Which type of pollution includes CFCs and smog? Air, land, water or volcanic

Answers

Answer: Air pollution.


Air pollution occurs when harmful substances are introduced into the atmosphere. These substances majorly exist in two forms i.e solid ( particulate matter in air) and gaseous form.


CFCs (Chlorofluorocarbons) are compound consisting of Chlorine, fluorine, and carbon atoms. They are released in the atmosphere through aerosol sprays, air conditioners, refrigerators etc. Due to longer lifespan in the stratosphere, they can cause damage to the ozone layer thereby reducing earth's protection from harmful UV radiation. Also, they have warming effects which may cause global warming.



Smog is primarily named for the mixture of smoke and fog in the air. It is a blackish fog formed in the atmosphere mainly due to the reaction of various gases with dust and water vapors. it causes breathing difficulty and other harmful consequences.

Describe how the organisms in your cladogram are related through common ancestors.

Answers

A cladogram shows how species are related by descent from a common ancestor. A classification of organisms on the basis of such relationships is called a phylogenetic classification.

A phylogenetic classification involves organisms in a clade with their common ancestor.

How organisms are related in cladogram?

A cladogram consists of an organism being studied, lines, and nodes where those lines cross. The lines represent evolutionary time or a series of organisms that lead to the population.

A clade is a group of living organisms and the common ancestor they are derived from.

Therefore, the cladogram is related to common ancestors through their species.
