Bio Star Testing Review
A computer model of cellular mitosis can stimulate the aspects of cellular division quite
well. However, microscopic observations of actual cellular mitosis can improve
understanding because actual observations... - answersMay reveal greater unknown
complexities
The cell membrane of a red blood cell will allow water, oxygen, carbon dioxide, and
glucose to pass through. Because other substances are blocked from entering this is
called.. - answerssemi-permeable
There are many different enzymes located in the cytoplasm of a single cell. How is a
specific enzyme able to catalyze a specific reaction? - answersAn enzyme binds to a
specific substrate (reactant) for the reaction catalyzed
Maltose can be broken down into glucose molecules by the enzyme maltase. What
would slow down a reaction rate? - answersdiluting with water
a food chain is shown below
Grass-- Crickets--Field Mice-- Hawks
For the Food chain below what change would have the most severe consequences? -
answersA drastic decrease in rainfall, causing drought
The first stage in photosynthesis in a chloroplast is? - answerslight dependent
The plasma membrane of a cell consists of - answerstwo layers of lipids organized with
the non-polar tails forming the interior of the membrane.
What system is signaling muscle tissues to contract part of? - answersnervous system
What is the greatest danger to a patient who has damage to the skin? -
answersinfections in uncovered tissues
A small population of monkeys lives in a habitat that undergoes no changes for a long
period of time. How will genetic drift probably effect the population? - answersIt will
increase the number of alleles for each trait
In fruit flies, the gene for red eyes(R) is dominant and the gene for pink eyes (r) is
recessive. what are the possible combinations in the offspring of two red eye-
heterozygus (Rr)? - answersRR, Rr, and rr only
In aerobic respiration, the Krebs cycle (citric acid cycle) takes place in -
answersmitochondria
, Which cellular organelle is responsible for packaging the proteins that the cell secretes?
- answersGolgi apparatus
What process only occurs in the reproductive cells of an organism? - answersmeiosis
What is the most helpful organism in preventing Earth from being covered in dead
bodies? - answersFungi and bacteria
Eukaryotic cells are differentiated from prokaryotic cells because eukaryotic cells -
answershave nuclei
Two students were testing the amount of fertilizer that would best promote the growth of
strawberries in a garden. What would be an unavoidable source of experimental error? -
answersvariation in the strawberry plants
Medel hypothesized that reproductive cells only have one factor for each inherited trait.
The hypothesis is supported by the observation that.. - answershaploid cells are
produced by meiosis
A signal that the bladder is full is sent to the central nervous systems by.. -
answerssensory neurons
What illustrates natural selection? - answersAn organism with favorable genetic
variations will tend to survive and breed successfully.
A cell from a heart would probably have a unusually high proportion of -
answersmitochondria
What represents chromosome number during fertilization? - answersn + n= 2n
Based only on sex chromosomes in typical human egg and sperm cells at fertilization,
the probability of producing a female is - answers25%
In certain breeds of dogs, deafness is due
to a recessive allele (d) of a particular gene, and normal hearing is due to its dominant
allele (D). What percentage of the offspring of a normal heterozygous (Dd) dog and a
deaf dog (dd) would be expected to have normal hearing? - answers50%
Mutations within the DNA sequence are - answersnatural processes that create genetic
diversity
Striking the tendon just below the kneecap
