival of the fittest. Natural selection can change a species in many ways. These changes are called microevolution. It causes change in color or size which is inherited over generations.
Isotonic molecules- The solution in which the concentration of solute and solvent are the same is called isotonic solution. In an isotonic solution, there is no net flow of molecules.
Hence, the correct answer is option (B)
Note: Natural selection is a natural process which happens in nature due to which the organisms better adapt with the environment. These adaptations help the organisms to survive, reproduce and produce offsprings.
