1. You are studying a biopsy of a patient with an infection in their brain. You place a sample under the microscopy and discover some non-human looking cells. The cells don't look like neurons, but do include a clearly identifiable nucleus. To which of the following taxonomic groups do the cells belong? Group of answer choices either bacteria or archaea cyanobacteria either eukaryotes or bacteria eukaryotes archaea 2. Which of the following structures is exclusive to eukaryotes, meaning you won’t find it in bacteria or archaea? Group of answer choices a cell wall endomembrane system ribosomes DNA 3. Which of the following statements is true of BOTH eukaryotes and prokaryotes? Group of answer choices both contain a nucleoid both contain internal membranes both contain a phospholipid membrane surrounding the cell Both contain endoplasmic reticulum both contain a nucleus 4. Acid hydrolases are special proteins in the cell that function at pH 5, and break down macromolecules. Where would you expect to find acid hydrolases? Group of answer choices the cytosol / cytoplasm nucleolus inside the smooth endoplasmic reticulum lysosomes inside the rough endoplasmic reticulum the golgi 5. Which of the following cellular structures are composed (at least in part) of a biological membrane, itself composed of a bilayer of phospholipids? Group of answer choices peroxisome smooth endoplasmic reticulum vesicle golgi apparatus ribosome nucleolus nucleus ribosomal proteins
