List the offspring's genotypes and phenotypes. b. Explain what a mutation is and how it occurs. c. Discuss two types of mutations.

Emily Bernardi Hereditary Variations and Genetic Disorders

a. State and explain at least three forms of hereditary variations. b. Explain how these types of variations can lead to certain genetic disorders. c. Chose one genetic disorder and explain how it is caused, and what systems in humans that it affects.

Brian Millham Big Idea 3 and Big Idea 4

Describe 2 specific types of diffusion across a cell membrane. c.) Explain how one of these types of diffusion contributes to overall metabolic processes of an organism.

Kenna Garrison Big Ideas 2 and 4

a. Describe the two types of population growth. b. Discuss the types of factors that lead to population growth leveling off. c. Explain how the introduction of a non native species could affect an ecosystem. Give a real world example.

Kayla Kaufmann Big Idea 2 (Regulatory Systems) and Big Idea 3 (Genetic Disoders)

A. Why do organisms use feedback mechanisms? Identify the two types of feedback. B. How are the different types of feedback different from eachother? C. Discuss the genetic disorder, type I diabetes, and how it causes a disruption to a feedback loop. Name which type of feedback it disrupts.

Jake Barry Big Ideas 2 and 4 a. Define and describe how Competition, Parasitism, Predation, mutualism, and commensalism. b. Describe 2 real symbiotic relationships. c. Regarding one of your answers to question b. why was this relationship chosen for evolutionarily?

Amanda Vespermann Big Ideas 1 and 4 A population is initially in Hardy-Weinberg equilibrium. 32% of organisms display the recessive phenotype. a. Explain four conditions required for Hardy-Weinberg equilibrium to take place. b. Determine the values for "p" and "q" in this population. c. Predict how a change in the temperature of the environment would affect this population, assuming the recessive genotype is advantageous. Would this affect the population, community, energy flow in the ecosystem?
