OSMT Exam Questions with verified Solutions 100% Solved 2024 Why doesn't phylogenetic systematics have a fixed number of hierarchical categories like Linnaean systematics? - answerEach branching point is a hierarchical level in the nested structure of phylogenetic systematics. The number of branching points—and therefore the number of possible hierarchical levels—varies substantially from one lineage to another. What aspect of evolution does phylogenetic systematics represent more cle...

"Salting out" - certain ions become too concentrated in soils and draw water out of roots by osmosis, causing plant death 2 types of lateral meristems: - Cork cambium vascular cambium 2 ways to increase allele diversity/allele frequency distribution: - 1.) gene flow 2.) mutation 3 Chordate Subphyla - Urochordata, Cephalochordata, and Vertebrata 3 criteria for designating species: Boys Make Pasta - biological, morphological, phylogenetic 4 key characteristics of chordates - 1.) notochor...

Hypothesis vs Theory - hypothesis is and educated guess while a theory is concept that is well supported by observation, experiments, and data. Hardy-Weinberg - No migration, choice of mates random, mutation does not occur, no selection pressure Adaptive radiation - a population colonizes a new habitat and go through natural selection, adapt and become new species (finches). allopatric - isolated population become new species. (porkfish landbridge) Alveolata - Ciliates and dinoflagellates...
