MARIELLE HOEFNAGELS. THIRD EDITION<\/h4>\n<p>(CHAPTER1) Imagine that you are a scientist working with one of the first research teams sent to the planet Mars. One day, while digging in one of your research plots, you discover something new in the soil. You think it might be alive!<br \/>\nHow will you determine whether it is alive or not?<br \/>\nHow will you know whether it is a prokaryote or a eukaryote?<br \/>\nHow will you determine in which of the three Domains of life it might be classified?<br \/>\nExplain how energy enters and travels through most living systems on Earth.<br \/>\nWhat is the original source of the energy?<br \/>\nHow is energy transferred within living systems? You may answer in written text and\/or by drawing and labeling a diagram of a generalized system.<br \/>\nWhy are there always more primary producers than there are consumers in living systems?<br \/>\nInclude the following terms in your answer: autotroph, heterotroph, decomposers, primary producers, primary consumers, secondary consumers.<br \/>\nExplain why photosynthesis and aerobic respiration are considered to be opposite reactions. Use the following terms in your explanation: exergonic reaction, endergonic reaction, potential energy and kinetic energy.<br \/>\nHypothesis testing and experimental design:<br \/>\nState an observation about your environment.<br \/>\nList three hypotheses (ideas that you can test) that might explain the mechanism(s) responsible for the phenomenon that you observed.<br \/>\nChoose one of those hypotheses to test. State your null hypothesis.<br \/>\nDesign an experiment or a set of observations that you could perform to test your chosen hypothesis.<br \/>\nWhat would your control group be?<br \/>\nWhat would your treatment group(s) be?<br \/>\nWhat variables would you standardize?<br \/>\nWhat variables would you measure?<br \/>\nWhat would the outcome of your experiment be if your hypothesis is correct?<br \/>\nWhat would the outcome of your experiment be if your hypothesis is incorrect?<br \/>\nHow can a failed checkpoint during the cell cycle result in cancer? Describe some of the mistakes that can result if a checkpoint fails at each of the following stages of the cell cycle:<br \/>\nGap Phase 1:<br \/>\nSynthesis Phase:<br \/>\nGap Phase 2:<br \/>\nMetaphase of Mitosis:<br \/>\nWhy is sexual reproduction so costly? If sexual reproduction is so costly, why do so many organisms have sex?<br \/>\nDraw a pair of un-replicated homologous chromosomes.<br \/>\nImagine that you are a herpetologist (i.e., a scientist who studies reptiles) working in West Texas. You specialize in studying checkered whiptail lizard species, some of which reproduce sexually and some of which reproduce asexually. The asexual species are thought to have arisen from a hybridization event between two sexual species. One day you come across what you think is a new species of checkered whiptail lizards. It appears to reproduce asexually, but after some lab work, you discover that it does NOT replicate its DNA twice before undergoing meiosis like some of the other asexual species do. You also observe that the offspring of these asexual lizards still have the same number of chromosomes as their parents. What else could these lizards be doing (besides two rounds of DNA replication prior to meiosis) to reproduce themselves without reducing the number of chromosomes in their offspring?<br \/>\nDraw and label a normal sexual reproductive life cycle.<br \/>\nDraw and label your hypothesized asexual reproductive life cycle for the newly discovered lizard species.<br \/>\nIf you have a plant that expresses a dominant trait, how can you determine its genotype?<\/p>\n<p><center><a href=\"http:\/\/onlineclassesguru.com\/orders\/ordernow\"><img decoding=\"async\" src=\"https:\/\/encrypted-tbn0.gstatic.com\/images?q=tbn:ANd9GcTyj99p60XCLyLk1htB7-1neRt8-2QdnenNlQ&usqp=CAU\"target=\"_http:\/\/onlineclassesguru.com\/orders\/ordernow\"\/><\/center><p>","protected":false},"excerpt":{"rendered":"<p>Explain how energy enters and travels through most living systems on Earth.
