The activities that take place to meet human needs can often be harmful to ecosystems. by developing sustainable practices, however, we can protect our environment. which of the following changes would be most in reaching sustainability? a) building more water treatment facilities b) releasing aquaculture-raised fish into the natural environment c) mining the seafloor to remove valuable energy resources d) using natural gas for fuel instead of burning petroleum

The answer is DEFINITELY NOT building more water treatment facilities or using natural gas for fuel instead of burning petroleum. I would know because i took the test and these are not correct.

Explanation:

not sure if this what   you'r looking for would be percent composition

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
