1. Hawaiian honeycreepers are a group of birds with similar body shape and size. However, they vary greatly in color and beak shape. Each species occupies its own niche and is adapted to the foods available in its niche. The evolution from a common ancestor to a variety of species is an example of _____.
divergent evolution
cross-pollination
vegetative propagation
convergent evolution
2. _____ selection favors one extreme form of a trait in a population.
Directional
Stabilizing
Disruptive
Natural
3. Which answer BEST shows an animal’s adaptation to the tropical rain forest?
camouflage in a tree frog
the long neck of a giraffe
an elephant’s long trunk
migration of birds in winter
4. Upon close examination of the skeleton of an adult python, a pelvic girdle and leg bones can be observed. These features are an example of _____.
artificial selection
homologous structures
vestigial structures
comparative embryology
5. Which of the following is not a factor that causes changes in the allelic frequencies of individuals in a population?
stabilizing selection
directional selection
random selection
disruptive selection

I just need these two questions that I can’t find anywhere.
DOWN
1. Principle proposed by Darwin that suggests that ALL species- living and extinct- were derived from a common ancestor (2 words)
5. Principle proposed by Darwin that suggests that species look different than their ancestors as they adapt to live in different habitats and establish different niches (3 words)

1. Organisms with overlapping niches probably have which type of relationship?
a. commensal
b. competitive
c. mutualistic
d. parasitic
2. Analyze each of the sequences in the primary succession of species colonizing a newly formed volcanic island and select the option in the correct order.
*** is it: bare rock, lichens, small annual plants, perennial herbs and grasses, shade tolerant tree?!
if its not that order…plz give me the right order….thnxx!!
3. How does an enzyme influence a biological reaction?
a. It increases the net energy difference between reactants and products.
b. It decreases the activation energy necessary to initiate the chemical change.
c. It increases the kinetic energy of reactants, thereby increasing their tendency to collide.
d. It decreases the kinetic energy of reactants, enabling them to undergo chemical change more easily.
4. A student set up four test tubes containing starch solution in which to perform starch digestion. Supplies included amylase (enzyme that digests starch) and an incubator. In which tube listed starch digestion proceed most quickly?
a. Tube 1: No amylase, room temperature (25*C)
b. Tube 2: No amylase, body temperature (37*C)
c. Tube 3: Amylase present, room temperature (25*C)
d. Tube 4: Amylase present, body temperature (37*C)
5. What occurs during the process of meiosis in humans that cans lead to a child which the conditions of Down Syndrome?
a. production of a duplicate chromosome set
b. production of gametes which are diploid
c. production of gametes with one duplicate chromosomes
d. production of gametes of gametes with one duplicate sex chromosome.
6. Which of the following is the explanation of why bird wings and reptile forelegs are evidence of evolution?
a. Similar functions point to a common ancestor.
b Analogous structures indicate a common ancestor.
c. Vestigial structures point to a common ancestor.
d. Homologous structures point to a common ancestor.
thnx so much guys…nd plz no comments that does not relate to this ok! <3

1. Hawaiian honey-keepers are a group of birds with similar body shape and size. However, they very greatly in color an beak shape. each species occupies its own niche and is adapted to food available in its niche. The evolution from a common ancestor to a variety of species is an example of:
a. divergent evolution
b. convergent evolution
c. artificial selection
d. inbreeding
2. The flying squirrel of North America closely resembles the flying phalanger of Australia. they are similar is size and have long, bushy tails and skin folds that allow them to glide through the air. The squirrel is a placental mammal while the phalanger is pouched mammal. Their resemblances, even though genetically and geographically separated by huge distances, can best be explained by:
a. divergent evolution
b. convergent evolution
c. artificial selection
d. inbreeding
