One of the ways we make sure data is reliable is by repeating and replicating experiments.
If we consistently get the same results, then this means that the data is both credible and reliable.
Hopefully, this helps! =)
Pond ecosystem considered as an open ecosystem because pond is always open . There is an interaction of pond with atmosphere , due to which it ecosystem becomes open.
Typically, higher order streams contain MORE water than lower order streams.
Stream ordering is a mean of classifying natural channels in a water shed based on their sizes. The first order stream is the smallest stream and the second order stream is bigger than the first. Thus, the amount of water in the first order stream will be less that that of second order.<span />
Adaptations shouldn’t end up causing difficulties for the animal so that eliminates options A and D. Option B can be eliminated because a long beak more than likely wouldn’t help a bird hide from predators, if anything it could make it stand out more. So, the answer is C
Pollution, over population, anything that could be potentially harming the earth in the long term.
