Answer:
- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.
- The solutions are hypotonic to the solution in the potato cells.
Explanation:
According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.
Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.
Answer: Increase in species numbers and diversity
Explanation:
Upwelling is an oceanographic phenomena in which the water from the bottom layers of the ocean usually above the seafloor get displaced and reach upto the surface layers with the effect of wind currents. The water carries away along with it the nutrients and the organic matter to the surface layers which allows the efficient growth of plant and planktonic diversity which favors the growth of sea animals like fishes and others. Hence, by this way the species diversity and numbers increases by the process of upwelling.
Answer:
Some people offer more prejudice on the sexual orientation because sexual orientation like gay marriages were not seen in the world before. Before the 21st century, the same- sex marriage was never seen or heard about. So, today people display more prejudice regarding this issue because sexual orientation began in the 21st century. Many people are of the view that this same sex marriage is not traditional and hence it is not right morally. While others believe that every person has the right of freedom and this is their civil right to do what they like.
The discrimination based on race and gender has been an issue from the start of human lives. Almost every country has a history which shows race and gender discrimination. Hence, though majority of the people today are against this but still is is not as a hot and new topic for prejudice as the topic of sexual orientation is.
