Answer:
The population in the study are adults over 18 years.
Explanation:
The population in a research work is the entire group of people with specific characteristics that the researcher wishes to study. The population is usually so large that sometimes, it would be very difficult to study all of it. So, most times, the researcher resorts to taking a sample from the entire population and generalizing the result of the findings.
In the study above, the researcher wishes to measure the depression among adults over 18 years. This is the population, which is so large because there are many adults over 18 years. So, the researcher makes his work easier by taking samples from students in your class.
I assume that the question here refers to the process of evolution. The "helpful variations" are small mutations that allow the organism to have a small advantage over other - and this organism can then pass this variation to its children better than other organisms, meaning that with time, more organisms will have it. This will accumulate over time and the percentage of organisms with this mutation will increase.

Answer:
The concept of sustainable development can be interpreted in many different ways, but at its core is an approach to development that looks to balance different, and often competing, needs against an awareness of the environmental, social and economic limitations we face as a society.
All too often, development is driven by one particular need, without fully considering the wider or future impacts. We are already seeing the damage this kind of approach can cause, from large-scale financial crises caused by irresponsible banking, to changes in global climate resulting from our dependence on fossil fuel-based energy sources. The longer we pursue unsustainable development, the more frequent and severe its consequences are likely to become, which is why we need to take action now.
