Answers

1
What distinguishes animal heterotrophy from fungal is that animals derive their nutrition by
preying on animals.
using enzymes to digest their food
ingesting it
consuming living, rather than dead, prey.
2
Which of these should decline in hybrid zones where reinforcement is occurring?
the genetic distinctness of two gene pools
mutation rate
gene flow between distinct gene pools
speciation
3
Which of the following pairs are the best examples of homologous structures?
porcupine quill and cactus spine
bat forelimb and bird wing
bat wing and human hand
owl wing and hornet wing
4
Which of these is the smallest unit that natural selection can change?
an individual's genotype
a population's gene frequency
an individual's genome
an individual's phenotype
5
Natural selection is based on all of the following except
individuals who survive longer leave more offspring
individuals adapt to their environments and, thereby, evolve
best adapted individuals tend to leave the most offspring
pops produce more individuals than the envn. can support
6
Which definition of evolution would have been most foreign to Darwin during his lifetime?
gradual change of a pop's heritable traits over generations
change in gene frequency in gene pools
pops becoming adapted to their environments over generations
descent with modification
7
Which of the following statements is correct about gram-negative bacteria?
5heir cell walls are composed primarily of peptidoglycan
They often possess an outer membrane with toxic LPS
they have more DNA vs cells of taxonomically higher organism
penicillins are the best antibiotics to use against them
8
The best classification system is that which most closely
reflects the basic separation of prokaryotes from eukaryotes
conforms to traditional, Linnaean taxonomic practices
unites organisms that possess similar morphologies.
reflects evolutionary history.
9
Why might a point mutation in DNA make a difference in the level of protein's activity?
It might exchange one serine codon for a diff. serine codon
It might substitute an amino acid in the active site
It might result in a chromosomal translocation
It might exchange one stop codon for another stop codon
10
Which eukaryotic kingdom is polyphyletic, and therefore unacceptable, based on cladistics?
Protista
Monera
Animalia
Plantae
11
Which of the following is (are) unique to animals?
nervous conduction and muscular movement
heterotrophy
cells that have mitochondria
the structural carbohydrate, chitin
