BSC 1011C — Generаl Biоlоgy IIMidterm Exаminаtiоn IIModules 8–13 | 75 points Answer all six questions using complete sentences. Explain the biological ideas in your own words and address each part. One short paragraph or a few numbered sentences is usually sufficient for each question. 1. Mosses and Ferns — 12.5 points A moss and a fern are growing in a damp forest. Compare these plants in terms of vascular tissue and which generation—gametophyte or sporophyte—is dominant. Explain why a fern can generally grow taller than a moss. Then explain why both plants need a film of water for fertilization. 2. Seeds, Pollen, and Flowering Plants — 12.5 points A pine tree and a flowering plant grow in an environment with seasonal rainfall. Explain how pollen and seeds help plants reproduce successfully on land. Describe one important reproductive difference between gymnosperms, such as pine trees, and angiosperms, such as flowering plants. What happens during double fertilization in angiosperms, and what two products result? 3. Invertebrate Body Plans — 12.5 points A sea anemone remains attached to a rock, while an earthworm moves through soil. Compare their body symmetry and number of embryonic germ layers. Explain how the body organization of each animal supports its movement or feeding. Identify the phylum to which each animal belongs. 4. Chordates and Vertebrate Evolution — 12.5 points Tunicates, fishes, birds, and mammals belong to the phylum Chordata. Describe two defining chordate characteristics. Explain why an animal can be classified as a chordate even if these characteristics are present only during early development. Choose one vertebrate innovation—jaws, limbs with digits, or the amniotic egg—and explain how it supports feeding, movement, or reproduction. 5. Homeostasis and Temperature Regulation — 12.5 points A person exercising on a warm day begins sweating. A nearby lizard moves into the shade. Explain how sweating helps the person maintain homeostasis and why this response is an example of negative feedback. Identify one animal tissue type involved in the person’s response and explain its role. Then compare endothermy and ectothermy using the person and lizard as examples. 6. Ecological Interactions and Conservation — 12.5 points Researchers observe fewer predators, more deer, and fewer young trees in a forest. Explain how a decline in predators could indirectly reduce the survival of young trees. Identify one density-dependent factor that could limit the deer population. Then propose one conservation or management action that could help young trees become established, and explain the expected biological effect. Grading Rubric Each question is worth 12.5 points, for a total of 75 points. Biological accuracy — 5 points: Biological concepts and terminology are correct. Application and connections — 4 points: The response connects relevant ideas and applies them to the question. Explanation and reasoning — 2 points: The response explains how or why, rather than only stating an answer. Clarity and completeness — 1.5 points: The response is understandable, addresses each part, and uses the student’s own words.
