Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.
What are the effects of irrigation agriculture on river basins?Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.
Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.
One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.

Where does carbon dioxide move from the circulatory system to the respiratory system? A. In the vena cava B. In the alveoli C. In the liver O D. In the pulmonary artery
In the alveoli, carbon dioxide move from the circulatory system to the respiratory system.
Where does carbon dioxide move from the circulatory system to the respiratory system?The circulation receives oxygen from the lungs during gas exchange. The blood and lungs exchange carbon dioxide at the same time. This occurs in the lungs between the capillaries, which are a network of microscopic blood arteries found in the walls of the alveoli, and the alveoli themselves.The body's cells are supplied with oxygen and nutrients through the heart, blood, and blood vessels. Blood transports carbon dioxide to the lungs (for exhale) and picks up oxygen through the network of arteries, veins, and capillaries.While carbon dioxide flows from the blood in the capillaries to the air in the alveoli, inhaled oxygen moves from the alveoli to the blood in the capillaries.learn more about alveoli here: https://brainly.com/question/4539268

What are the chemical and word equations for photosynthesis and cellular respiration?
Explanation:
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.
4. While blood contains glucose, potassium, albumin, and chloride molecules, a normal urine sample contains
only potassium and chloride molecules. Why do you thing this is so? (1 mark)
Glucose and albumin (a protein) are too big to pass through the glomerulus therefore they should not be found in normal urine while potassium and chloride molecules are small enough to be filtered through the glomerulus, where it can either be reabsorbed back into the blood or go through the entire tract and be excreted with urine.

The graph below shows how the number of stream pollution incidents changed before and after the pamphlets were mailed. What is one conclusion you can make based on the information in the graph?\
Answer:
Option C. is correct.
I know this because the amount of pollution incidents is represented by higher numbers, so if it went down so dramatically, that must mean the pamphlets caused less people to dump pollution into the water.
