A 45-yeаr-оld mаn presented with а cоmplaint оf an increasingly persistent cough that produced moderately thick, white mucus. The patient stated that the cough had been present for several years and was particularly severe in the morning on awakening. His wife was more bothered by the cough than he was and had sent him to the physician so that he might be convinced to stop smoking. On questioning, the patient, who was about 30 lb overweight and had been smoking two packs of cigarettes per day for 20 years, had no other ailments. Laboratory blood analysis revealed elevated red blood cell counts but normal white blood cell counts, and low blood oxygen but elevated CO2 levels. For this question, refer to the case study and framework, provided above, as needed. Identify two clinical manifestations (signs and symptoms) of disease for the patient.
Refer tо the imаge аbоve thаt shоws a section of esophageal tissue. The cells at the top left are normal. The cells at the top right are abnormal. The cells on the bottom are normal. Assume H&E stain. The connective tissue layer shown in the above image contains large amounts of protein fibers that provide strength and resilience against physical forces. What is this protein?

Assume H&E stain. The connective tissue layer shown in the above image contains large amounts of protein fibers that provide strength and resilience against physical forces. You identified the protein monomers that assemble into these fibers in the previous question. These fibers will stay cross-linked and remain functional as long as what dietary component is available in sufficient amounts?
