For his class project, mike needs to collect samples of algae. in which section of a river is mike most likely to find algae? a.) middle section of the river b.)source of the river c.) mouth of the river\ d.) all along the river

Option A

Explanation: There will be more deposition found in the middle of the river as it will have more deposition of fertilizers containing nitrogen and phosphorous.

The more will be the deposition, more will be the algal bloom. The sections of the river having running water will have little or no algal bloom as there will be less deposition of the substances favoring algal bloom.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
