How Do We Organize Life?

Based on the characteristics, which would match with the domain bacteria?

• single celled, nucleus, large vacuole

• single celled, no nucleus, cell wall

• single cell, nucleus

• multi-celled, nucleus

What do these two kingdoms have in common?

• Unicellular

• Autotrophic

• Nucleus

• Heterotrophic

What domain has membrane bound organelles like a nucleus?

• Archaea

• Protista

• Bacteria

• Eukarya

Students were divided into groups, to create a tool in different ways. The groups that taught with verbal teaching were 4 times success as the groups that taught with hand gestures. Why is this possible?

• The use of hand gestures, allowed the groups to share more information clearly

• The use of language, allowed the groups to share more information clearly

• The use of bipedal movement, allowed the groups to use their hands more

• The size of their brain cavity, allowed the groups to speak more clearly

The Florida Panther was once considered to be a subspecies of cougars and given a special trinomial taxonomy of Puma concolor coryi. Trinomial nomenclature is a type of taxonomic classification that includes subspecies as a third part of the name in order to distinguish two species that are very closely related. Current scientists, however, have studied the Florida Panther and removed the subspecies classification to only Puma concolor. Which of the following would most likely explain why the classification of the Florida Panther changed?

• New genetic evidence suggests a much closer relationship between the Florida Panther and other cougars.

• Trinomial naming conventions are no longer used by scientists because only the genus and species are important in taxonomy

• Shared features between the Florida Panther and other cougars were also found in newly discovered organisms in the world

• Advanced technologies have shown a large difference in cell structure between the Florida Panther and other cougars.

Students had to classify this organism under a microscope. Which statement supports the appropriate kingdom?

• Kingdom bacteria, because it has a nucleus

• Kingdom archaea, because it has a nucleus

• Kingdom plantae, because it has a cell wall

• Kingdom animalia, because it has a cell wall

Baboons are 97.2% similar to humans, Gorillas are 62.5% similar to humans and chimpanzees are 99.6% similar to humans. Where would baboons be placed on the cladogram?

• Between the chimpanzee and the bonobo

• Between the chimpanzee and the gorilla

• Between the human and bonobo

• Between the gibbon and the orangutan

What happened to the classification system due to advances in technology?

• Advances in DNA sequencing eliminated the original kingdoms

• Advances in DNA sequencing modified our classifications to be more specific and created six kingdoms

• Advances in the microscope allowed the kingdom animalia to be created

• Advances in the microscope allowed the 6 kingdoms to change to 3 kingdoms

What is the best inference drawn from the skulls

• Early hominids had larger brains and had more bipedal movement

• Early hominids had smaller brains that allowed them to create tools

• Early hominids with small jaws passed on those genes more frequently than those with larger jaws

• Early hominids were the top predator and have no evolutionary changes

Which two animals are closely related?

• birds and turtles

• crocodiles and birds

• lizards and mammals

• mammals and crocodiles
