POB Exam 3 UARK Shadwick 2025/2026
Exam Questions and Answers | 100%
Solved
Biological Evolution - 🧠 ANSWER ✔✔organisms change over time
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 - 🧠 ANSWER ✔✔movement of alleles between populations;
mixes genetic diversity in a populations; makes two pools or more similar
populations similar
Random Mating - 🧠 ANSWER ✔✔individuals do not choose mates, never
observed in natural population
Natural Selection - 🧠 ANSWER ✔✔heritable variation, over-reproduction
causes competition and differ in reproductive success and fitness,
Adaptation
