In which of the following examples would sepeciation most likely occur? A) Two populations of oak trees begin releasing pollen at different times of the year, one in the spring and the other in the fall B) Unseasonably warm temperatures cause an unusual low pressure zone over the Caribbean leading to a hurricane that eradicates a population of parrots on the island of Saba C) The Fukushima nuclear power plant fails and leaks radioactive water into the ocean causing sterility among an entire p...

NRES 101 Midterm Exam Questions 2024. T/F: Species diversity increases as you approach the equator - correct answer True What are possible reasons why more species occur near the equator - correct answer - More time without geological disruptions (e.g., glaciers) - More niches - Climatic stability - Greater biological productivity What is speciation - correct answer The formation of two species from one ancestral species What factors lead to speciation - correct answer - natural sel...

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? - ...

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...
