Honors Biology Evolution Questions and Answers Graded A+ What is natural selection? Natural selection is the process where organisms with traits best suited to their environment are more likely to survive and reproduce. How do mutations contribute to evolution? Mutations introduce new genetic variations, which can lead to new traits that may be advantageous in a changing environment. What is the significance of fossil records in understanding evolution? Fossil records pro...

Acute - Correct Sharp or severe having a rapid onset and short duration. All-Hazard Concept - Correct 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 - Correct Term used in National Fire Protection Association (NFPA) standards to describe incidents that have a likelihood of causing critical incident stress. Battalion - Correct Fire dep...

Micro-evolution - Answer-- a change in an evolution's gene pool over a succession of generations - changes in allele frequencies within populations - often associated with adaptation - can be measured from one generation to the next Macro-evolution - Answer-- major changes in the history of life - origin of new species - generates biological diversity Species - Answer-A population or group of populations whose members have the potential to interbreed with one another in nature to produc...

sci 225 biological species concept - correct answer can reproduce fertile offspring in nature morphological species concept - correct answer species determined by body shape/other structural features phylogenetic species concept - correct answer smallest group of individuals that share common ancestor biogeography - correct answer study of geographic distribution of species over geological time evolution - correct answer change in frequency of alleles speciation - correct answer ...

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...

Which of the following is a postzygotic isolating mechanism? : Hybrid sterillity The courtship rituals performed by some male birds to attract females of the same species are an example of ___ isolation. : Behavioral Speciation due to geographic barriers separating populations is called ___ speciation. : Allopatric All of the following factors have been implicated in mass extinctions, except: 2 | P a g e A. Continental Drift B. Punctuated Equilibrium C. Meteorite Impact D. Loss of H...

species - evolutionarily independent population or group of populations synapomorphy - a trait that is found in certain groups of organisms and their common ancestor, but is missing in more distant ancestors; identifies monophyletic groups; homologous traits that can be identified at the genetic, developmental, or structural level biological species concept - reproductive isolation between populations (they don't breed and don't produce viable, fertile offspring) - reproductive isolation...

Honors Biology – Evolution Questions and Answers Graded A+ What is the significance of genetic drift in small populations? Genetic drift causes random changes in allele frequencies, which can significantly impact small populations. How does the concept of speciation relate to evolution? Speciation is the process by which new species arise from existing ones, contributing to evolutionary diversity. What role does sexual selection play in evolution? Sexual selection favors tr...

What is micro-evolution? - correct answer 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? - correct answer Major changes in the history of life, origin of new species, generates biological diversity "big changes" What is a species? - correct answer a group of populations whose members have the potential to interbreed with one another in nature to produce fertil...
