To conduct a phylogenetic analysis, an outgroup is needed in order to: all of these choices are correct. determine which charact
er states are ancestral and which are derived. decide which molecular data to use. determine which characteristics to include in our analysis. decide which characters are analogous and which are homologous.
<span>Determine which character states are ancestral and which are derived. This is an external group that is used to make a phylogenetic analysis that is the set of evolutionary of species and gender, showing their origin and origin. Applied as a method of analysis and reconstruction of information on species classifications. For this it is necessary to determine the ancestral state and its derivatives.</span>
A dam that could allow fish to still pass through is a fishway/fish pass its a "fish ladder" that is structured on or around artificial or natural barriers to allow for fishes natural migration and the movement for potamodromous species.
<em>It is type of phosphorylation in which ATP is directly formed by combing ADP with Pi.</em> <em>It occurs in Glycolysis and Kreb cycle. </em><em>1 3 BisPhosphoglycerate</em><em> is substrate in Glycolysis and </em><em>Succinyl CoA</em><em> acts as substratte in Kreb cycle.</em>
