Biology EOC For Cassie Questions With Complete Solutions

If a company claims that its product has proven scientifically, which of the following should have taken place if the results are to be considered reliable? correct answer: Results should have been peer reviewed and repeated producing the same findings a student is conducting an investigation to determine the effect of temperature on the metabolism of yeast (saccharomyces cerevisiae). yeast and sugar are added to water, the gas produced is captured, and its volume is recorded. Which variables should be held constant during this investigation? correct answer: mass of yeast and mass of sugar based on your knowledge of scientific investigations, which stage of scientific investigation did the invention of the microscope significantly advance? correct answer: gathering the data for the investigation scientific law and scientific theory are similar In that both correct answer: represent a large amount of scientific investigation and evidence which of the following best describes a result of the polar nature of water molecules? correct answer: ionic compounds dissolve easily in water to help patients replenish bodily fluids quickly during an illness, doctors need to understand how cells behave in their environment. doctors have confidence in what they know about how cells behave because correct answer: cell theory has been tested, refined, and observed to be true over hundreds of years in which of the following circumstances would it be most likely for large organic molecules to form during a laboratory experiment correct answer: if RNA segments that could act as catalyst formed water has a much higher specific heat than most other covalent compounds. what do you predict might happen if water has a low specific heat instead? correct answer: organisms that are sensitive to changes in temperature would die assume a group of scientists has managed to set up an experiment stimulating the conditions of early Earth that resulted in a cell with DNA using RNA to produce proteins from amino acids as modern cells do. What conclusion could they draw from this experiment? correct answer: it is possible for a cell similar to a modern cell to form under the conditions of the experiment which of the following best compared the structures of lipids and carbohydrates? correct answer: both consist of carbon, hydrogen, and oxygen, but carbohydrates have repeating structural units and lipids do not a variety of organic molecules have been found in meteorites that have landed on earth, including individual amino acids and lipid molecules. to date, however, no microspheres have been found on these meteorites. why is it unlikely that microspheres will ever be found on a meteorite even though lipids can form in them? correct answer: groups of lipids will only forms into microsphere when they are in liquid water some proteins catalyze biochemical reactions. if a genetic defect prevented a protein catalyst from being produced, which of the following do you predict would happen in the cell? correct answer: the reaction the protein catalyzes would proceed very slowly or not at all which of the following best describes the difference between the functions of nucleic acids and enzymes? correct answer: nucleic acids contain the genetic code for protein synthesis, while enzymes catalyze chemical reactions
