Sample High School Questions 1. This connective tissue protein is the structural component of bones, tendons, ligaments, and skin. The tanning process preserves this protein in animal skins to form leather. Identify the protein that forms gelatin when boiled. COLLAGEN [kol-uh-juhn] 2. This agranular leukocyte [loo-kuh-sit] matures in the thymus [thahy-muhs] and may be further classified as either cytotoxic [sahy-tuh-tok-sik] or helper varieties. Identify the type of white blood cell that typically targets virally infected or cancerous cells. T CELLS (ACCEPT: T LYMPHOCYTE) 3. This division of plants shows alternation of generations where the dominant photosynthetic phase consists of the gametophyte [guh-mee-tuh-fahyt]. These are the simplest of terrestrial plants, lacking complex tissue organization. Identify the nonvascular plant division that consists of hornworts, liverworts, and mosses. BRYOPHYTA [bry-o-phy-tuh] 4. These non-flowering, vascular plants make up the division Filicophyta [fil-i-co-phy-tuh]. Gameotphytes [guh-mee-tuh-fahyts] of this plant are commonly referred to as prothallia/ [proh-thal-ee-uh]. Identify the type of plant whose young leaves unroll from a crosier [kroh-zher], or fiddlehead. FERN 5. These flower structures, along with the petals, make up the perianth [per-ee-anth], or floral envelope. These structures are usually greenish and resemble reduced leaves. Identify the flower structures collectively known as the calyx [kal-iks]. SEPAL(S) [see-puhl] 6. The size and shape of this flower structure results in flowers being classified as either actinomorphic [ak-tin-oh-mawr-fik] or zygomorphic [zahy-guh-mawr-fik]. The parts of this structure may be separate or marginally fused together. Identify the flower structure that is composed of the petals. COROLLA [kuh-rol-uh] 7. This class of soft, slimy fish have elongated bodies to aid in their burrowing habit. Identify the class of jawless fish which contains lampreys and hagfish. AGNATHA [ag-nuh-thuh] 8. In this field of modern chemistry, scientists maneuver atoms one by one using scanning tunneling microscopes. One goal of this field is to build circuits by lining up individual atoms for quantum computers. Identify this field that focuses on the manipulation and manufacture of materials and devices on the atomic scale. NANOTECHNOLOGY 9. This molecule was first discovered by Richard Smalley, Robert Curl, and Harold Kroto. This fundamental new form of carbon consists of 60 carbon atoms. Identify this truncated icosahedrons that is named for the creator of the geodesic dome. BUCKMINSTERFULLERENE [buhk-min-ster-fool-uh-reen](ACCEPT: BUCKYBALL)
