1.1 The cell is the basic unit of life because 1) it is midway between the biosphere and an organic molecule in size 2) it is the smallest unit capable of exhibiting the fundamental characteristics of life 3) it was discovered by Robert Hooke in 1665 4) it contains the nucleus 5) Dutrochet, Schleiden and Schwann said so more than a hundred years ago 1.2 Which of the following physico-chemical and biological features characterize living organisms? 1) They move by internal forces 2) They take up small organic or inorganic molecules and synthesize large organic molecules so that they can grow from within. 3) They transform one kind of energy into other forms of energy, often by burning organic molecules using oxygen 4) They reproduce with near fidelity 5) All of the above 1.3 Materialism is 1) A philosophy stating that life can only be explained in terms of supernatural forces 2) A philosophy stating that life can be explained in terms of chemistry and physics 3) A philosophy based on water, hydrogen, oxygen and aquosity. 4) A philosophy based strictly on water 5) A philosophy of life championed by Madonna 1.4 Viruses have been thought to have been: 1) the smallest living organism 2) the largest chemical 3) the equivalent of mitochondria 4) the basic unit of life 5) both 1 and 2 2.1 Alexander Fleming’s discovery of penicillin is an example of: 1) planned methodical research 2) systematic testing 3) accident 4) hypothesis testing 5) the scientific method 2.2 Walter Cannon’s discovery of the relationship between emotions and the endocrine system is an example of: 1) planned methodical research 2) systematic testing 3) accident 4) hypothesis testing 5) the scientific method 2.3 Oskar Minkowski’s artificial production of diabetes mellitus is an example of: 1) planned methodical research 2) systematic testing

3) accident 4) hypothesis testing 5) the scientific method 2.4 “Chance Favors a Prepared Mind.” is a famous statement made by: 1) Walter B. Cannon 2) Erico Fermi 3) Hans Bethe 4) Louis Pasteur 5) Oskar Minkowski 2.5 Dimensional analysis is a way to: 1) go from three dimensions to four dimensions 2) go from three dimensions to one dimension 3) go from fewer dimensions to more dimensions 4) go from more dimensions to fewer dimensions 5) convert what you know in one set of units to what do not know in another set of units by using simple algebra and a few conversion factors 2.6 Estimate the volume of blood pumped through the heart in a day using dimensional analysis assuming the volume of blood pumped through the heart in one beat is 100 ml. The heart beats 60 times/minute, there are 60 minutes in an hour and 24 hours in a day. There are 1000 ml in a liter. 1) 144 liters/day 2) 8640,000 liters/day 3) 8640 liters/day 4) 8.64 liters/day 5) 360 liters/day 2.7 Set up an algebraic equation that can be used to estimate the volume of blood in liters pumped through the heart in a day using dimensional analysis. Assumes the volume of blood pumped through the heart in one beat is 100 ml. the heart beats 60 times/minute, there are 60 minutes in an hour, 24 hours in a day and 1000 ml in a liter.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
