Answer:
The correct answer is - a toxic spill that affects a drinking water supply.
Explanation:
The Clean Water Act (CWA) establishes the basic structure for regulating discharges of pollutants into the waters of the United States and regulating quality standards for surface waters. Under the CWA, EPA has implemented pollution control programs such as setting wastewater standards for industry.

Answer:
If a father has a blood type AB and his wife has a blood type O, their children could be a blood type A or B, with a 50/50 chance.
Explanation:
Blood type and heredity are determined by surface antigens on the red blood cell, called A and B. The surface antigens provided by each parent are genetically encoded:
- <em>Blood type A </em><em>corresponds to the presence of antigen A, and its genotypic expression can be A/A or A/O.
</em>
- <em>Blood type B</em><em>, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen.
</em>
- <em>AB blood</em><em> —due to co-dominance— has a gene for A and another for B, with genotype A/B.
</em>
- <em>Blood type O</em><em>, characterized by the absence of surface antigens, behaves as a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.
</em>
In the case posed the father has the blood type AB and the mother the blood type O, so:
- ♂ blood type AB, alleles A|B
- ♀ blood type O, alleles O|O
The crossing can be seen graphically in the diagram:
Alleles A B
O A|O B|O
O A|O B|O
According to this, the offspring of this man and his wife could be:
- Children with blood type A, genotype A|O, 50%
- Children with blood type B, genotype B|O, 50%
Ovum cell, ciliated epithelial cell, and nerve cells
