QUESTIONS WITH SOLUTIONS GRADED A+
◍ Evidence that habituation is not due to sensory adaptation nor motor
fatigue:.

reflexive machinesSolution: distinguished between Pavlov and
InstrumentalEliminated S and REmphasized that we should only study the
rate of responding that is modified by rewards and punishments
◍ Promoters of genes that are involved in the synthesis of the spore coat are
indicatedby arrows on the representation of a bacterial chromosome at right.
How do you think a bacterium would most efficiently control spore coat
biosynthesis?.
Answer: by using a sporulation-specific alternate sigma factor
◍ Dishabituation.
Answer: If habituation is due to sensory adaptation or motor fatigue, you
would not expect a brief distraction to restore responding but the response
does partially return
◍ Biochemical Mechanisms.
Answer: Neurotransmitter release decreases at the synapse Due to an
, inactivation of Ca2+
◍ Which of the following is NOT a difference between DNA polymerase and
RNA polymerase?.
Answer: The direction in which the template is read
◍ Ranking of partnership creditors compared to private creditors.
Answer: If the partnership creditors will not be paid in full from partnership

◍ More than 20% lymphoblasts in marrow is the correct answer. Acute
lymphoblastic leukemia/lymphomas (ALLs) are neoplasms composed of
immature B (pre-B) or T (pre-T) cells, which are referred to as
lymphoblasts. About 85% are B-ALLs, which typically manifest as
childhood acute leukemias. Physical exam may reveal pallor, ecchymoses,
lymphadenopathy, or hepatosplenomegaly. There may also be evidence of
tissue infiltration such as bone pain, testicular enlargement, and cranial
nerve palsies. A Presence of 20% or more lymphoblasts in the bone marrow
confirms the diagnosis of AL
L. .

limbs. Labs:Hb 11 gm% (N 14 to 18 gm%)Total white cell count: 20,000
