Exam 14: The History of Life

Use the figure shown below to match the Linnaean classifications with category names for humans. -Hominidae

Correctly match the definition with the correct geologic time period. -further increases in diversity of marine invertebrates and vertebrates; plants and fungi begin to colonize land; mass extinction at end of period; 445-490 mya

Evolutionary tree diagrams representing the relationships between various organisms can be drawn only when those organisms share a

List the four kingdoms within the domain Eukarya and list one characteristic for each of the four kingdoms.

Evolutionary trees are continually revised by scientists as new information becomes available from various sources such as

Information about the decline in animal groups during the first five mass extinctions was expressed as a percentage of animal families that went extinct.Can the graph shown below be used to determine the percentage of animal families lost during the current mass extinction? If so,what is the percentage of animal families that have gone extinct since 1500? If not,why not?

Although it is costly to produce fruit,the large number of fruit-producing plant species attests to its success as an evolutionary adaptation.In what way is fruit production helpful to plants?

According to the classification chart shown below,humans are in the phylum ________.

Use the figure shown below to match the Linnaean classifications with category names for humans. -Homo

Correctly match the definition with the correct geologic time period. -continents near present positions; increased diversity of flowering plants,birds,mammals,and pollinating insects; 2.6-65 mya

Upon examining specimens recovered from the small intestine of a murder victim during the autopsy,clusters of cells are found that are attached to each other by shared cell walls.The outer layers of these cells are covered with a waxy cuticle,and there is evidence of many green organelles inside the more intact cells in the clusters.What type of cells might these be?

The emergence of each new branch on the evolutionary tree represents

The following geologic periods,listed in alphabetical order,are the most recent: Cretaceous,Jurassic,Paleogene/Neogene,Quaternary,and Triassic.Re-order the names of the periods beginning with the most recent.Then,choose one of these geologic time periods and describe the major events during that period.

What criteria best characterize membership in the kingdom Protista?

Correctly match the definition with the correct geologic time period. -flowering plants begin to dominate life on land; mass extinction at end of period,including extinction of the last dinosaurs; 65-145 mya

Match each adaptation with the most specific group in which that adaptation arose. -first plants to produce pollen

The following Linnaean classifications are listed alphabetically: class,family,genus,kingdom,order,phylum,and species.Re-order these classification names beginning with the category that includes the largest number of organisms and ending with the category with the least number.

Use the figure shown below to match the Linnaean classifications with category names for humans. -Animalia

Monotremes,like the duck-billed platypus,are egg-laying mammals covered in hair,have mammary and skin glands,have three ear ossicles,are diphyodont,and possess dentary-squamosal jaw articulation.Marsupials,such as kangaroos and koalas,are pouched mammals that have a vertical tympanic membrane in addition to possessing characteristics observed in monotremes.Eutherians,such as humans,are placental mammals that have a vertical tympanic membrane in addition to possessing characteristics observed in monotremes. What one shared derived trait sets marsupials and eutherians apart from monotremes?

The most recent mass extinction,which occurred during the Cretaceous period,may have been caused by
