Problem 56

Birthrates 2009 The table shows the number of live births per 1000 women aged 1544 years in the United States, starting in 1965. (National Center for Health Statistics, www.cdc.gov/nchs/) a) Make a scatterplot and describe the general trend in Birthrates. (Enter Year as years since 1900: 65, 70, 75, etc.) b) Find the equation of the regression line. c) Check to see if the line is an appropriate model. Explain. d) Interpret the slope of the line. e) The table gives rates only at 5-year intervals. Estimate what the rate was in 1978. f) In 1978, the birthrate was actually 15.0. How close did your model come? g) Predict what the Birthrate will be in 2010. Comment on your faith in this prediction. h) Predict the Birthrate for 2025. Comment on your faith in this prediction

Step 1 of 3

Biology 130 : Exam 3 Diversity of Life Diversity of Life : total of all variations in forms, functions, and behaviors. Biodiversity : number of all the surviving species in the world. Number of species increases due to evolution and decreases due to extinction. CLASSIFICATION OF LIVING ORGANISMS ­Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Living organisms are currently classified in to 3 domains and 6 kingdoms. Kingdoms are Archaebacteria, Eubacteria, Plantae, Animalia, Fungi, Protista. Domain Archaea­Prokaryotic ­Kingdom Archaebacteria Has many ancestral characteristics –Cell wall type 1 Can survive in extreme conditions Domain Bacteria­Prokaryotic ­Kingdom Eubacteria It’s the typical bacteria – Cell all type 2 Domain Eukarya­Eukaryotic ­ Kingdom Protista – Most no cell wall, mostly single celled organisms ­ Kingdom Plantae­ cellulose cell wall, multicellular metazoans, producers ­ Kingdom Animalia­ no cell wall, multicellular metazoans, consumers ­ Kingdom Fungi –Chitin cell wall, mostly multicellular metazoans, decomposers *Prokaryotic : Before+Kernel – No nucleus, no membrane bound organelles. *Metazoan = multicellular organism that has to have all of its cell types to survive Body shape of bacteria related to name: Spherical shaped­coccus Rod shaped­ bacillus Spiral shaped­ spirillum Form chains = strepto Form sheets = staphylo ­Earliest antibiotics discovered were produced by bacteria and fungi. Harmful bacteria: Streptococcus, Staphylococcus, Clostridium (Tetanus/ botulism), Rickettsia (Rock Mountain Spotted Fever), Borrelia (Lyme disease). ­Viruses are non living and non cellular. Cannon reproduce without using a host cell ( the reason why it is non living). Non domain no kingdom. Can evolve because they have DNA and RNA. Smaller than bacteria (30­100 nanometers). Kingdom Protista ­Mostly single celled, eukaryotic, most found in water, Have to have moisture, highly diverse. Major groups ­Amoeba­like cells­ move with pseudopods. Ex) Amoeba, Foraminifera. ­Cells with cilia­ Paramecium, Stentor. ­Cells with flagella: Giardia, Euglena (protest that undergoes photosynthesis) Some are intracellular parasites. Plasmodium and Toxoplasma. ­Plasmodium causes malaria. ­Toxoplasma travels around in animal feces. (Carnivore and omnivore.) Causes birth defects. Some are plant­like protistans: Rhodophyta and Phaeophyta
