Independent variable Place the following terms in proper order to show biological organization from the most to least complex. Organism, biosphere, tissue, community, cell, molecule, organ biosphere→community→organism→ organ→tissue→cell→molecule The body temperature in humans is maintained around 37°C. Which characteristic of life does this statement represent? . homeostasis A kernel of corn contains an embryo plant that is capable of becoming a complex plant with roots, stalks, leaves and ears of corn. This potential reflects which property of life? Growth & Development 11.12mm converted to micrometers(µm). 11,120 µm The maximum population size that a particular environment can support. The “K” factor. Carrying capacity Secondary or “old field” succession begins with established ________. soils When the concentration of a toxin increases as it is moved up the food chain. Biological magnification Which of the following represents an organism that could be a decomposer? E Which of the following represents an organism that could be a carnivore ? C The term used to describe when one species in a relationship benefits but the other is neither helped nor harmed. commensalism Floods would be considered what kind of limiting factor? Density-independent Using different aspects of the same resource to allow similar species to exist. Resource partitioning The maximum population size that a particular environment can support. The “K” factor. Carrying capacity No two species can occupy the same niche at the same time Gause’s Competitive Exclusion Principle 12 and 6C 14 6C These are isotopes. What varies between the two? neutrons What is the maximum number of covalent bonds an element with atomic number 6 can make with hydrogen? 4 Because oxygen is more _______ than the 2 hydrogens in a water molecule, oxygen establishes a partially negative charge and hydrogen a partial positive charge. Electronegative 3 What is the charge of the green ion if the hydrogens from H2O face it? negative Two or more molecules having the same number and type of atoms but different arrangement. isomer What are the two functional groups found in all amino acids? Carboxyl and amino Saturated fatty acid Name the carbohydrate found in the exoskeletons of Arthropods. Chitin Draw a molecule of oxygen, showingTime its . electron configuration..
