The correct answer in your case would be B - sensing changes in the external environment. Our sensory apparatus ( our eyes, nose, taste, hearing) all help and contribute towards the detection of changes that could be found in the external environment. All of these changes get transmitted and processed in the brain and nervous system in general.
The alternation of generations is an important concept in the evolution of plants. All land plants have alternation of generations. In mosses and their relatives (Bryophytes), the haploid gametophyte is the dominant generation, and the diploid sporophytes are sporangium-bearing stalks growing from the gametophytes.

Canada is bigger than the United States, but only has approximately one ninth (4) of the population. Canada has a population of approximately 35 million and the United States has a population of around 315 million people.
The rate of osmosis increases with increasing differences in solute concentrations between two solutions separated by a selectively permeable membrane.
Osmosis is the movement of solvent from an area which is having a low concentration of solute to an area having a high concentration of solute through a semi-permeable membrane. It is a type of diffusion and does not require any energy to occur. Osmosis helps cells to maintain their osmotic pressure and maintain the cell shape.
So if the difference in solute concentration between two solutions which are separated by semi-permeable membrane increases than the rate of osmosis will increase to maintain the balance of solute concentration of both the site.
