3which waters contain the most nutrients and plankton for fish to feed on? the open ocean deep-sea trenches warm-water currents areas of upwelling 4 most ocean pollution is related to? the greenhouse effect use of aquaculture decaying fish human activity 5 what are sediments containing pieces of diatoms used for? making solar cells making glass abrasives and polishes thickening ice cream

3. Area of upwelling

Explanation: Wind blowing across the ocean surface push water away. So, water rises up from beneath the surface to replace the water which was pushed away. This process is called "upwelling". Waters that rises to the surface as a result of upwelling is typically colder and very rich in nutrients. These nutrients "fertilize" surface waters and so, these waters often have high biological productivity for fish to feed on.

Answer 4: Human activity

Explanation: The largest source of ocean pollution comes directly from land sources, such as oil, land, septic tanks, farms, ranches, motor vehicles, among others. Thousands of tons of waste and garbage are dumped into our oceans every day.

Answer 5: abrasives and polishes

Explanation: diatomaceous earth  (Diatomaceous earth is the fossil remains of diatoms)  has  applications, among which can find: mild abrasive in hygiene products such as toothpaste or facial scrubs, liquid absorbent, porous support for chemical catalysts, anti-caking agent, dynamite stabilizer, thermal insulator.

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

yes its like the dead sea which is full of salt which makes you stay afloat

so yes an egg will float in salt
