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.

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? - ...

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...
