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.

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

-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/
