Atmospheric pollutants can lead to a variety of environmental problems. Scientists have identified specific chemicals, including carbon dioxide (CO2), sulfur dioxide (SO2),
and chlorofluorocarbons (CFCs) which many hypothesize cause specific environmental
responses. Identify ways humans are involved in adding these chemicals to the
atmosphere and describe the specific effects scientists hypothesize each of these
three chemicals has on the atmosphere.

where is the scientific experiment?

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
