Answer: Option C) "excludes agricultural runoff"
Explanation:
The Clean Water Act (CWA) established in 1972 is a federal law made in United States to address the adverse effect of water pollution. The act was aimed to maintain the physical, chemical, and biological integrity of the nation's waters.
A major shortcoming of the Clean Water Act (CWA) is agricultural runoff which is a nonpoint source (NPS) pollution. Large scale agriculture activities have an adverse impact on groundwater and surfacewater as they carry heavy fertilizer, pesticide and water inputs.
The federal CWA establish water quality standards and total maximum daily loads (TMDLs) to asses the pollution caused by agricultural water with the help of regulatory mechanisms.
Hence, the correct option C.
Answer:
- to have cell walls made of chitin
- eukaryotic heterotrophs
Explanation:
Domains are the highest taxonomic category in which living beings can be grouped or divided. There are three domains: archaea, bacteria, and eukarya.
The eukarya domain is composed of the Protist, Fungi, Plantae, and Animalia kingdoms.
Kingdoms include different phyla closely related.
The Fungi kingdom includes yeasts, molds, and mushrooms. All of them are characterized by the same general aspects.
All the members of the kingdom
-
Lack mobility, growing on the ground, organic matter, or other surfaces.
- They all have a rigid cell wall composed of chitin.
- They grow like hyphae, which are cylindrical uniformed structures that might reach many centimeters in length.
- Heterotrophic nutrition. The species can not produce their own food, so they decompose organic matter and get the nutrients from there.
- Reproduction is by spores, which are resistant to adverse environmental conditions.
