What is a limitation of using morphology to build phylogenies?

Traits that arise independently due to convergent evolution are called:

The root of a phylogenetic tree indicates:

Which two parameters are priorities for the nurse to monitor during treatment? 

 Sister species are:

Which taxonomic level is the most specific?

Directions:Match each condition with its most characteristic finding or management priority.

A newborn develops coughing, choking, and cyanosis during feedings. The nurse notes excessive drooling and is unable to pass a nasogastric tube into the stomach.   Question: These findings are most consistent with [answer1], which places the infant at risk for [answer2] during feedings and requires the infant to be kept [answer3] until surgical repair.

Healthy ecosystems are resilient to normal, natural disturbances, which can take on many forms: windstorms, fire, floods, drought, lightning, and immigration of new species. 

Aquatic life zones are differentiated by factors such as depth, ______, and oxygen concentrations.
