the figure above shows an organelle typically found in eukaryotic cells. Which of the following
best describes the function of the double membrane system of this organelle? - ANSWERS -the
inner membrane has specialized proteins that create a hydrogen ion concentration gradient
between the intermembrane space and the matrix
which of the following best describes an event during step 2 in the simplified model above? -
ANSWERS -noncoding sequences are removed from a newly synthesized RNA molecule
which of the following correctly compares the two processes shown above? - ANSWERS -both
processes increase genetic variation
based on the model, which of the following mutations is most likely to result in a cell that will
generate a cancerous tumor? - ANSWERS -a mutation in the gene encoding G-PIP that results in
a nonfunctional protein
the food web represented above does not include bacteria and fungi. whcih of the following
best describes a consequence of having no bacteria and fungi in the food web? - ANSWERS -
grasses will have no direct access to chemical components recycled from dead organisms
the following DNA sequence is a small part of the coding (nontemplate) strand from the open
reading fram of the B-hemoglobin gene. Given the codon chart listed below, what would be the
effect of a mutation that deletes the G at the beginning of the DNA sequence? - ANSWERS -the
reading frame of the sequence would shift, causeing a change in the amino acid sequence after
that point
, which of the following questions might scientists ask to most reliably determin if there has ever
been life on Mars? - ANSWERS -did Mars have elements present in its atmosphere to support
life?
Cortisol is a hormone produced in response to stress, including starvation, in humans. Which of
the following is most likely an immediate effect of a starvation induced increase in cortisol
secretion? - ANSWERS -increased mobilization of gatty acids from fat cells
which of the following is the most likely consequence of adding ciproflozacin to animal feed? -
ANSWERS -ciprofloxacin resistant strains of C. jejuni will have a selective advantage in the
digestive tracts of livestock, increasing the risk of serious infection in people
the table above shows derived characters for selected organisms. Based on the information in
the table, which of the following cladograms best represents the evolutionary relationships
among the organisms? - ANSWERS -Fish breaks off first
damaged tissue releases chemicals that activate platelets and stimulate the formation of blood
clots. WHich of the following predictions about the activity of platelets best describes a positive
feedback mechanism? - ANSWERS -activated platelets release chemicals that activate more
platelets
based on the results of the experiment, which of the following types of molecules did the
bacteriophages most likely inject into the bacteria cells? - ANSWERS -DNA
which of the following conclusions is best supported by the results of the experiment? -
ANSWERS -neither population grows as large when cultured together as each does when
cultured separately
