1) List 2 adaptations of plants in the grassland and 2 of those in the desert.
2) Define ecosystem service, and provide an example.
3) Describe the role of fire in the Savanna.

1. Grassland: deep root systems and flexible stalks. Desert: waxy coatings and photosynthetic stem.
2. The free benefits humans get from an ecosystem. An example is a clean source of water.
3. Fire helps to maintain the open vegetation structure

Given a species is in Hardy-Weinberg equilibrium and has two alleles, H and W, where the frequency of H is 32%, what proportion of the population is heterozygous HW?

2*0.32*0.68 = 0.4352, so rounding to 2 significant figures, 44% of the population is heterozygous HW.
