BSC 1005 UPDATED EXAMS EVALUATION
QUESTIONS AND ANSWERS SURE A+
✔✔Biophilia - ✔✔Attraction to the elements of the natural world (humans enjoy going to
zoos and watching nature programs)
✔✔Comparative method - ✔✔When biologists compare different forms of life to reveal
the relationship between form and function
✔✔Genomics - ✔✔The study of the molecular structure of many genes at the same
time
✔✔Genome - ✔✔The entire set of genetic material in a cell
✔✔Mass extinction events - ✔✔Period in which biodiversity dramatically declined
*The world has seen 5 over the last 450 million years
✔✔Last extinction 65 million years ago resulted in.. - ✔✔The extinction of dinosaurs
✔✔How was all the diversity on Earth originated after life originated? - ✔✔Evolution
✔✔Population - ✔✔All the organisms of one species, in one area (That are capable of
interbreeding and vary in their characteristics)
, ✔✔Mean - ✔✔Typical value of population
✔✔Standard deviation - ✔✔Measure of variation (Average distance from the mean)
✔✔The wider the bell curve.. - ✔✔the more range/deviation
✔✔Typologically - ✔✔When people assign things to categories and expect them to fit in
those categories (A cat is a cat. A dog is a dog)
✔✔Natural Selection - ✔✔Occurs through:
Differential reproduction (Not all individuals can survive and reproduce)
Heredity (Parents pass characteristics on to offspring)
Variation (Some characteristics make individuals more likely to survive and reproduce)
✔✔Variation - ✔✔Individuals with different traits/characteristics
✔✔Differential reproduction - ✔✔Some individuals within a species do not reproduce,
while others do
✔✔Heredity - ✔✔The ability of parents to pass characteristics on to offspring
✔✔Directional Selection - ✔✔Individuals at one end are successful. Individuals at the
other end are unsuccessful.
✔✔Stabilizing selection - ✔✔Select individuals closer to the mean (more likely to
survive and reproduce)
✔✔Disruptive selection - ✔✔Individuals close to the population mean do the worst,
those at the extreme do the best. Population diverges into two different groups.
✔✔What were Charles Darwin two main ideas? - ✔✔Natural Selection and Descent
with modification
*Individuals came from a common ancestor but may adapt to different traits
✔✔Darwin's observations on the Galapagos Islands convinced him that.. - ✔✔many
animals found there evolved from mainland forms
✔✔Natural selection does not act on characteristics that .. - ✔✔don't occur in nature or
are dead
✔✔Alfred Wallace - ✔✔Independently came up with the idea of natural selection
