It takes seven seconds for the pupil to adapt once again to dark conditions after getting exposed to headlight glare.
The pupil of the eye refers to the black circle at the midpoint of the iris. The pupil functions mainly to monitor the amount of light getting inside the eyes, to make sure that to much light does not blanch out the visions in extremely bright light conditions, and to capture as much light as possible in dim light conditions.

Darwin proposed an idea that all species change over time because those that are best adapted to their environments are able to survive and pass on their traits to their offspring. This became known as Darwin's theory of evolution. This historic insight was described based on his observations of the inhabitants of the Galapagos Islands.
The correct answer is (A.) bacteriophages using DNA to infect bacteria.
Explanation
1. In 1952, Alfred Hershey and Martha Chase did experiment to find the genetic material in organisms.
2.Bacteriophages (viruses that affect bacteria) were the key element for Hershey and Chase experiment.
3.In which they concluded DNA as genetic material as bacteriophages use DNA to infect bacteria and not protein.
Answer:
C. There are more solvent molecules than solute molecules in the solution.
Explanation:
An equilibrium exist when there is equal distribution of solute and solvent present in a solution otherwise it will be not.
The undistributed solvent and solute concentration undergoes the process of osmosis through which solvent molecules moves from lower to higher concentration through a semipermeable membrane and redistribute the concentration.
The redistribution of molecules reaches the equilibrium, so, until there is more solvent molecules than solute molecules in the solution, there will be no equilibrium.
Hence, the correct option is C.
