Unit 2: Evolution - SBI3U Exam Prep Question and answers graded A+
Extinct - (answer)a species that has completely disappeared from Earth
Adaptation - (answer)a structure, behaviours, or physiological process that helps an organism survive
and reproduce in a particular environment
Mimicry - (answer)a structural adaptation in which a harmless species resemble a harmful species in
coloration or structure
Variation - (answer)differences between individuals, which may be structural, functional, or
physiological (7.1)
Mutation - (answer)a permanent change in the genetic material of an organism.
effect: changes allele frequencies
Selective Advantage - (answer)a genetic advantage that improves an organism's chance of survival,
usually in a changing environment
Paleontology - (answer)the study of ancient life through the examination of fossils (8.1)
Catastrophism - (answer)catastrophes (floods, diseases and droughts) destroy species in a particular
region allowing species from regions nearby to repopulate that area (8.1)
Natural Selection - (answer)The idea that organisms that are the most fit will live to reproduce offspring
that are fit to continue survival of the species
, Unit 2: Evolution - SBI3U Exam Prep Question and answers graded A+
effect: over many generations, frequencies of alleles of many different genes may change, resulting in
significant changes in the characteristics of a population
Evolution - (answer)the process of genetic change in a population over time due to interaction with
biotic and abiotic environmental factors (8.1)
Survival of the fittest - (answer)a phrase coined by John Spencer, expressing the idea that in the struggle
for survival, the reproductively fittest organisms win because they are better adapted to their
environment (8.1)
Embryology - (answer)the study of early, pre-birth stage of development (3.1)
Selective Pressure - (answer)environmental conditions that select for certain characteristics of
individuals and select against other characteristics (7.2)
Fitness - (answer)the relative contribution an individual makes to the gene pool of the next generation
by producing offspring that will survive long enough to reproduce (7.2)
Artificial Selection - (answer)selective pressure exerted by humans on populations in order to improve
or modify particular desirable traits (7.2)
Biotechnology - (answer)the use of technology and organisms to produce useful products
Monoculture - (answer)planting several of the same varieties of a species over large areas of land
Fossil Record - (answer)the remains and traces of past life that are found in sedimentary rock; it reveals
the history of life on Earth and the kinds of organisms that were alive in the past (8.2)
