Answer:
homeostasis
Explanation:
The homeostasis definition refers to the mechanism used by the body to maintain the body/cell dynamic equilibrium.
"Body/cell dynamic equilibrium" means that the body/cell is not in a complete equilibrium with the enviroment. Instead of this, the body/cell maintain the same enviroment (including electrolites and water levels, blood pressure, temperature, etc) even with the chages on the enviroment.
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:
D
Explanation:
Absolute age is defined as the numeric age of fossils.
To identify the absolute age of a fossil, the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.
Hence, the correct answer is "D".
