In the afternoon [the portion of the graph with the tilted squares], the ozone levels switched from increasing to decreasing which means that 01:} of this section switched from to {ll in the blanks}. 5. At approximately what time did the ozone levels make this switch? 5. In the afternoon [the portion ofthe graph with the tilted squares], ozone levels are concave upfdown [choose one}, which means that 0"{t} is positiveegative {choose one}. How does our understanding of derivatives help us to interpret CFC reduction efforts? Ozone {03) is a colorless odorless gas made of oxygen. Ozone is ready to react with whatever it meets. This makes it useful for cleaning and disinfecting. However, when ozone encounters living tissues, like our lungs, ozone attacks and damages the cells lining those ainlvays. This causes swelling and inflammation. Some have compared ozone's effect to a sunburn inside your lungs.1 Ozone LEWIS m Phoen'l' Anion\" December 11, 2021 On a clear day, ozone levels can continue to rise all day, and then decrease rapidly after sunset. Since heat, sunlight, and the ingredient gasses each usually increase during the clay, ozone formation also increases. When the sun goes down, there is no energy for ozone formation and fewer ingredient gases, so ozone levels drop. Ill] gas E I5 M Q p. O 1.
