Thank you for inquiring your data to our organization. We have completed an inventory of the biological diversity in Central America and interpreted the distribution of the Choloepus hoffmanni (two-toed sloth) and Bradypus variegatus (brown-throated three-toed sloths). The possible locations the sloths could be located are‚ agriculture (AG)‚ low land old growth (LL OG)‚ low land secondary forest (LL SF)‚ mountainous old growth (MTN OG)‚ mountainous secondary forest (MTN SF)‚ and finally clear cut

(Ch. 12‚ Section “How Are Marine Organisms Classified?”) Plankton Plankton is a organism that float. Why is a copepod‚ which can swim and propel itself through the water‚ classified as plankton? (Ch. 12‚ Section “Plankton”) Because of its small size‚ it cannot swim very far or fast so its location

EVOLUTION and NATURAL SELECTION (30 pts) a. What is a mutation? Provide 3 examples of different mutations causing specific diseases in human population. For each example explain what kind of mutation that is (ie. A point substitution‚ a chromosomal duplication etc). Mutation is a genetic mistake(s) that occur during DNA replication. 1. Progeria accelerated aging; mutation in the LMNA gene 2. Hypertrichosis excessive hair on the shoulders‚ face and ears; implicate it to a rearrangement

BIOLOGY ‘S ASSIGNMENT 1/What is the purpose of digestion? * Break down food‚ absorb nutrient from food into body tissues and systems in body 2What is the name given to mammal only eat meat ? * Carnivores 3/What is the name of mammal only eat plant? * Herbivores 4/What is the difference between a fore-gut fermenter and hind-gut fermenter? Example? Because plant cells have tough cellulose cell walls and herbivore are not able to digest‚ they use micro- organisms that live symbiotically
