Essential Knowledge + Science PracticeEssential Knowledge 2.B.3:

Eukaryotic cells maintain internal membranes that partition the cell into specialized regions.

Science Practice 6.2:The student can construct explanations of phenomena

based on evidence produced through scientific practices.

Learning Objective 2.13:The student is able to explain how internal membranes

and organelles contribute to cell functions.

Sample Multiple-ChoiceMembrane-bound organelles have been an important component in the evolution of complex, multicellular organisms. Which of the following best summarizes an advantage of eukaryotic cells having internal membranes?

A.Eukaryotic cells are able to reproduce faster because of the presence of organelles.

B.Some organelles, such as mitochondria and chloroplasts, are similar to prokaryotic cells in structure.

C.Organelles isolate specific reactions, increasing metabolic efficiency.

D.Compartmentalization leads to a higher mutation rate in DNA, which leads to more new species.

Sample Grid-InIn a certain species of flowering plant, the

purple allele P is dominant to the yellow allele p.

A student performed a cross between a purple-flowered plant and a yellow-flowered plant. When planted, the 146 seeds that were produced from the cross matured into 87 plants with purple flowers and 59 plants with yellow flowers.

Calculate the chi-squared value for the null hypothesis that the purple-flowered parents was heterozygous for the flower-color gene. Give your answer to the nearest tenth.

Multiple-Choice StrategiesPacing is important! Give yourself about 1 min. per

multiple-choice and about 3 min. per grid-in.NO penalty for guessing!! NO penalty for guessing!! Answer every questionAnswer every question..If calculations are required and more time is needed,

skip it and come back to it later. (Make a mark in test booklet next to question to answer later.) Do the same with questions you can’t answer.

Lab-set questions are tedious. Skip the diagram/data, skim the question first, then go back to the diagram/data to seek the information.

Underline key words such as NOT or EXCEPT.

Multiple-Choice StrategiesRead each answer choice before making a final

selection.Use process of elimination! Cross out letters of

incorrect choices in test booklet. Narrow it down.If you absolutely don’t know it, GUESS! Don’t leave

anything blank!If you finish early, go back over as many items as

possible to catch careless errors.

Free-Response QuestionsIf there are several parts, answer in sequence.Write an essay! No bullet points or outlines.Diagrams: Label them!Calculations: Show your work and each step!

Remember UNITS.“Buzz words”: Define or describe them!If you can’t remember a term, describe/define it.Don’t leave any part of essay blank. Each point

is worth 2X a multiple-choice point.If time allows, proofread your essays!Be kind to Readers: use good handwriting

College Board Comments about new AP Biology Exam

1,200 college students were administered redesigned AP Biology exam questions this spring; their work was scored at the AP Reading. College professors also took the full redesigned AP Biology exam themselves & evaluated each question to set the pts needed for 2,3,4,5. Most AP Biology students earned enough pts to get a 2,3,4, but very few scored well enough on the grid-ins and free-response to score a 5.

College Board Comments about new AP Biology Exam

AP Biology grid-in questions require students to use mathematics to solve biological problems. The avg score on these was very low: 36%.

Multiple-choice: last year, students earned 63% correct on average; this year, 61%

FRQs require students to "explain," "describe," "justify" their content knowledge. Very low scores on avg.
