The electron microscope has a significantly higher resolution compared to the light microscope, allowing researchers to visualize much smaller structures and details within cells. This increased resolution is due to the shorter wavelength of electrons compared to photons (light), which enables the electron microscope to distinguish finer structural features.
So, the correct option is (A): the resolution power of the electron microscope is much higher than that of the light microscope.
Given below are two statements:
Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.
Statement II: RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defence.
In the light of the above statements, choose the most appropriate answer from the options given below:
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.
