Question

during blood clotting, a broken blood vessel triggers a cascade of factors that collectively reduce blood loss. in this example, the clotting factors are functioning as part of a positive feedback loop. osmoregulation. a negative feedback loop. thermoregulation.

Explanation:

Blood clotting is an example of a positive feedback loop. In a positive feedback loop, the response reinforces the stimulus. Here, the broken blood vessel (stimulus) leads to the activation of clotting factors. As clotting occurs, more clotting factors are activated (the response reinforces the initial stimulus) until the clot is formed and bleeding stops.

• Osmoregulation is the regulation of osmotic pressure in the body to maintain water - balance.
• In a negative feedback loop, the response counteracts the stimulus (e.g., body temperature regulation).
• Thermoregulation is the process of maintaining body temperature.

Answer:

a positive feedback loop.
