Maximum Sustainable Yield: The maximum level of water extraction that won’t run out for a given area. Water Conflict. Causes:
National – within the country (between region and states) E.g. Mississippi Israel/Palestine = Access to groundwater aquifer (regional conflict) International – country to country (across borders) Conflicts at the local/national scale Case Study: Managing water demand issues in the Murray-Darling Basin in Australia. The Murray-Darling Basin is a large drainage basin in

Gene Expression
the process by which DNA directs the synthesis of proteins
What situation did Archibald Garrod suggest caused inborn errors of metabolism?
Genes dictate phenotypes through enzymes that catalyze specific chemical reactions in the cell
Describe one example Garrod used to illustrate his hypothesis
Alkaptonuria: urine is black because it contains the chemical alkapton, which darkens upon exposure to air
State the hypothesis formulated by George Beadle while studying eye color mutations in

The role of wetlands as a water resource: A wetland is an area of land with soil that are permanently flooded. It includes freshwater marshes (e.g. Macquarie Marshes in Australia), bogs (e.g. Strangmoor Bog in USA) and swamps (e.g. The Everglades in Florida USA) Wetlands are very important water resource as they provide many ecosystem services. There are marine coastal, inland and artificial types, subdivided into 30 categories of nature wetland and 9 human-made ones such as reservoirs, barrages

Geology
-Layering determined by the differences in both chemical composition and physical properties
-On basis of chemical composition: earth has three layers:
core (dense inner sphere)
Radius 3500 km, 95% iron+ 5% nickel
Inner core (solid) we know it’s solid because both p-waves and s-waves pass through it
Outer core (liquid) we know it’s liquid because p-waves pass through it but s-waves cannot
Mantle (less dense) 2900 km made of rock-peridotite
Lower mantle 2400 km (solid)(bottom)
Asthenosphere 400 km (weak/
