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...

JMU BIO 150 Exam 2 Define macroevolution ️evolutionary change above the species level, including the origin of a new group of organisms or a shift in the broad pattern of evolutionary changes over time How do we identify a species? ️groups of actually or potentially interbreeding populations that are reproductivley isolated from other such groups Define reproductive isolation ️cannot produce viable offspring Define viable ️offspring can reproduce Define speciation ️splitt...

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? - ...

What is microevolution? - ️️The change in allele frequencies that occurs over time within a population. What is macroevolution? - ️️Major evolutionary changes over time, the origin of new types of organisms from previously existing, but different, ancestral types. What is a species? - ️️A group of populations whose members possess similar anatomical characteristics and have the ability to interbreed. What is allopatric speciation? - ️️The formation of a new species in po...

bio 181 exam 1 (kosal)Compare and contrast the different mechanisms of speciation (allopatric, sympatric, parapatric, peripatric). - correct answer -Allopatric speciation takes place when populations are geographically isolated. Volcano explodes and populations are divided. -Sympatric occurs without geographic isolation. Occurs through the process of polyploidy: producing individuals with more than two sets of chromosomes. It is a genetic change within a population. -Parapatric speciation ...

How chromosomes were inherited c. That genetic mutation could be responsible for making new alleles d. That genes were t...
