The cell would be prevented from entering mitosis and the cell would stop dividing. Which diagram best represents the scenario in which lactose is available to the cell and glucose is absent? Answer is C Based on the data in Figure 1, the concentration of iron in the control diet used in the investigation is most likely within which of the following ranges? B. 35-40 mg/kg Which of the following conclusions about dietary iron and ferritin synthesis is best supported by the data in Figure 1? C. C. Maximum activation of ferritin synthesis occurs at dietary iron concentration of 75 mg/kg or greater. Based on the model of ferritin synthesis presented in Figure 2, which of the following best describes the mechanism whereby iron most likely regulates ferritin production? C. Translation occurs under high intracellular iron concentration when the IRP- iron complex dissociates from ferritin mRNA, permitting ribosomes access to the ferritin coding region. Based on the model of ferritin synthesis presented in Figure 2, which of the following describes the role of feedback on the control of intracellular iron levels? D. An increase in iron levels activates synthesis of ferritin proteins. Ferritin in turn binds iron, thereby decreasing both free levels and ferritin synthesis. Acontines controlled similar to ferritan? Answer is B( Acotinas protein increase) By which of the following mechanisms does infection by a retrovirus such as
HTLV-1 most likely cause long-lasting genetic change to host cells? C. The RNA viral genome is reverse transcribed into DNA that integrates into the host genome.

Calcitonin levels will rise, thus promoting the deposit of calcium into bones. Which the following best explains how treatment with a drug that stimulates the production insulin receptor on target
cells will affect the insulin signaling pathway in an individual with type 1 diabetes? A. The drug will have little or no effect on the signaling pathway because the receptors will not be activated in the absence of insulin.
