Answer:
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. ... Leaching may also refer to the practice of applying a small amount of excess irrigation where the water has a high salt content to avoid salts from building up in the soil (salinity control).
Explanation:
Answer: Option C.
Explanation:
The bird's lung are said as more efficient than a human or mammals.
The bird's are having small lungs with nine air sacs playing an important role in respiration.The air sacs allows a unidirectional flow of air inside the lungs while in human the air flow takes place in bidirectional. Unidirectional flow results in the flow of fresh air along with high oxygen content in bird's lung. So, there is more oxygen available to diffuse into the blood in bird lungs.
Hence, the correct option is C.
Answer: G C A A T G G C
Explanation: adenine (A), thymine (T), cytosine (C) and guanine (G). Each base can only bond with one other, A with T and C with G.
Short, fast sprint
Explanation:
During the short period of the fast sprint, the muscles are demanded to act really fast and are therefore exerted because there is little time for oxygen to diffuse into the tissue and satisfy the energy needs of the muscles. The energy demand is higher than the oxygen supply. Therefore cellular respiration of the cells of the tissue incline towards anaerobic respiration (glycolysis in the cytoplasm). This fast pace can't be sustained because glycolysis is an inefficient way of generating energy by cells. Pyruvate, the end product is converted into lactic acid. Accumulation of lactic acid causes muscle spasms.
