Most animals have an excretory system that either eliminates ammonia quickly or converts it into a less toxic substance that is removed from the body. Excretory systems vary from groups of cells that pump water out of the body to complex organs such as kidneys. Response: Animals respond to events in their environment using specialized cells called nerve cells. In most animals‚ nerve cells hook up together to form a nervous system. Some

These tests helps us to determine the properties of the drilling fluid and so what can be done to make the mud perform more efficiently. For the density and rheological properties a mud balance is used to test density i.e. fill the cup so that a little is ejected through the hole at the top and then move the weights until balance is achieved which is indicated by the bubble in the spirit level

deep-set hand pump tubewells inoperable. This project work deals with the design of deep tubewell with reasonable specific drawdown to overcome hazardous situation for more groundwater for irrigation in the dry season. The important aspects of the work is to describe the formation samples and designing the tube well in order to minimize the amount of head loss due to movement of water through the aquifer. The lower the head loss‚ the smaller the drawdowns‚ less fuel have to be used to pump the water
