Antonie van Leeuwenhoek was the first person to use a microscope and
describe tiny animalcules. What is an animalcule? Describe major
characteristics of an animalcule in terms of microbiology. Describe the size and
living state of these animalcules. Please include: How are animalcules
classified/identified? How do you form these classification groups?

make a drawing of a phylogenetic tree that contains all 3 domains of life. The tree should include at least
three different animals, two plants, chemoheterotrophic bacteria, photoautotrophic bacteria,
chemoheterotrophic archaea, thermophilic archaea and fungi. Identify both primary endosymbiosis events
on the tree and draw a line to connect it to the organism that would become the future organelle.

- Give 5 species of genus agrobacterium. Then make a clade. The clade must observe the rules of constructing a cladogram. Synapomorphies must describe all organisms above it but not below it.arrow_forwardPlease create a phylogenetic (evolutionary) tree given this criteria and follow all points! There are three domains of life - Bacteria, Archaea, and Eukarya. Start by drawing these three main branches. Then add branches for plants, animals, fungi, and protists. When adding all these branches, don't just add them randomly. The branching pattern reflects evolutionary relationships. You should use the relationships/branching patterns. Then add additional branches for • three species of bacteria • three species of archaea three species of plants three species of animals • three species of fungi • three species of protists (single-celled eukaryotes) You can pick any species you want. For each species, be sure to add 1 synapomorphy (shared derived character) that defines the species or group. • Finally, label the tree with all the terms (parts of a tree, not phylogenetic groups) when describing a phylogenetic tree.arrow_forwardFor this assignment you will create a dichotomous key to help you Identify Bacteria (which are a pain in the bum to identify on the species level.) We will be focused on the general terms of bacteria and the only Phylum that will be addressed is the Cyanobacteria. Use the following to create a dichotomous key to begin to identify Bacteria: BACTERIA Bacillus Coccus Spirillium Phylum Cyanobacteria Gram (+) (-) Root nodules To Begin use the following question: Does the organism exhibit a membrane bound nucleus?arrow_forward
- What are the 4 characteristics/properties of rRNA genes which make them good molecular chronometers. Why viruses are not found in the tree of life? Why might viable cell cultures be of more use in microbial taxonomy than preserved specimens? Is it possible to provide a formal name for a microorganism that has not been cultivated in isolation? What kind of name might be used if a microorganism is well-characterized but cannot yet be cultivated in isolation?arrow_forwardIn studying Lokiarchaeota, researchers identified eukaryotic signature genes and used this information to better understand the relationship between archaeans and eukaryotes. Many other types of genetic analysis can be used that focus on certain types of genes. One example of this is multilocus sequence typing (MLST), which focuses on examining genes called housekeeping genes. Microbes encode both housekeeping and pathogenic genes in their genome. Drag the examples of genes to the correct bins to indicate whether they are housekeeping genes, pathogenic genes, or eukaryotic signature genes. Place the phrase describing a gene product in the correct bin. ► View Available Hint(s) peptidoglycan synthesis genes Housekeeping genes membrane remodeling genes cytoskeletal genes membrane lipid genes Pathogenic genes endotoxin genes Reset ribosomal genes exotoxin genes Eukaryotic signature genes Helparrow_forwardChoose the correct answers. Q1: It is a practice of making hypotheses about taxonomic relationships. A. Phylogeny B. Phenetics C. Cladistics D. Phylogenetics Q2: Which of the following statements is true about the protein Cytochrome C? A. Its secondary structure is made up of beta helices B. It is involved in the cellular respiration particularly in glycolysis C. It is involved in the cell’s apoptosis D. It is highly varied among a wide spectrum organism suggesting huge changes throughout the history of life Q3: It is the study of the diversity of life forms and the evolutionary relationships of organisms.

- Molecular phylogenetics can compare the sequence of amino acids in proteins as well as (blank) to identify the characters used to construct a cladogram.arrow_forwardA sample of bacteria is collected from soil in a field that was recently treated with pesticides. The bacteria are classified and a phylogenetic is built to illustrate the soil bacteria diversity. What kinds of characteristics would be best for creating this phylogenetic? a. rRNA gene sequence and amino acid sequence of lipase b. Cell wall structure and physical appearance c. Reproductive rate and susceptibility to pesticides d. Entire genome sequence and protein expression dataarrow_forwardExamine the following phylogenetic tree illustrated in Figure shown in the picture. In general, what does a phylogenetic tree illustrate? How do you compare the relationships of organisms BB, CC, and DD?arrow_forward
- This chapter shows a phylogenetic tree for the three domains of life, which is based on DNA sequence data for rRNA and other genes. Which of the following answers concerning the phylogenetic relationships found within this tree is incorrect? View Available Hint(s)for Part A Euryarcheotes are found in the Archaea Diatoms, Tubulinids, and Euglenozoans belong to the domain Eukarya Forams, Fungi, and Chlamydias belong to the domain Eukarya. Spirochetes belong to the domain Bacteria Ciliates, Red Algae, and Plants belong to the domain Eukarya.arrow_forwardDraw a simpler version of the phylogenetic tree that just depicts the four supergroups of eukaryotes after viewing the image. Now imagine and sketch the tree as if the unikonts were the first eukaryotes to diverge from the rest of the eukaryotes.arrow_forwardRickettsia bacteria always lives as parasites inside eukaryotic cells, ad their genomes are much smaller then those of free living bacteria. Organisms that live only as parasites often have reduced genomes compared to the free living relatives. How could a parasitic lyfestyle contribute to a reduction in genome size?arrow_forward
