AP Biology Exam Questions and Answers Graded A+ What are the 2 theories of evolution? Explain each Gradualism- geologic changes result from slow, gradual, continuous process Punctuated Equilibrium- Long period of stasis punctuated by short bursts of significant change. What was Lamarck's theory and why was it wrong? Lamarck = Inheritance of Acquired characteristics- traits acquired during lifetime could be passed on What is natural selection Comptetition for limited resources re...

A certain species of sea otters lives off the coast of Alaska. Some have the ability to tolerate the colder waters farther north while others stay in the central coastal area. As a result of a large oil spill along the northern coast, most of the otters living in those colder waters die. Afterwards, the population of otters, in general, is now less tolerant of cold water. What is this an example of? A.) allopatric speciation B.) hybrid sterility C.) bottleneck effect D.) sympatric specia...

Micro-evolution - Answer-- a change in an evolution's gene pool over a succession of generations - changes in allele frequencies within populations - often associated with adaptation - can be measured from one generation to the next Macro-evolution - Answer-- major changes in the history of life - origin of new species - generates biological diversity Species - Answer-A population or group of populations whose members have the potential to interbreed with one another in nature to produc...

What is micro-evolution? - Changes in allele frequencies within populations, often associated with adaptation, can be measured from one generation to the next "small changes" What is macro-evolution? - Major changes in the history of life, origin of new species, generates biological diversity "big changes" What is a species? - a group of populations whose members have the potential to interbreed with one another in nature to produce fertile offspring What is allopatric speciation? - ...

Darwin’s theory of evolution is a strong theory, but at the time of proposing the theory, some aspects were yet to be explained. Which of the following things below did Darwin understand and incorporate into his theory? a. That inherited variations could increase an organism's ability to survive and reproduce b. How chromosomes were inherited c. That genetic mutation could be responsible for making new alleles d. That genes were the templates for making proteins a. That inherited varia...
