Answer:
The correct answer to the question: What did the Clean Air Act allow citizens to do that no previous U.S. environmental law had allowed, would be: it was the first law that considered citizen lawsuits against the correct enforcement of the statutes stated in the Act.
Explanation:
The Clean Air Act, which was passed originally in 1963, and which has been amended since, with its last update being in the 1990´s, became the first time that the U.S government not only established federal funding for environmental issues, but also regulated environmental topics through EPA (Environmental Protection Agency, 1970) and considered the power that citizens could have to ensure the enforcement of the statutes and provisions considered in the Act. This consideration of citizen suits, is the most important and relevant difference with earlier environmental laws.
Answer:
Option C, Intrapleural pressure is less than intrapulmonary pressure
Explanation:
During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.
This difference in pressure (i.e higher pressure with in the lungs than the atmosphere) causes lungs to remain attached to the chest wall and hence looks inflated.
Hence, option C is correct

Answer:
G=21 %
T= 29 %
A= 29 %
Explanation:
Since C only binds to G, you have the same amount of C and G, so G is 21 %.
100 % minus 42 % ( 21 % C plus 21 % G=) equals 58 %.
So the other 58 % is made of T and A. Since T only binds to A , the half of the extra 58 % is T and the other half is A. Therefore 29 % is T and 29 % is A
