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:
The correct answer is both pumps use proteins to transport substances across the cell membrane.
Explanation:
Sodium potassium pump helps in the active transport or uphill transport of both sodium and potassium across the cell membrane against their concentration gradient.
Whereas Ca2+ATPase or calcium pump itself is a trans membrane or membrane spanning protein which helps in the transport of Ca2+ outside the cell to maintain electrochemical potential of Ca2+ ions.
Prey-predator relationship. Explanation: The relationship between the praying mantis feeding on a bee.
PROTANOPE. These are the individuals that suffers form color blindness. This color blindness is due to the absence fo the L- cones which are cones that are sensitive to long wavelength. Cones are one of the three types of photoreceptos found in the retina. These are responsilble for color vision and function best in a brightl light. In contrast to the rods which works on dim light. Cones are found in the fovea.
