POB EXAM 1 SHADWICK CERTIFICATION
EVALUATION ACTUAL QUESTIONS AND
ANSWERS FULL SOLUTION VERIFIED
SUCCESS
●● Darwin
Answer: Theory of Natural Selection (short necked giraffes die and
therefore, don't reproduce)
●● Lamarck
Answer: Inheritance of Acquired Characteristics (giraffes stretch their
necks to reach food and then their offspring are born with the longer
neck)
●● Evidence of Evolution
Answer: Fossils, Transitional Forms, Analogous Structures,
Homologous Structures, Vestigial Structures
●● Fossils
Answer: hard body parts, embedded in sedimentary rock, deposited in
Strata
●● Mold
,Answer: air space remains
●● Cast
Answer: Silica fills space
●● Transitional Form
Answer: Whale: reduced hind limbs and pelvic bones
●● Analogous Structure
Answer: evolved separately but have similar functions ex. human and
octopi eyes
●● Homologous Structure
Answer: similar structure but have different functions ex. arm, cat,
whale, bat
●● biochemical evidence of evolution
Answer: DNA, ATP, enzymes are universal
●● Genetic Code evidence of evolution
Answer: RNA to amino acid triplets are universal, many genes are
shared by all organisms
, ●● Microevolution
Answer: change in allele frequency in a population over time
●● who evolves
Answer: populations
●● Hardy Weinberg Equilibrium
Answer: No mutations, No genetic drift, No gene flow, No natural
selection, Random Mating
●● Mutation
Answer: cause allele frequency in a populations, only source of
variation, random events
●● Genetic Drift
Answer: causes allele frequency to fluctuate; greater in smaller
populations
●● Bottleneck Effect
Answer: catastrophe kills large amount of people, loss of genetic
diversity; recessive alleles become more present
●● Gene Flow
