What data could most likely be accurately replicated by other scientists?
lions [1.4K]
I don't think it's A. Think of all the different colors, ages, and unique predetermined ( by environment and genes) physical abilities of mice. Not to mention the fur, which would hinder any observations made off of the animals' skin (physical appearance). There would be plenty of data, but it would be inaccurate data. Just like measuring a horse in hands (when all hands are different sizes), or like determining the distance between trees in steps ( when everyone has varying lengths of stride). C is the correct answer, as it is the only data which can be replicated. ( If one scientist measures in millimeters, then another scientist will be able to get the same results.)

Respiration needs light to occur just as photosynthesis needs light true or false​
Triss [41]
False, respiration can happen in the dark. Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.

Which of the following would not be considered a point source pollution contributor? a. an animal feedlot b. cattle on rangeland
Luden [163]
The correct answer is b: cattle on rangeland. A point source of pollution occurs from a single identifiable and usually spatially narrow source. These sources of pollution are usually relatively easily to quantify and manage. In contrast, a non-point source of pollution, such as cattle on rangeland or irrigated agriculture, is variable on both spatial and temporal scales. These sources of pollution are difficult to quantify and manage.
