SOPHIA_HUMAN_BIOLOGY_UNIT_1_MILESTONE 2020 - Southern New Hampshire University HUMAN BIOLOGY UNIT 1 MILESTONE 1 What type of lipid is made up of a glycerol molecule and three fatty acid side chain... s? • Saturated fat • Phospholipid • Triglyceride • Sterol CONCEPT Lipids 2 Which of the following characteristics is shared by all organisms? • Division into multiple sexes • Cycles of consciousness and sleep • Being made up of multiple cells • The ability to grow and reproduce CONCEPT Organisms 3 Which of the following is a component of cell membranes and includes a hydrophilic head, a glycerol backbone and two fatty acid tails? • Phospholipids • Nucleic acids • Triglycerides https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.com• Fatty acids CONCEPT Plasma Membrane 4 Which of the following describes a disaccharide? • It has many sugar units. • It can have up to two sugar units. • It has no sugar units. • It is also an oligosaccharide. CONCEPT Carbohydrates 5 What is chromatin? • A cell organelle that houses the DNA and controls activity within the cell • A condensed form of DNA that occurs when the cell is dividing • A form of uncondensed DNA found within the nucleus of the cell • A structure found within the nucleus that produces subunits of ribosomes CONCEPT Nucleus 6 How does facilitated diffusion differ from simple diffusion? • Facilitated diffusion requires the use of transport proteins. Simple diffusion does not. • https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.comFacilitated diffusion is when molecules are moving from an area of high concentration to an area of low concentration. • Facilitated diffusion requires the use of sodium-potassium pumps. • Facilitated diffusion and simple diffusion are the same thing. CONCEPT Facilitated Diffusion 7 Which of the following is part of the cytoskeleton? • Macrotubules • Macrofilaments • Microfilaments • Intermediate tubules CONCEPT Cytoplasm 8 How many turns of the Krebs cycle are required to break down one molecule of glucose? • Two • Three • Four • One CONCEPT Krebs Cycle 9 https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.comWhat is true about the electron transport chain (ETC)? • A build-up of potassium on the inner membrane of the cell causes a gradient which leads to the production of ATP. • Only products from the Krebs cycle are utilized in the electron transport chain. • The electron transport chain takes place in the nucleus of the cell. • Most ATP is produced during this step of cellular respiration. CONCEPT Electron Transport Chain 10 Which of the following is part of a nucleotide? • Proteins • DNA • Amino acid • Sugar CONCEPT Nucleic Acids 11 Which of the following statements is true? • Human beings are made up entirely of cells. • The parts that make up cells are themselves living things. • For all cells, the nucleus is the control center. • Not all cells have cytoplasm. https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.comCONCEPT Cell Theory 12 In which kind of cells is the Golgi body found? • All cells • Only prokaryotic cells • Some eukaryotic and some prokaryotic cells • Only eukaryotic cells CONCEPT Golgi Body 13 What is true regarding phosphorylation? • It involves combining glucose molecules in order to be used as fuel for glycolysis. • It occurs when ATP donates one of its phosphate groups to a molecule of glucose during glycolysis. • It helps transfer energy from the glucose molecule to a molecule of ADP in order for glycolysis to be carried out. • It strips ATP of all of its phosphate groups. CONCEPT Glycolysis 14 Chloe is studying the effect a certain kind of fungus has on bacteria. Which of the following could be her hypothesis? • "I predict that the bacterial cultures in which I place this fungus will not grow." https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.com• "I notice that when a certain fungus is present in a bacterial culture, the bacteria do not grow." • "I propose that this fungus somehow kills bacteria." • "Based on many tests, I realize that this fungus kills bacteria." CONCEPT Scientific Method 15 Which of the following sources of information is most credible? • A remark made by a registered nurse over dinner • A lecture given by a prominent biologist on the findings of his most recent study • A claim made by a reporter on the evening news • A Wikipedia article on molecular biology CONCEPT Evaluate Information 16 At what level of protein structure are several amino acid chains joined together? • Secondary • Quaternary • Tertiary • Primary CONCEPT Proteins 17 https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.comSome chemical reactions within cells break down molecules. Others make larger molecules. They are all an example of ___________. • metabolism • anabolism • ATP production • catabolism CONCEPT Metabolism 18 Why are mitochondria called the "powerhouse" of a cell? • They convert energy into oxygen. • They convert food into energy. • They convert water into oxygen. • They convert light into food. CONCEPT Mitochondria 19 What role do sensory receptors play in feedback loops to maintain homeostasis? • Respond to stimuli • Interpret stimuli • Detect stimuli • https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.comReverse the effects of stimuli CONCEPT Homeostasis 20 Which of the following statements is true? • Diffusion involves the movement of molecules in the cytoplasm. • Diffusion involves the movement of molecules into or out of a cell. • Diffusion involves the movement of molecules using transport proteins. • Diffusion involves the breaking down of dead organelles. CONCEPT Diffusion 21 Which of the following contains the endoplasmic reticulum, Golgi bodies and the nuclear envelope? • The rough ER • The lymphatic system • The endomembrane system • The Golgi apparatus CONCEPT Endoplasmic Reticulum 22 Which of the following statements about enzymes is true? • Any enzyme in your body is capable of taking part in any type of reaction. • An enzyme can act to either join substrates together or break them down. https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.com• The substrate will be physically different, but not chemically different after being acted upon by an enzyme. • Enzymes most often help to slow down reactions in the body. CONCEPT Enzymes 23 A tonicity with a high concentration of solutes is said to be _________. • isotonic • hypertonic • selectively permeable • hypotonic CONCEPT Osmosis https://www.coursehero.com/file/63362816/HUMAN-BIOLOGY-UNIT-1-MILESTONEpdf/ This study resource was shared via CourseHero.com Powered by TCPDF (www.tcpdf.org) [Show More]
