Question 1 0.125 out of 0.125 points The cellular response indicative of injury because of faulty metabolism is Selected Answer: d. intracellular accumulations. Correct Answer: d. intracellular accumulations. Response Feedback: Intracellular accumulations result from faulty metabolism of lipids, carbohydrates, glycogen, and proteins. Hydropic swelling results from malfunction of the sodium-potassium pump. Lactate production results from anaerobic glycolytic pathway. Metaplasia occurs from persistent cell injury. Question 2 0.125 out of 0.125 points Necrotic death of brain tissue usually produces _____ necrosis. Selected Answer: c. liquefacti ve Correct Answer: c. liquefacti ve Response Feedback: Liquefactive necrosis is produced when brain tissue dies, as it is rich in enzymes and has little connective tissue. Coagulative necrosis occurs from ischemic injury in any tissue. Caseous necrosis occurs in lung tissue damaged by tuberculosis. Fat necrosis occurs in adipose (fat) tissue. Question 3 0.125 out of 0.125 points Breast cancer in women who have the breast cancer gene Selected Answer: c. occurs at an earlier age. Correct Answer: c. occurs at an earlier age. Response The age of onset of inherited breast cancer is earlier than the onset of

Feedback: non-inherited forms and the prevalence of bilateral breast cancer is higher. Breast cancer in women who have the breast cancer gene is less common (only 5% to 10% of all cases) than non-inherited breast cancer and is more likely to be bilateral. Response to treatment is not affected by whether the cancer gene is present. Question 4 0.125 out of 0.125 points Allostasis is best defined as Selected Answer: d. the overall process of adaptive change necessary to maintain survival and well-being. Correct Answer: d. the overall process of adaptive change necessary to maintain survival and well-being. Response Feedback: Allostasis refers to the overall process of adaptive change necessary to maintain survival and well-being. Question 5 0.125 out of 0.125 points In general, a cancer cell that is more tissue-specific differentiated is more likely to be aggressive. Selected Answer: a. Fal se Correct Answer: a. Fal se Response Feedback: The degree of tissue-specific differentiation predicts malignant potential. A lack of differentiated features in a cancer cell is called anaplasia, and a greater degree of anaplasia is correlated with a more aggressively malignant tumor. Question 6 0.125 out of 0.125 points Metaplasia is Selected Answer: b. the replacement of one differentiated cell type with another. Correct Answer: b. the replacement of one differentiated cell type

with another. Response Feedback: Metaplasia is the replacement of one differentiated cell type with another secondary to persistent damage. Dysplasia transforms cells to preneoplastic lesions, which may become malignant. Metaplasia is reversible when the damage is stopped. Disorganization of cells into various sizes, shapes, and arrangements occurs in dysplasia.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
