Zebra mussels were introduced into the great lakes region in the 1960s. they are not a native species and they spread quickly throughout the area. zebra mussels attach to other species of mussels and often kill them. they also use up resources that native mussel species depend on for survival. as a result, zebra mussels have almost completely gotten rid of native mussels in the great lakes region.

based on the table below, what type of interaction do the zebra mussels have with the native mussels?
organismal function a bodily function, such as heart rate or body temperature, that affects an individual organism
population interaction an interaction between members of the same species, such as mating
community interaction an interaction between members of different species, such as predator/prey interactions or competition between two or more different species
ecosystem interaction an interaction between the biotic and abiotic factors of an ecosystem, such as a drought killing many different plant and animal species in an area

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
