The sewing needle should float in the water if placed on a horizontal angle if I remember properly.

High rates of
volcanism, earthquakes, and mountain building are the sites of subduction
zones. They occur in convergent boundaries found in tectonic plates of both
oceanic and continental crusts. Subduction zones occur when one tectonic plate
moves under another tectonic plate, sinking into the mantle as the plates
converge again.

Regions that are
within subduction zones experience an average rate of convergence of 2-8
centimeters per year. They are subject to many earthquakes because of the
collisions that occur within the tectonic plates. </span>
First of all, it makes algae grow, because pesticides and stuff provide too many nutrients. Algae needs a lot of oxygen and so the fish begin to die off because the algae is taking all the oxygen out of the lake. Next, it causes biodiversity to drop, meaning that species are beginning to get less varied. Water pollution harms the lakes and is a concern because the effects of it on species and the water will stay.
Answer:
They are used to transport electron during metabolic reaction.
