Frog species in the genus Rana are separated by reproductive barriers. Explain how behavioral isolation maintains species boundaries, and compare it to temporal isolation.

Describe how exon shuffling occurs and analyze its evolutionary significance. How might this process generate novel protein functions across lineages?

Pesticide resistance evolves in insect populations. Explain how natural selection acts on genetic variation to produce resistant populations, and evaluate why this is an example of microevolution.

The oxygen revolution enabled aerobic respiration. Explain how this adaptation transformed energy metabolism and evaluate its role in the rise of complex life.  

According to punctuated equilibrium, species change rapidly and then remain stable. Evaluate how fossil evidence supports or challenges this model compared to gradualism.

Instructions Write three fully developed paragraphs. Grammar, spelling, and punctuation matter. Use in-text or parenthetical citations when drawing from course sources. Introduction and conclusion paragraphs are not necessary. Focus on development of the three main paragraphs. Prompt Throughout Units 1–3 of this course, we have studied how communities of color have been subjected to dehumanization — and how they have simultaneously resisted it. In class, Profe Rivera described four types of narratives: stock stories, concealed stories, resistance stories, and counter stories. Using two specific examples — one drawn from the experiences of Native American communities (Unit 2) and one drawn from the experiences of African American communities (Unit 3) — analyze how these narrative types function. What stock story has been told about each community? What concealed or resistance story challenges that narrative? What does each community’s act of resistance reveal about their agency, identity, and vision of justice? How do these examples connect to what Margaret L Andersen & Patricia Hill Collins call the matrix of domination?

Instructions For each keyword, write 5–7 sentences that include all three components: Define the keyword in your own words. Textual Context — cite a specific reading, lecture, film, or class discussion that addressed this concept (e.g., “As Crow Dog describes in Lakota Woman…” or “In the film 13th…”). Significance — explain why this concept matters: what does it reveal about power, race, identity, or resistance in the communities we have studied? Keyword: Transatlantic Slave Trade
