Explain why acid rain, smog, ocean acidification, and global warming are indirect results of air pollution.

In all of the mentioned cases, the influence of air pollution is not directly associated with the toxicity of the gases. The ocean acidification and acid rain take place when the pollutant gases in the environment react to produce acid. Smog influences the environment by filtering out sunlight and leaving less for the plants to utilize. Global warming takes place as greenhouse gases make Earth hold more of the heat, which it had captivated from the Sun.

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.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
