## Step 1The problem describes a process where the body responds to an increase in blood pressure by lowering the heart rate and thus, the blood pressure. This is a mechanism of maintaining a stable internal environment in the body, which is a characteristic of homeostasis.## Step 2Active transport is a process that involves the movement of molecules across a cell membrane from an area of lower concentration to an area of higher concentration. This process requires energy and is not related to the regulation of blood pressure.## Step 3Buffering is a process that helps to maintain a stable pH in a solution. It is not related to the regulation of blood pressure.## Step 4Passive transport is a process that involves the movement of molecules across a cell membrane from an area of higher concentration to an area of lower concentration. This process does not require energy and is not related to the regulation of blood pressure.
