• changes in the Latin language

• extinction of some organisms

• advancements in lab equipment used to study organisms

• inclusion of abiotic factors in categorizing organisms

Multiple Choice

Multiple Choice

What is a cladogram and what does it represent?

• A type of graph showing population growth

• A branching diagram showing relationships among species

• A chart for classifying animals

• A method for measuring biodiversity

Multiple Choice

• They diverged from a common ancestor more recently

• They have no relation

• They are the same species

Multiple Choice

Students examine images of a certain species of bat commonly found in Texas. Using the bat dichotomous Key, they conclude that the bat species is a Mexican free-tailed bat due to its large, round ears.

• Solitary with a wingspan greater than 35cm

• Solitary with a wingspan less than 35cm

• Colonial with a wingspan greated than 35cm

• Colonial with a wingspan less than 35cm
