Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
The correct answer is D. 59 years and younger.
Explanation
The image shows a pie chart showing the population percentages in Florida in 2013 by age. In this graph there are 5 main groups: Dark blue color that represents the population of 19 years or less, which corresponds to 23.5%; yellow color represents the population from 20 to 39 years old, which corresponds to 25.1%; green color represents the population from 40 to 59 years old, which corresponds to 27.5%; The red color represents the population aged 60 to 79, which corresponds to 18.8%. According to this information, it can be concluded that about 75% of the population is 59 years of age or younger.
This can be verified by adding the percentages of each population 23.5% (19 years or less) plus 25.1% (twenty to thirty-nine years) plus 27.5% (forty to fifty-nine years) add up to 76.1 %.
So the correct answer is D. 59 years and younger.

(Sorry if it's wrong im new)
The answer is; plankton
The major group of plankton that contribute to earth’ crude oil are phytoplanktons because of their great numbers – even though they are microscopic. They are the base of the food chains in the oceans because they are the main primary producers. Examples of phytoplankton are the dinoflagellates, cyanobacteria, diatoms and blue-green algae.
