Draw a simple cladogram illustrating the relationships among the following: Common ancestor of all organisms, domain Eukarya, domain Bacteria, domain Archaea. To which domain do the organisms informally known as protists belong? To which domain do you belong?
If you visit a lake in the middle of the Amazon and take water samples to analyze under a microscope from a nearby university that has good instrumentation and there you detect microorganisms that are not visible to the naked eye. What studies would you do to determine if they are bacteria, archaea, fungi or protozoa? Explain each type of analysis and how would you rule out members of each group?

- For instance, you encountered an unusual one-celled organism, what part/s of its cell would you use as reference to classify it under the three domains, specifically if this single-celled organism is an Archaean, Bacteria, or Protist?arrow_forwardWhat would you try to do in order to “separate” the different kinds of organisms from each other (protists, fungi, bacteria, etc)?arrow_forward1) The Miller-Urey experiment in 1953 proved that Group of answer choices multicellular organisms can evolve from unicellular ones living cells could arise from non-living substances organic molecules important to living things could form from a "hot soup" of simple substances conditions on early Earth were not as inhospitable as biologists of the time generally believed a source of energy was not required in order for life to develop on Earth B) Which of the following statements about protists is false? Group of answer choices Some protists are mixotrophic Certain protists share a common ancestor with land plants Some protists are photosynthetic prokaryotes which are similar to the ancestral chloroplast Protists are a polyphyletic group of organisms that often bear little resemblance to each other Although most protists are unicellular, some protists are multicellular as wellarrow_forward
- A scientist has discovered a new species and is tasked with identifying which of the kingdoms of life the organism might fit. Multicellular with nuclei Presence of a cell wall containing chitin Heterotrophic Non-motile Question options: Fungi Protista Plantae Animalia Protists are a group of organisms that are eukaryotic. However, they are a diverse group, with some of the members of the group having a more recent common ancestor with plants while others have a more recent common ancestor with animals. Algae are protists that are more closely related to plants than any other group. Which characteristics would algae share with plants but NOT with animals?

How do fungi get their food? ________________________________________________ Why are plants and fungi placed in separate kingdoms? _______________________________________ How has technology affected classification? _________________________________________________ You are a taxonomist who has just discovered a new organism and you have to place it into one of the kingdoms. The organism seems to make its own food by utilizing its chlorophyll. The organism is only one cell big and is capable of moving freely. In addition to chlorophyll, the organism has several other organelles, including a nucleus. Which kingdom does your organism belong to?
