Answer and Explanation:
Engine irrigation pumps are used to propel water into the irrigation channels, providing full water supply to agricultural crops. The use of the engine pump has advantages and disadvantages. Among the advantages, we can present the simplicity of operation of these pumps, being easily operated efficiently. They also save energy and are essential for irrigation with more viscous liquids, when necessary. This feature is the main reason for using this type of pump.
Among the disadvantages we can say that these pumps have a slower and less accurate work.
A gas flow from an area of high pressure, to an area of low pressure. The diaphragm expands and contracts to manipulate the pressure within the lungs to either be greater or less than the atmospheric pressure.
Answer:
- Transpiration is loss of water vapor from leaves.
- Guard cells regulate whether stomata are open or closed based on availability of water in the plant.
- When stomata are closed, the plant is not able to exchange oxygen and carbon dioxide gas with the atmosphere
Explanation:
The gas exchange of plants is part of the cellular respiration process, where the plants both remove and release gases into the atmosphere. This exchange happens through structures present in the leaves of plants, which are called stomata. Stomata function as doors, if they are closed it is impossible for the plant to promote gas exchange, but if they are open. Transpiration occurs with the release of water vapor through open stomata. It is in this water vapor that the plant releases oxygen into the atmosphere.
The opening and closing of the stoma is a highly regulated process, because opening the stoma makes the plant lose water. In this case, the guard cells are responsible for opening and closing the stoma whenever necessary and the plant has good water levels.
The muscular system allows for movement within the body, for example, during digestion or urination. Smooth muscles in the gastrointestinal or GI tract control digestion. The GI tract stretches from the mouth to the anus. Food moves through the digestive system with a wave-like motion called peristalsis.
