Sedimentation accumulation found in bodies of water can be the result of a. fertilizer runoff b. pesticides and herbicides c. erosion from agricultural practices d. all of the above select the best answer from the choices provided a b c d

C

Explanation:

Sedimentation is simply the deposit of materials such as gravels, sands, clay, silts e.t.c. All of these materials can be from different sources.

When erosion occurs materials can be carried as dissolved load in solution, suspended load and bed load.

Fertilizers applied in a farm can be carried in a run off which can be sedimented in a body of water. Pesticide and herbicides can also suffer the same fate.

Agricultural practices can loosen the soil and cause massive erosion. These materials will finally find a way to be deposited in a basin.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
