Answer:

              1. When a rubbed ruler is brought close to the paper, salt and pepper they are not equally attracted as paper is lighter than pepper and salt, so it takes less effort for paper to overcome the force of gravity.

2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged.  Electrostatic interaction also depends upon the nature and mass of body.  

b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.

High-latitude ocean water tends to support large planktonic communities because ________. of higher dissolved carbon dioxide the
aleksklad [387]

Answer: They tend to support large planktonic

communities because (of higher dissolved oxygen and nutrient concentrations).

Explanation:

Planktonic communities are made up of basic organisms that forms the oceanic food web. They are broadly divided into Phytoplankton (these are the producers), Zooplankton (these are the consumers) and Bacterioplankton (these are the recyclers).

High-latitude ocean water is mostly affected by the quantity of oxygen and nutrients it contains. Large planktonic communities thrives in these aquatic environment because is contains higher amount of dissolved oxygen and nutrient concentrations which forms part of their basic needs for survival. This is so because changes in ocean water can impact all levels of the food web. Increase or decrease in ocean temperature can modify the plankton diversity and distribution directly by altering it's metabolic rates and growth.

Therefore due to the geographic location of high latitude ocean, higher dissolved oxygen and nutrient concentrations favour the survival of a larger planktonic communities than other ocean parts.
