1 Regents Review Part 2

2 Some Suggestions (again)
Read the question twice. This is NOT a race. Read the info regarding the question. LOOK at everything in the diagrams. Do NOT easily (quickly) make assumptions. Think of your answer before you read the choices Read ALL the choices. Read each choice to the end of the sentence. Be aware of the possibility of trickery!

26 The Flow of Genetic Information
Sequence of bases in DNA determines the Sequence of bases in RNA Sequence of amino acids in Protein

27 What does the sequence of bases in DNA code for?
What cell would this change occur in if it is to be passed on to offspring? What could result from this change?

28 (cancer, sickle cell anemia etc.)
Genetic Disease (cancer, sickle cell anemia etc.) Genetic Variation Why are mutations Important? New Traits Study of genes (e.g. knockout mice) Evolution

34 Match Molecule A with Molecule B:
A B Hormone Antigen Enzyme Receptor Antibody Substrate Neurotransmitter

35 What is the biological catalyst?
What life process is shown? What life process would it be if the arrows were reversed?

36 glycogen, starch, carbohydrate lipid (triglyceride)
What would the final molecule be if the original molecules are: amino acids simple sugars fatty acids and glycerol nucleotides protein glycogen, starch, carbohydrate lipid (triglyceride) DNA, RNA (nucleic acids)

37

38 Why is insulin important?
How does insulin accomplish its function? What kind of molecule is insulin? What organ is X? What process does the dotted arrow represent? What is the function of glycogen? What molecule is glycogen similar to? What organs contain glycogen?

Problem Cause Solution Alternative energy sources; Scrubbers remove SO2 Acid Rain Global Warming Ozone Layer Depletion Deforestation SO2 from burning coal Greenhouse gases (CO2, methane and others) from burning fossil fuels, cattle Alternative energy sources; Energy Conservation; Remove, bury CO2 CFCs Ban CFCs Construction Materials; Cattle raising Human population growth Recycle; reduce consumption Eat less meat Population Control

95 Overharvesting, Exploitation Invasive Species Habitat Conservation;
Problem Cause Solution Loss of Biodiversity Invasive Species Dead Zones (no oxygen in water) Loss of Habitat Overharvesting, Exploitation Invasive Species Habitat Conservation; Laws; Species Conservation; Biological Control Importation of alien species Biological Control Thermal pollution Algae Blooms from fertilizer runoff Raw sewage Cool water? Use less fertilizer or modified fertilizer (less phosphorus) Sewage treatment
