Answer:
Testing only one Variable at a time lets you analyze the results of your experiment to see how much a single change affected the result. If you're testing two Variables at a time you won't be able to tell which Variable was responsible for the result.
Explanation:
Answer:
1. True
Biotic factors can have effect on abiotic factors like water by the way they use it and how much they drink. If biotic factors drink too much water in a rivver then it could end up with limited amount of water for the ecosystem.
2. False
On average, about 50 percent of energy available within one trophic level is transferred to the next trophic level.
3. True
Extirpation is extinction of a species in a given area.
Answer:
Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.
The correct answer should be A. What measurements will be used to evaluate me?
This can help you understand what standards will be applied when measuring your performance.
