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...

Recognize dragonflies as formidable aerial and aquatic predators - correct answer Dragonflies live in water for the first two years of their life.

radiometric dating - general approach used to determine the age of specimens using the rate of decay of radioactive isotopes radiocarbon dating - a chemical analysis used to determine the age of organic materials based on their content of the radioisotope carbon-14 potassium-40 dating - radiometric dating method often used in the assessment of volcanic intrusions in sedimentary layers. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into ar...
