Contributors to the Carbon Cycle TEACHER’S MANUAL AND STUDENT GUIDE LIFE SCIENCE b Students’ answers will vary, but should demonstrate growth in their understanding of the carbon cycle 2 a Plants perform the roles of photosynthesis and respiration in the aquarium system If plants were removed, then we may predict that carbon dioxide removal by photosynthesis will halt, potentially altering the concentration of dissolved carbon dioxide within the aquatic system As photosynthesis produces oxygen gas as a waste product, the concentration of dissolved oxygen within the aquarium system would be predicted to decrease b In the absence of animal respiration, the only sources of carbon dioxide available to the plant would be from the interchange between the aquarium water and the atmosphere, plant respiration, or microbial decomposition It is possible that the removal of animal-derived carbon dioxide would limit the photosynthetic rate, and therefore growth rate, of aquatic plants within the aquarium dissolved CO2 dissolved O2 CO2 CO2 O2 O2 The Atmosphere photosynthesis (plants, algae) 6CO2 + 6H2O .C6H12O6 + 6O2 6O2 + C6H12O6 . 6CO2 + 6H2O cellular respiration (fish, plants, snails, etc.) dissolving feeding dissolving light source decompositionwaste organic matter fish food old food algae snail fish bacteria aquatic plant Sample Answers to Assessment Questions 1 a Sample aquarium ecosystem model: ©2018 Carolina Biological Supply Company 33 Teacher’s Manual Carolina EcoKits® Contributors to the Carbon Cycle for Chemistry A full year of high school chemistry investigations that provide flexible learning solutions for remote or at school labs Molecular Structure TEACHER’S MANUAL AND STUDENT GUIDE CHEMISTRY 12 ©2018 Carolina Biological Supply Company Molecular Structure Molecular Structure 1 2 3 4 5 6 7 Good gas & moisture barrier properties High heat resistance Clear Hard Tough Microwave transparency PETE Solvent resistant Plastic Type Polymer and Structure General Properties Polyethylene Terepthalate HDPE High-Density Polyethylene V Polyvinyl Chloride LDPE Low-Density Polyethylene PP Polypropylene PS Polystyrene All other resins, layered multimaterials, some containers OTHER Excellent moisture barrier properties Excellent chemical resistance Hard to semi-exible and strong Soft waxy surface Permeable to gas HDPE lms crinkle to the touch Pigmented bottles stress resistant Excellent transparency Hard, rigid (exible when plasticized) Good chemical resistance Long term stability Good weathering ability Stable electrical properties Low gas permeability Tough and exible Waxy surface Soft – scratches easily Good transparency Low melting point Stable electrical properties Good moisture barrier properties Excellent chemical resistance High melting point Hard, but exible Waxy surface Translucent Strong Clear to opaque Glassy surface Rigid or foamed Hard Brittle High clarity Affected by fats and solvents There are other polymers that have a wide range of uses, particularly in engineering sectors.
