1. How do negative feedback mechanisms work to maintain dynamic homeostasis for a particular condition?
Negative feedback is a control mechanisms that reduces the stimulus. The interaction between external conditions attempting to change the internal conditions and the internal mechanisms blocking these changes is what makes homeostasis a dynamic equilibrium. An example of this is sweating when the body exercising and producing heat. This causes one’s nervous system to trigger sweating which will reduce the body temperature from the evaporation of the moisture, showing the internal conditions of sweating blocking out the external condition of temperature increase.
2. How do Positive feedback mechanisms work to maintain dynamic homeostasis for a particular condition?
Positive feedback enhances a stimulus rather than to slow it down. Positive feedbacks allow animals to complete a process, such as a baby’s head being placed against a uterus of the mother. The pressure of the baby’s head sends receptor signals that causes to uterus to open wider and allows for the baby to come out, allowing the successful completion of birth.
3. Explain the effects of alteration in the mechanisms of feedback. Use one of the following to help illustrate your explanation.
Though the main function of blood in the circulatory system is to transport internal materials, the blood alternates from its its main function by having platelets. While the red cells carry oxygen to the different areas of the body and the white cells fight off infection, the platelets keep the blood from clotting to main function the blood cell function and keep the body in homeostasis.
4. Explain how organisms respond to changes in their environment through behavior and physiological mechanisms.
When the body temperature in humans drop, the body tries to stop heat loss mechanisms and activate heat saving mechanisms while heat generating mechanisms such as shivering occurs. Sweating is similar to this process, however it occurs when the body experiences an increase in temperature and the internal signal turn off the heat saving and turn on the heat loss mechanisms.
