In Asia due to the presence of number of industries, large number of vehicles produce harmful gases and deteriorates the air quality at large extent. Deforestation and logging of trees are also one of the cause of lowest air quality.
Explanation:
Asia is a developing countries comprises of India, Sri lanka in its south, China, Japan, Korea in its east and south-east direction. There are all total 48 countries. All these countries population density is high. Among them China has world's highest population followed by India.
Over population and excess population density covers the land and deforested land for establishing settlement. Multi storied buildings are using air conditions, refrigerators which emits CFC in environment. Vehicles emit SO2, CO, CO2 etc. These are the facts which lower air quality in Asia.
Protozoan infections are most prevalent in <u>Asia, Africa</u><u> </u>and <u>South America</u>.
Explanation:
Infections caused by protozoans in humans include severe diseases like African sleeping sickness, malaria, amoebic dysentery, giardiasis etc.
These infections are transmitted through arthropod vectors mostly through their bite. Protozoan parasitic infections are common in tropical developing countries than in the developed nations.
When travelers from non-prevalent countries like the United States travel to countries which are prone to protozoan infections, they also become susceptible and get infected when their own immune system is weakened. They become potential carriers when they travel back to their country.
(I would include the map on the attachment)
I believe the answer is Valley and Ridge.
The map that depicted in the picture is the map of Georgia. Number 4 represent the Upper coastal plain of Georgia which consisted of valley and ridge that would be perfect for cattle farm (even though it might not be useful for agricultural purposes)
