Answer:

Low levels of fecal coliform

Explanation:

The pH (hydrogen potential) of a water considered <u>pure</u> is 7. Since the ideal pH for consumption is between 6.5 and 8.5 (neither too alkaline nor too acidic), so the first statement is false.

A low level of fecal coliforms indicates lower risk of contamination by various types of microorganism, allowing water to be consumed. So the second statement is true.

3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)

4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would

5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.

What biodiversity restoration method can biologists follow to increase the density of trees and the canopy thickness in an area
alekssr [168]
Reforestation is a biodiversity method that can increase the biodiversity by replanting with trees. Reforestation will help forest recuperate from logging, rest fires and human abuse. Replanting trees will increase the density and variety of the trees and by doing so, wildlife will also increase. Although reforestation is a common approach to relive forest, forest management is still needed to maintain the endemic or native species.
