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...

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? Speci...

Acute - Sharp or severe having a rapid onset and short duration. All-Hazard Concept - Provides a coordinated approach to a wide variety of incidents; all responders use a similar, coordinated approach with a common set of authorities, protections, and resources. Atypically Stressful Event - Term used in National Fire Protection Association (NFPA) standards to describe incidents that have a likelihood of causing critical incident stress. Battalion - Fire department organizational subdivi...

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 ...

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...

3. ________ isolating mechanisms prevent the fusion of gametes where as _______ isolating mechanisms prevent the proper functioning of the zygote. - Prezygotic, post zygotic • Adaptive radiation - o Existence of groups of closely related species that have recently evolved from a common ancestor by adapting to different parts of the environment. This is common in situations in which species occur in an environment with few other species and many available resources. o Adaptive radiation re...
