Answer:
(1) competent cell preparation, (2) transformation of cells, (3) cell recovery, and (4) cell plating
Explanation:
Exocytosis is the correct answer. Zymogens like pepsinogen are leaving, not entering the cell, so it's not exocytosis. They are too large for channel protein transport or simple diffusion. They are "shipped" outside the cell via vesicular transport into the gastric lumen, where catabolism of proteins can begin.
Generalizability is the process by which conclusions are drawn from a group of research results to create a scientific theory which is statistically probable. The conclusions drawn for example, from a study of a specific group in society can then be applied to a larger population to make a general conclusion. This can have issues based on the variables such as age, gender, location, which may provide less scope for the results; therefore if the study is not taken of a large enough cross-section of results, then it makes the generalizability limited.
