Bio 100 Exam 3 (Jaeger UNLV) Questions and Answers 100% Pass **Explain biotic potential.** Most populations can produce more offspring than the environment can support. **Define heritable.** Traits that can be passed on to the next generation. **Describe the concept of evolution of acquired characters.** Over time, an organism can accumulate enough changes that one species may diverge into two, tracing back through ancestral species. **List the five agents of evolution.** Nat...

Monophyletic Group - Answer-includes all the descendants of a common ancestor, and its considered a natural grouping of organisms based on a shared ancestry. Paraphyletic Group - Answer-some (not all) of descendants of a common ancestor Polyphyletic Group - Answer-organisms from distinct lineages based on shared characters, but no common ancestor Homologies - Answer-similarities based on shared ancestry Analogies - Answer-similarities based on independent adaptations Synapomorphies - Answ...

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 ...
