Biology ABCTE Certification Test Part 1
Exam
genetic drift - correct answer-The following phenomena affect Hardy-Weinberg
equilibrium. Which one is associated with small populations and chance changes in
allele frequency?
allantois - correct answer-Which embryonic membrane develops into the umbilical cord
in placental mammals?
separation of homologous chromosomes during meiosis - correct answer-Mendel
observed that pea color was a characteristic passed independently of flower color. What
causes this phenomenon?
the gravitational force of Mars - correct answer-Which factor influences your weight on
the Mars?
they are the principle component of cell membranes - correct answer-What is the
function of lipids?
use of selective protein channels - correct answer-How does facilitated diffusion differ
from ordinary diffusion across a cell membrane?
bacteriophages can be injected into human cells - correct answer-What conclusive
knowledge did the Hershey-Chase experiments contribute to molecular biology?
parasympathetic - correct answer-What division of the nervous system would stimulate
digestion of food?
number of flower parts - correct answer-Which characteristic would differentiate
between a monocot and a dicot?
noble gases - correct answer-Which periodic table group has the preferred electron
configuration of all atoms?
carbon tends to share electrons in covalent bonds - correct answer-How does the
number of valence electrons in an atom of carbon influence the kinds of bonds it tends
to form?
both are dipoles - correct answer-How does a bar magnet resemble the Earth's
magnetic field?
, blue - correct answer-Which range of the visible light spectrum has the highest energy
per photon?
Experimental methods and conclusions should be repeated and accepted by other
scientists. - correct answer-How can one decide if conclusions reached by a scientist
conducting an experiment are valid?
chromosomes line up at the cell's equator - correct answer-What happens during the
metaphase stage of mitosis?
Antigens activating B lymphocyte proliferation - correct answer-Which is classified as a
specific host defense mechanism?
co-dominance - correct answer-Blood types A, B, O, and AB are examples of what
pattern of inheritance?
polymerase chain reaction - correct answer-What process is used to make many copies
of a particular gene very quickly?
analogous structures - correct answer-Which term describes the relationship between
the wings of a butterfly and the wings of a bat?
heavy snow - correct answer-Which is a density-independent factor limiting population
growth?
sonar - correct answer-What evolutionary innovation of the nervous system allows some
mammals to perceive objects in dark terrestrial environments and other mammals to
perceive objects at very great distances in the ocean depths?
it supports the idea of common ancestry and not direct descent - correct answer-
Scientists studying the molecular genetics of modern humans and extinct Neanderthals
have concluded that modern humans are not descended from Neanderthals and that
the first Cro-Magnons probably did not interbreed with Neanderthals. How does this fit
with evolutionary theory?
because both diploid and haploid forms are multicellular - correct answer-Why are
plants considered to undergo a true alternation of generations?
unstable phosphate bonds - correct answer-What aspect of ATP makes it an excellent
"energy currency" for cells?
increases x 10 - correct answer-If the pH of a solution decreases from 4 to 3, how is the
hydrogen ion concentration affected?
