The answer is totally D. Chemical messenger !
none of the others really make sense haha
Gases trap heat and cause the greenhouse effect. Solar radiation warms the earth, while the atmosphere traps it.
Leads to seasonal patterns, when the earth is tilted to the northern hemisphere its summer and when the earth is tiled to the south, its winter.
Results in some of the atmosphere to be warmer than other parts, it changes in volume and pressure which results in strong weather.
As wind or ocean current moves, the Earth spins underneath it.
Melting of the ice mass at the poles, which causes rising sea level, producing flooding and endangering coastal habitats
Shock waves, heat radiation, the formation of craters with associated earthquakes, and tsunamis if water bodies are hit or caused by the earthquakes.
jeopardizing latitude, water elevation, ocean currents, topography, most habitats, and prevailing winds.
The dependant variable would be the salmon, because they depend on the water and pollution levels to give a result.
Answer:
<em>What is the role of alveoli in respiration ⇔ Alveoli are the place where the exchange of gases takes place. The outer part of alveoli has blood vessels. These vessels are carrying Co2 rich blood to exchange at the alveoli. The O2 from the alveoli is diffused into the blood while co2 is sent into the lungs. That O2 rich blood is then carried to heart to pump it to the whole body. and this process continues. </em><em>The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.</em>
