Biology 101 Exam #1 (SDSU Ekdale)
The ability of an individual to survive and reproduce in its environment relative to other
individuals is called its: - -fitness
-The specific study of multicellular and heterotrophic organisms that acquire nutrition
through ingestion is also know as: - -Zoology
-____recognized that heritable traits of an organism were passed from parent to offspring
on "genes" - -Gregor Mendel
-An adaptation is a feature that: - -increases the chance that an individual will reproduce
-Certain species of land snail are found in isolated populations in high elevation habitats
on mountaintops. There are mountain ranges in which different mountaintops will have
different, but very closely related, species of snails. The snails cannot survive if they travel
to lower elevations--thus the snails cannot move to populations on other mountains (i.e.,
the various species are both reproductively and geographically isolated.) Evolutionary
biologists studying these snails have argued that the different species of snail arose
through the process of: - -allopatric speciation
-The physical expression of an organism's genetic constitution is called its: - -phenotype
(visible or expressed characteristics of an organism, influenced by the genotype)
-What does the theory of endosymbiosis explain? - -Evolution of the eukaryotic cell
-Why is taxonomy, or the naming and organizing of organisms, important? - -All of the
above.
-Two different groups of organisms are termed sister taxa if: - -they share common
ancestry with each other more recently than either one does with any other organisms
-A membrane-bound nucleus within the cell is a synapomorphy for the monophyletic
group called - -Eukarya
-Cilia, flagella, and pseudopods are structures found in some unicellular "protists" that: - -
allow the organisms to move
-British geologist Charles Lyell popularized the principle of uniformitarianism, which
states that: - -natural laws of physics and chemistry have remained constant throughout
Earth's history
-A synapomorphy: - -a heritable attribute that is shared between two or more taxa
