Ultimate AP Biology Exam Review Questions with Verified Answers Compare and contrast transpiration and translocation. What is the difference between xylem and phloem? Tranpspiration is the loss of water vapor from the surgace of a plant through the stomata. Translocation is the channeling of the sugar through the phloem. Define hypoosmotic, hyperosmotic, and isomotic 1. Has a lower concentration of solutes than its surrounding enviorment 2. Has a higher concentration of solutes than i...

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...

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? - ...

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...

Convergent vs Divergent Evolution - ANSWER -Divergent: one broad class but because of different features they diverge -Convergent: similar features between 2 different classes Punctuated Equilibrium vs Gradualism - ANSWER -Punctuated: concrete & defined phenotypes -Gradualism: phenotypes gradually evolve Speciation - ANSWER Formation of new species 1) Allopatric: separated by geographical barrier (mountain, ocean, river) -Barrier divides species 1 and species 2 2) Parapatric...

Taxonomy - Answer The field of biology that is involved in naming, describing, and classifying organisms, both extinct species and extant species International Code of Zoological Nomenclature (ICZN) - Answer The formal rules used by scientists in naming to promote stability and universality in the scientific names of animals and other organisms. Classification - Answer One branch of taxonomy where various things are identified and grouped together into groups. This orders and rank...

Adaptive Radiation - An evolutionary pattern in which many species evolve from a single ancestral species Allele - An alternative form of a gene. Allele Frequency - Number of times that an allele occurs in a gene pool in comparison to the total number of alleles allopatric speciation - The formation of new species in populations that are geographically isolated from one another. allopolyploidy - a species with multiple sets of chromosomes derived from different species Alpha (origination...

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...

Natural selection - ANSWER Process that determines which individuals will pass on their genes to the next generation Evolution - ANSWER the changes that we see in the genes and characteristics displayed by successive generations of a population Speciation - ANSWER the production of a new species from a previously existing species Allopatric speciation - ANSWER separated by land Sympatric speciation - ANSWER speciation in the same area; exploiting unused resources causes them to becom...
