Those proven to cause cancer and other major health effects are considered hazardous air pollutants. According to the Clean Air Act, the EPA must regulate harmful air pollutants, or air toxics, coming from specific types of industrial operations in two phases.

Hazardous air pollution stationary source requirements are known as National Emission Standards for Hazardous Air Pollutants (NESHAP). The term "hazardous air pollutants" (HAPs) refers to airborne contaminants that are known or strongly suspected to be responsible for cancer, as well as other major health issues such birth defects or reproductive problems.

The EPA creates national enforcement programs that are centered on serious environmental concerns and patterns of noncompliance.

Snout Shape: Alligators have a wide, rounded, u-shaped snout, while crocodiles have long, pointed, v-shaped snouts. ... Crocodiles are different from alligators in this sense, where both upper and lower jaws of a crocodile are the same size, exposing their teeth as they interlock, creating the look of a toothy grin.

Alligators have U-shaped faces that are wide and short, while crocodiles have thin V-shaped muzzles. When an alligator closes its mouth, you tend to see only its upper teeth. Crocodiles on the other hand flash a toothy grin with their top and bottom teeth interlacing.

Drop in air pressure takes place when one goes up a mountain.

• Altitude is associated with air pressure, that is, with an elevation in altitude, there is a drop in air pressure.

• That is why when one goes up the mountain, the person feels a drop in air pressure.

• The air pressure is indicated with the help of an instrument called altimeter.

• There are two reasons of the drop in air pressure with altitude, that is, gravity and density.

• The high altitude regions like mountains are generally much colder than the regions closer to the sea due to low air pressure.

Thus, the correct answer is option C.

Answer:

The correct answer is ''pharyngeal slits (or clefts) of invertebrate chordates.''

Explanation:

The neural crest is a temporary structure that develops as the neural tube closes. Its migratory capacity and subsequent distribution during development is a basic point in the general embryonic development and of most organs and structures in particular.These cells contribute to the formation of head cartilage and tooth dentin in fish embryos; and a large number of tissues and structures are formed from the migration of neural crest cells. Invertebrate chordates are animals of the Chordata phylum that have a notochord at some point in their development, but do not have a backbone. With a hollow nerve cord, neural tube. It appears by invagination of the dorsal surface; the tube is formed with a central cavity lined by ependyma; the anterior part of the neural tube gives rise to the brain. The neurenteric canal is a communication channel between the neural tube cavity and the intestine. The pharyngeal clefts (pharyngotremia), originally used for food; It is a filtering device that retains food particles that are included in mucus and transported to the intestine. In fish it already acquires respiratory function. In the ventral part, a groove is formed with cilia and bands of glands: endostyle or hypobranchial groove.

African National Congress.

Explanation:

The practice or system of Apartheid was one way the government of South Africa implemented to 'manage' the majority of black people. Though the whites are in minority, they wanted to stay superior. So, the practice of Apartheid gave them the 'scope' for authority, segregating the blacks from them.

The African National Congress, formerly known as the South African Native National Congress, was founded in 1912 by John Langalibalele Dube. The party's aim was to unite all the African people and bring them together as a united nation, irrespective of tribe or background. It later became the main party to oppose the Apartheid policy of the government. After a violent outcome of a peaceful protest, the South African government banned the party in April 1960. This ban was lifted in February 1990.
