Pre-AP
Biology Pre-AP Example Items are a representative set
of items for the ACP. Teachers may use this set of items along with the test
blueprint as guides to prepare students for the ACP. On the last page, the
correct answer and content SE is listed. The specific part of an SE that an
Example Item measures is not necessarily the only part of the SE that is
assessed on the ACP. None of these Example Items will appear on the ACP.
Teachers may provide feedback with the form available on the Assessment
website: assessment.dallasisd.org.

The production of insulin and glucagons occurs in the pancreatic Islets of Langerhans. How do
insulin and glucagons work together to maintain homeostasis?
A
Glucagons work to lower sugar levels when the body temperature is too high, while insulin
works to increase sugar levels when the body temperature is too low.
B
Insulin works to lower sugar levels when the body temperature is too high, while
glucagons work to increase sugar levels when the body temperature is too low.
C
When blood sugar rises glucagons are released, which stimulates cells to accept glucose.
When blood sugar is low, insulin is secreted, which aids in converting fats and proteins into
glucose.
D
When blood sugar rises insulin is released, which stimulates cells to accept glucose. When
blood sugar is low glucagons are secreted, which aids in converting fats and proteins into
glucose.
On the hemoglobin gene, glutamate is sometimes replaced by valine.
Normal Cells
Mutated Cells
What is the significance of this change?
A
A point mutation causes sickle cell anemia, which results in disfigured red blood cells.
B
A chromosomal mutation causes Klinefelter’s syndrome, which results in reduced fertility.
C
A deletion mutation causes muscular dystrophy, which results in muscle degeneration and
death.
D
A translocation mutation causes chronic myeloid leukemia, which affects blood circulation.
