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:
Asexual reproduction is a type of reproduction that doesn’t involve gametes fusing or the change in the number of chromosomes. A spider plant is the perfect example of asexual reproduction, but when it comes to plants like that, it’s referred to a type of asexual reproduction called vegetative propagation.
Answer:
A. Average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.
Explanation:
The graph in the attachment section portrays the average height of plants (cm) on the y-axis plotted against the concentration of sodium phoshate (mg/L) on the x-axis. Based on the observation of the result in the graph, an increase in the concentration of phosphate caused an increase in the average plant height (as depicted by the upward-sloping line).
However, the plant's average height didn't go beyond 35cm despite an increase in concentration of phosphate. This is because the plants has reached a maximum possible height i.e. a height climax. Hence, they cannot grow taller than 35cm no matter the amount of external nutrients (sodium phosphate) supplied.
Therefore, the noticeable trend that can be used to make a conclusion is that average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.
False, because nucleotides are what make up a persons DNA so each person has its own unique order.
