Fungi can colonize a dead tree branch and chemically break it down. These fungi are
classified as? - Answer -decomposers
This is the smallest unit of life: - Answer -cell
How do prokaryotes reproduce? - Answer -Binary fission
Who was the first to outline that fossils were evidence of the remnants of past
organisms? - Answer -George Buffon
One species of plant pollinates from July to August, and another species flowers and
pollinates between May and June and as a result do not cross pollinate with each other.
This is an example of: - Answer -temporal isolation
In natural selection, the idea that members of a population differ in inherited traits is
best described as: - Answer -individual variation
Today, cladograms are commonly based on? - Answer -molecular data
The following is a true statement about the characteristics of prokaryotic and eukaryotic
cells: - Answer -prokaryotic cells characterize the make up of bacteria; and eukaryotic
cells make up plants
Who was the first to propose the origin of organic molecules on early earth? - Answer -
Miller and Urey
This is not a type of pre zygotic reproductive barrier: - Answer -hybrid isolation
Which of these occurred most recently according to the geological time scale? - Answer
-origin of most animals
When did prokaryotic life first appear on earth? - Answer -3.5 billion years ago
What is the structure in a bacterial cell that contains the chromosome? - Answer -
nucleoid region
, These are the products of cellular respiration: - Answer -carbon dioxide, water, and ATP
Flagella in bacteria are mainly used for: - Answer -movement
The technique for dating fossils that measures a ration of isotopes is best described as:
- Answer -radiometric dating
Who was the first to link a microorganism to a disease? - Answer -Louis Pasteur
There are two species of fish, one which must live in salt water, and the other in
freshwater. As a result, these two species cannot mate. This is an example of: - Answer
-habitat isolation
What does the similarities in anatomy between the wings of bats and flippers of whales
illustrate? - Answer -homology
Wisdom teeth once served a function in human digestion, but are no longer used.
These are best described as: - Answer -vestigial
Which of these can be classified as a producer? - Answer -plant
This accurately describes both a main tenet and the conclusion of natural selection: -
Answer -overproduction/competition and unequal reproductive success
What is the term for studying the similarities in anatomy in organisms during early
development? - Answer -Comparative embryology
In a population of flowers, the allele for purple flower color is P, and the allele for white
flower color is p. The frequency of P = .1 and the frequency of p = .9. In the next
generation, what is the frequency of the PP genotype with random mating? - Answer
-.01
The term that best describes all the alleles for flower color in a certain species of pea
plant in a population at a certain time is: - Answer -gene pool
What is the outermost layer of a bacterial cell? - Answer -cell wall
What is the broadest level of classification in taxonomy? - Answer -Domain
The Isthmus of Panama is a bridge of land separating the Caribbean Sea and the
Pacific Ocean. On each side of the isthmus, there is a different species of snapping
shrimp that descended from a common ancestor present before the formation of the
isthmus. This is an example of: - Answer -allopatric speciation
This is the correct sequence in the organization of levels of life within a biosphere from
the largest to smallest scale: - Answer -ecosystem, community, population, organism
