BIOLOGY 1010 FINAL EXAM (COMPREHENSIVE)
What are the basic reasons for experiments and how should they be set up?CORRECT ANSWERTests that support a hypothesis must be repeatable and the hypothesis must be falsifiable. Observetions, ?, hypothesis, prediction, experiment.What are the characteristics of life?CORRECT ANSWEROrder, regulation, growth and development, energy processing, reproduction, response to the environment, evolution.What is the difference between covalent and ionic bonds?CORRECT ANSWERCovalent: Electrons are shared. Strongest bond.
Ionic: Electrons are gained or lost.
Hydrogen: Between or within molecules. (weak) found in water, DNA, proteins.
What subatomic particle is involved in these covalent and ionic bonds?CORRECT ANSWERProtons (determines the element), neutrons (determine isotopes), electrons (Determine chemical behavior) What are the four groups of organic compounds? examples of each group.CORRECT ANSWERCarbohydrates (starch, glycogen, cellulose), lipids (fats and oils, steroids, phospholipids) , proteins (enzymes, muscle), nucleic acids (DNA, RNA).What are the building blocks for proteins?CORRECT ANSWERAmino acids What are the building blocks for nucleic acids?CORRECT ANSWERNucleotides 1 / 2
What makes the water molecule so important for life on the planet?CORRECT ANSWERWater molecules stick together: cohesion and surface tension. Water has a strong resistance to change in temperature.Density differences between liquids and ice. Water is a common solvent for life.What is the function of the plasma membrane?CORRECT ANSWERPermeable. Made of lipids and protein. separates the internal environment from the external. Allows for communication between cells and their environment.Function of the ribosome?CORRECT ANSWERSite of protein synthesis.MitochondriaCORRECT ANSWERSite of cellular respiration. Produces ATP.ChloroplastCORRECT ANSWERSite of photosynthesis. Light energy from the sun is turned into chemical energy here then is moved to the mitochondria to make ATP.NucleusCORRECT ANSWERcontrol center of the cell. Contains DNA.DiffusionCORRECT ANSWERPassive transport. , The process by which molecules move from an area of higher concentration to an area of lower concentration OsmosisCORRECT ANSWERPassive Transport. Water is moved to an area of low solute to high solute. Is the diffusion of water across a selectively permeable membrane.ATPCORRECT ANSWEREnergy made in Mitochondria. Adenosine triphosphate. supplies the energy for the cells to do their work.Cellular respiration/ where does it occur?CORRECT ANSWERoccurs in the mitochondria. Process where food is broken down in the presence of oxygen to produce energy for the organism. Glycolysis, Krebs cycle, electron transport.
