It’s Time to Review!! a.k.a: THE TEST IS COMING!

It’s Time to Review!!a.k.a: THE TEST IS COMING! IB:Friday, May 9th(afternoon) and Monday, May 12th(morning) AP:Monday, May 12th(morning)

What’s on the Exam?- • IB: refer to the “IBCourse Guide” • online under “IB/AP Test Review”; at top of the page • Password: panthers • Topics #1-6 (SL); #1-11 (HL) • Options: you will answer all questions for 2 options • “Evolution”; “Neurobiology & Animal Behavior”; only SL can answer “Cells & Energy” • AP: refer to AP Biology Course Framework (online) • AP now has 4 “Big Ideas” • Evolution • Energy & Living Systems (cellular processes) • Processes of Living Systems (genetics) • Interactions

The New AP Format Means… • Increased emphasis on themes & concepts & how they relate, not just facts!

What to bring to the IB exam: • Several sharpened No. 2 pencils (with erasers) for all multiple-choice answer sheets. • Black or dark-blue ballpoint pens for free-response questions in most exams. • Calculator: If graphing calculator, then remove ALL programs!! • NO cell phone, iPod, notes

What to bring to the AP exam: • Several sharpened No. 2 pencils (with erasers) for all multiple-choice & grid-in answers. • Black or dark-blue ballpoint pens for free-response questions in most exams. • Calculator: 4-function (+, -, x, ÷) & square-root capability only • Your social security number for identification purposes. (If you provide it, the number will appear on your AP Grade Reports.) • NO cell phone, iPod, notes, graphing calculators • You will be provided with a list of equations & formulas (see list under AP Review on my website. • May want to bring a watch (without an alarm).

Action Verbs • IB: refer to “Action Verbs” (“Resources”) • AP: refer to “Cliff’s- What’s on the Exam? • Examples: • Define: give the precise meaning of a word or phrase • Discuss: give an account including, where possible, a range of arguments, assessments, of the relative importance of various factors or comparisons of alternative hypotheses • Explain: give a clear account including causes, reasons or mechanisms • Describe: give a detailed account, including all the relevant information • Draw: represent by means of pencil lines (add labels unless told not to) • Analyze: interpret data to reach conclusions

Action Verbs • Suggest: propose a hypothesis or other possible answer • Annotate: add brief notes to a diagram, drawing or graph • Construct: represent or develop in graphical form • Compare(IB): give an account of similarities and differences between two or more items, referring to both (all) of them throughout (can use a table) • Compare (AP): discuss two or more items with an emphasis on their similarities • Contrast(AP): discuss two or more items with an emphasis on their differences

STRUCTURE OF TEST: IB • Paper 1: SL= 45min. & HL= 60min. • CORE CONTENT (aka “TOPICS”) • SL: 30 M/C & HL: 40 M/C • Paper 2: SL= 1hr 15min. & HL= 2 hr 15min. • CORE CONTENT/TOPICS (1 data based question & several short answer questions) • Section A: answer all questions • Section B: answer 1 of 3 if SL and 2 of 4 if HL • Paper 3: SL= 1hr & HL= 1 hr 15min. • 2 “OPTIONS”- (we have learned all content in “Evolution” & “Neurobiology & Animal Behavior”) • SL: choose 2 options and answer all short answer questions from that option (can also choose “Cells & Energy”) • HL: choose 2 options and answer all short answer questions & the one extended response question from that option

STRUCTURE OF TEST: AP **Designed to obtain a mean score of 50% • Section I: M/C: 90min.  50% of score • Part A: 63 M/C • “regular” & questions dealing with experiments or data • Part B: 6 grid-in questions • No penalty for wrong answers!! • Essays: 10min. to read and 80 min. to write  50% of score • 2 long free-response questions • Have about 20 minutes for each • 6 short free-response questions (few sentences to a paragraph) • Have about 6 minutes for each

HINTS • Don’t let easy questions mislead you • Budget time: skip hard questions and come back to them • Try to eliminate answers • Give specific information in essay answers (terminology & biological process explanation) • (AP) Answer each part of essay separately (skip a line/ new paragraph; if question has a, b, c parts- answer should have a, b, c sections) • Don’t write a formal English style essay BUT use complete sentences and punctuation  get to the point! • Remember your direction/action words

PRACTICE MULTIPLE CHOICE: IB (SL) • Which part of an amino acid does the amino (-NH2) group of another amino acid react, in order to form a peptide linkage? • Carboxyl group (-COOH) • Amino group (-NH2) • Hydrogen (-H) • Side chain (-R)

PRACTICE MULTIPLE CHOICE: IB (HL) • The diagram below summarises the light-dependent reactions in photosynthesis. What is occurring at X? • ADP + Pi ATP • NADP+ NADPH + H+ • H2O  O2- + 2 H+ • NADPH + H+  NADP+

PRACTICE SHORT ANSWER-IB (paper 2 section A) • A) --- this question is no longer part of the curriculum • B) Compare the conditions which allow exponential growth of a population with those that cause the population to remain at a plateau (5) • C) Explain how species can evolve by natural selection (8)

ANSWER KEY (MARKSCHEME) • B) 5 points max

ANSWER KEY (MARKSCHEME) • C) 8 points max • Sexual reproduction produces variation in the genotypes of individual offspring; • Variation of genotypes can result in variation of phenotypes; • Populations tend to produce more offspring than the environment can support; • Causing competition; • Environments can change at any time; • Some individuals are adapted because of their phenotypes; • Will out-compete other individuals less favorably adapted; • Enables greater survival rate for those better adapted;

ANSWER KEY (MARKSCHEME) • C) 8 points max- CONTINUED • Process called natural selection/ selective advantage; • Increased survival can result in reproductive advantage; • Favoring the enhancement of alleles relating to better adapted phenotypes; • Causes changes in gene pool over time; • Resulting in evolution of species
