Which property enables mammals to maintain a relatively constant body temperature? positive feedback system antagonistic hormones ability to prevent a dynamic equilibrium goosebumps negative feedback system

## Step 1: <br />Understanding the question. The question aims to find out which mechanism helps mammals keep their body temperature fairly consistent.<br /><br />## Step 2: <br />Keeping terms in mind which is related to thermal regulation. The 'negative feedback system' plays a crucial part in the regulation of an organism's internal environment, aiming to stabilize physiological variables such as temperature at beneficial and consistent levels. <br /><br />## Step 3: <br />Considering each option. It is known that 'goosebumps' or 'antagonistic hormones' are examples of responsive processes that occur post the activation of the negative feedback system to change in body temperature and are part of the warming or cooling effect concerning thermal regulation in mammals. However, these are reactions, not the main regulatory system itself. <br /><br />The 'ability to prevent dynamic equilibrium' and 'positive feedback system', on the other hand, do nothing or, in extreme cases, amplifies temperature changes rather than negating or stabilizing them.
