Remember a hypothesis is an educated guess(and may be wrong), and a good hypothesis is specific.Then summarize what you learned from your research. Include an image of at least one molecule found in this food and briefly describe that molecule in terms of the atoms it is made of and potentially the chemical bonds that keep the atoms together. Is this a beneficial molecule to consume? Explain why. Did your research support your hypothesis? 200words3 describe the theory of endosymbiosis as proposed by Lynn Margulis; (1) describe the theory in general terms; (2) describe what chloroplasts and mitochondria produce in eukaryotic cells (the specific chemical that is produced by electron transport systems in both cases), (3) provide three details from cell biology that support the theory.In one of your two required response posts, select any one of these issues that interests you the most. 200words4 choose and describe one enzyme that is used in cleaning products, other products, industrial procedures or that is found in food. Explain how this enzyme is used. What is the substrate in the chemical reaction? And what is (are) the product(s)?Remember that a chemical reaction converts one or more substrates to one or more products, and that most enzymes are substrate-specific. When looking for enzymes remember that their names end with -ase! 200words5 What is it about the geography and the geology of the Galapagos Islands that make them an ideal place to stimulate ideas about evolution in someone like Charles Darwin?(2) Describe the preparation (academic studies AND practical experience) of Darwin that allowed him to recognize important characteristics that linked populations of animals he studied in the Galapagos Islands to specific niches in their respective environments.(3) Contrast Darwin’s ideas about how populations of organisms can change over time with the ideas of Jean-Baptiste Lamarck.(4) Pick an interesting creature found only in the Galapagos Islands, provide a photo (giving full credit to the source of the photo), and describe the special adaptations of the animal that allow it to survive in the ecosystem where it is naturally found. 250wordsInclude Reference page.
