Introduction And what is known about the sustainability of current groundwater‚ it is that it will not last. Ponce (2006) states” The unsustainable use of groundwater stands to significantly impact a host of hydrological‚ ecological and other natural resources and services‚ including freshwater bodies‚ and aquatic‚ riparian‚ transitional‚ and ecosystems.” All life on planet earth depends on clean freshwater to survive and It is very important that this natural resource is taken care of properly

increases‚ we observe an increase in the thermal energy of the substance. This change in thermal energy is associated with the change in temperature of the substance‚ however‚ it is important to note that thermal energy and temperature are not the same properties even though they are related. Temperature measures the average thermal energy of the substance and does not depend on the number of particles in the system‚ whereas the total thermal energy does depend on the number of particles.

ANATOMY 2 LAB 1 – RECEPTORS Questions: 1. How is the distance between receptors related to sensitivity of a stimulus? * The greater the distance between receptors and stimulus the lesser sensitive are the stimulus. The smaller area‚ the more sensitive. 2. What does the two-point discrimination test measure? * It measures the smallest distance at which two points of contact can be felt or measures areas that are more sensitive and has more motor interactions. 3. What areas of
