7A Which numbered location on the phylogenetic tree identifies characteristics shared by Species B, C, and D?
Location 1
Location 2
Location 3
Location 4
7B Two scientists studied patterns of evolution in the fossil record. Many species they analyzed showed periods of slow changes interrupted by a period of rapid change. This pattern of periods of slow change interrupted by periods of rapid change with few, if any transitional fossils, best describes the theory of —
natural selection
genetic drift
punctuated equilibrium
gene flow
7D 1 Blue flying fish live in the upper layers of the ocean. Blue flying fish have enlarged pectoral fins that enable them to glide for 400 meters above the ocean surface and appear to fly. Which statement best describes how natural selection led to enlarged pectoral fins in blue flying fish?
Fish were able to glide out of the ocean and into other bodies of water to mate with other species.
Fish were able to live both on land and in the water as a result of their larger pectoral fins.
Fish with enlarged pectoral fins were able to glide out of the ocean to escape predators, increasing their fitness.
Fish changed their DNA to express enlarged pectoral fins, changing the allele frequency of the population.
7E Green anoles are lizards that can change their skin color rapidly in response to various stimuli. This adaptation is the result of —
selective breeding of lizards by humans
beneficial traits passed from parents to offspring
geographic isolation that prevented genetic mutation
environmental pollutants that changed their genotype
7E Most animals avoid eating monarch butterflies due to their bad taste. Viceroy butterflies look very similar to the monarchs. Which of these best explains how the viceroy butterfly benefits from looking like the monarch butterfly?
Viceroy butterflies are able to reproduce with the monarch butterflies.
Viceroy butterflies are able to deter predators in the same way as the monarch butterflies.
Viceroy butterflies are able to follow the migratory patterns of the monarch butterflies.
Viceroy butterflies are able to find additional sources of food used by the monarch butterflies.
7F Cross-pollination of flowers from different populations of the same species will most likely result in —
gene flow as new alleles are introduced
evolution of a different species as alleles mix
hybrid sterility as gametes from different individuals are incompatible
a decrease of genetic variation among individuals
8A Why is it important to assign each organism a scientific name?
Each scientific name applies to only one species, making it universally identifiable to scientists.
Each scientific name allows scientists to better study the behavior of an organism.
The scientific name allows scientists to develop common names for organisms.
The scientific name describes how an individual looks relative to others of the same genus.
8B Which mollusk moves by jet propulsion and does not have an external shell?
Squid
Slug
Nautilus
Snail
8B Based on this table, which explanation best describes why elk and fallow deer are classified in the same genus?
They are both in family Cervidae and share a more recent common ancestor
They mate and produce fertile offspring.
They live in similar habitats.
They are both in kingdom Animalia and have similar diets.
8C Which characteristic do all organisms in Kingdoms Animalia, Protista, and Fungi have in common?
They are prokaryotic.
They are eukaryotic.
They are unicellular.
They are multicellular.
7A Based on the cladogram, the ancestral species most likely had —
a vertebral column
a vertebral column and hair
sharp teeth and retractable claws
the ability to purr
7A Based on the cladogram, which set of bat species is the least related?
Ptenochirus minor and Megaerops niphanae
Dyacopterus spadiceus and Otopteropus cartilagonodus
Haplonycteris fischeri and Ptenochirus jagori
Cynopterus sphinx and Chironax melanocephalus
7E The Mexican long-nosed bat roosts in Big Bend National Park in West Texas. The bat feeds on nectar and pollen and hovers while it feeds. Additionally, its tongue can extend up to eight centimeters. The features of Mexican long-nosed bats are evidence of natural selection because the features are adaptations that —
lead to an increase in predation by other species of animals
show that most DNA mutations are necessary and advantageous but do not increase survival or reproductive success
help individuals outcompete other individuals for food resources to increase survival and reproductive success
are the result of intentional breeding
8B Based on the information provided, which two species are most closely related?
Northern cricket frog and bullfrog
Northern leopard frog and green treefrog
Northern cricket frog and green treefrog
Northern leopard frog and bullfrog
8B Based on the dichotomous key, in addition to the shape of the bat’s ears, which other set of features should the students look for to confirm the identity of the bat?
Solitary with a wingspan greater than 35 cm
Solitary with a wingspan less than 35 cm
Colonial with a wingspan greater than 35 cm
Colonial with a wingspan less than 35 cm
