Protist Cells Practice Problems

5 problems

1PRACTICE PROBLEM

______is a shared and derived character that is common between an ancestor and its descendants.

2PRACTICE PROBLEM

Which one of the following is not correctly matched with respect to locomotion in different protists?

3PRACTICE PROBLEM

Protists are considered __________ as they include some but not all descendants of their most recent common ancestor.

4PRACTICE PROBLEM

Given below is a phylogenetic tree of all organisms that evolve from a common ancestor.

Which statement correctly describes this phylogenetic tree?

5PRACTICE PROBLEM

The figure below shows a phylogenetic tree.

Based on the above phylogenetic tree, what is the true order of difficulty to develop drugs to combat human pathogens that are prokaryotes, protists, animals, or fungi? (You do not need to consider the evolution of drug resistance by the pathogen.
