<span>The least likely situation out of those listed here for a scientist to revise her experimental methods, would be if her results support her hypothesis. In this instance, the outcome of the experiment positively provides evidence that the original hypothesis is correct, and the experiment would therefore be a success and not necessarily require repeating.</span>
Answer:
Hypothesis: If there is a rat, THEN an elephant will react differently
Independent variable: Presence or absence of rat
Dependent variable: Elephant's reaction
Conclusion: The hypothesis is accepted because rats make an elephant to react.
Explanation:
A hypothesis is a predictive statement about a particular observation made, which is what we're doing next. In this case, a possible statement that suggests solution could be: If there is a rat, THEN an elephant will react differently.
Independent variable is the variable being manipulated in an experiment. The PRESENCE OR ABSENCE OF RATS is the independent variable
Dependent variable is the variable that the experimenter measures. In this experiment, the measurable variable/dependent is the ELEPHANT'S REACTION.
Conclusion of an experiment either rejects or accepts the hypothesis depending on the outcome of the experiment. In this, let it be assumed that the conclusion has been accepted
Answer:
A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.[1] The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants,[2][3] adapted to the unique hydric soil
Answer;
-These are positive impacts of dams to the society.
Explanation;
-Dams are important because they provide water for domestic, industry and irrigation purposes. Dams often also provide hydroelectric power production and river navigation.
-Other positive impacts include; dam wall itself blocks fish migrations, which in some cases and with some species completely separate spawning habitats from rearing habitats. It also traps sediments, which are critical for maintaining physical processes and habitats downstream of the dam.
