Stonefly larvae, for example, are very sensitive to polluted water and low dissolved oxygen. You collect a lot of stonefly larvae in your study of a local stream and conclude that this stream has high levels of dissolved oxygen and is minimally polluted. Your conclusion is an example of deductive reasoning.
- In both science and daily life, deductive reasoning is a sort of deduction. It occurs when you combine two genuine premises to arrive at a conclusion.
- As an illustration, A = B. B and C are also equal. Deductive reasoning allows you to draw the conclusion that A and C are equal given those two statements.
- Every dolphin is a mammal, Every mammal possesses kidneys.
- You can draw the conclusion that all dolphins have kidneys through deductive reasoning. Keep in mind that for this to function, both assertions must be true.

Answer:
You can react it with water to produce energy-rich hydrogen gas, or with hydrogen to produce useful chemicals, such as hydrocarbons or alcohols. If there were a sustainable, cost-efficient route to transform CO2 to CO, it would benefit society greatly.
Explanation:
Answer: Water Volume: The volume of water(discharge) in a stream affects the energy(velocity) of that stream. As the volume of the water in the stream increases, the velocity increases. ... Incline gradient: The incline gradient is also known as the slope of the stream.
Explanation:
Answer:
The correct option is <em>Genetic drift greatly affects small populations, but large populations can recover.</em>
Explanation:
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are <u>harder in a small-sized population.</u>
Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to randomly attach one of the alleles.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
In the exposed example, the hurricane caused a disaster in both populations, reducing the number of individuals on the island and in the mainland. Henry saw a decrease in genetic variation in the island species, but not in the mainland species. This could be because the island population was smaller than the mainland population, so it was more affected by the disaster. The loss of some alleles in the population caused a decrease in genetic variation in the island population.
