Japanese maple and Lodgepole pine
Taiwan beech and Taiwan catkin yew
Lodgepole pine and Taiwan catkin yew
Taiwan beech and Japanese maple
An analysis of DNA sequences can be used to classify organisms. The phylogenetic tree is based on molecular data and represents evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor.
Which statement is best supported by the information in this phylogenetic tree?
Dogs are more genetically similar to sea lions that they are to seals
Weasels are more genetically similar to monkeys than they are to cats
Raccoons are more genetically similar to dogs than they are to weasels
Dogs are more genetically similar to bears than they are to raccoons
The arctic fox, polar bear, and white rabbit all have white fur and live in snow covered climates. The white fur is an example of ___________.
Advantage
Adaptation
Genetic Drift
Extinction
Researchers studying medium ground finches on the island of Daphne Major in the Galapagos Islands collected the data below on the survival rates of finches with different sized beaks over a three-year period that included a drought.
Which statement about the finches in this environment is best supported by the data?
Finches with medium beaks had more mutations than the other finches did
Finches with small beaks reproduce more quickly than finches with large beaks
Finches with large beaks had more genes that the other finches did
Finches with large beaks are more fit for the environment than finches with small beaks are
Which of the following is NOT a component of Natural Selection?
Some organisms can better survive and reproduce
Change in population due to gene frequency
The strongest survive
Inherited variations
Dogs and cats are both animals in the Class Mammalia. Therefore, both dogs and cats are also classified in the same –
Species
Kingdom
Genus
Family
A population of 500 owls decreased to 75 after their home was lost to deforestation, the cutting down of trees for farm land or resources. Which mechanism of evolution led to this population change?
Natural Selection
Gene flow
Mutation
Genetic Drift
Adaptations that result from Natural selection are expected to increase the fitness of an organism. In terms of Natural Selection, which of the following best describes fitness?
Being able to escape from predators
Being amongst the strongest organisms in the population
Being able to survive, find a mate and produce offspring
Being able to survive long enough to reach the adult stage
Which of these pairs of scientific names identifies two different species of the same genus?
Protea compacta and Amoeba proteus
Ceris texensis and Lupinus texensis
Quercus rubra and Acer rubrum
Canis lupus and Canis latrans
All of the characteristics apply to organisms in the Plantae and Fungi Kingdoms, Except -
Have Eukaryotic cells
Are Photosynthetic
Non-motile
Most are multicellular
Part of the DNA sequence from several species is being compared in the chart. Based on the DNA sequences provided the Unknown Species is more closely related to which of the following species?
Species I
Species II
Species III
Species IV
The diagram shows light and dark beetles that live on a tree. Which statement best describes what will happen to the beetle population due to predation?
The population of dark colored beetles will increase
The light and dark colored beetle population will not change
The dark colored beetles will move to a different type of tree
The number of light colored beetles will increase over time
Researchers compared a specific protein across different species. The table shows the number of differences in the protein between the species.
Which conclusion does the data support?
Ladybugs are more closely related to Wolf Spiders that they are to Beetles
Beetles and Wolf Spiders are the most closely relate organisms
Beetles are more closely related to Crickets than they are to Grasshoppers
Crickets are more closely related to Wolf Spiders than Grasshoppers are
A group of scientists has been studying and comparing the genome maps of domestic dogs and wolves. What do these genome maps allow the scientists to determine? (genome is their DNA)
The behavioral patterns of each species
How closely related the two species are
What their primary food sources are
Their patterns of predation
One individual bacterium has developed a new trait that has caused them to be resistant to common medicines used to kill them. Which mechanism of evolution allowed this bacterium to develop resistance?
Mutation
Natural Selection
Gene flow
Genetic Drift
A population of termites initially consists of darkly colored and brightly colored members. After several generations, the termite population consists almost entirely of darkly colored members because the brightly colored termites are easier for a predator to see. This situation is an example of—
The evolution of a new species
Artificial Selection
Extinction
Natural Selection
Cetaceans are Whales and their relatives, the diagram shows some fossils of cetaceans. Which statement provides evidence that Ambulocetus natans is an ancestor of Basilosaurus isis?
Homologous structures occur in each fossil
Both fossils were found in different locations
The youngest fossil is larger than the oldest fossil
Fossil cannot be compared

Insects
Arachnids
Worms
Mollusk
Which statement is NOT true about Eukaryotic cells
They have a nucleus
Eukaryotes have membrane bound organelles
The DNA is free floating inside the cell
Organisms like animals and plants have eukaryotic cells
