How is the negative feedback relationship of clouds and temperature different from the positive feedback relationship of water vapor and temperature?
In the negative feedback relationship between clouds and temperature, clouds tend to cool the atmosphere by reflecting sunlight back into space. This helps regulate temperature.
In contrast, the positive feedback relationship between water vapor and temperature involves water vapor trapping heat in the atmosphere, leading to a further increase in temperature. This can create a cycle of warming.

Describe a negative feedback system?
Q: describe the negative- feedback system subject: Science A: To control the amount of hormones that are in your body, the endocrine system sends chemical messages back and forth within itself. This is called a negative- feedback system. example: it works much the way a thermostat works. when the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. once the furnace has raised the temperature in the room to continue to stay off until the thermostat signals that the temperature system controls the level of glucose in your bloodstream. ur wlcm (: SnazzyChazzy <33
What does it signify if the feedback on my work is negative?
Negative feedback on your work typically signifies areas for improvement or areas where your work may not meet expectations. It can be an opportunity for growth and learning to enhance your skills and performance.
Can you get a negative kelvin temperature?
No, according to the laws of thermodynamics, it is not possible to achieve a negative Kelvin temperature because it would imply an object has negative energy. The concept of negative temperature in the Kelvin scale does not exist.
How diffusion coefficient depends on temperature?
The diffusion coefficient generally increases with temperature. This is because higher temperatures lead to greater thermal energy, which enhances the movement of particles, resulting in increased diffusion rates. The relationship between diffusion coefficient and temperature can often be described by Arrhenius equation or by simple proportional relationship in many cases.
How and why does temperature affect the refractive index of a liquid?
Yes, the refractive index of a liquid often is different at different temperatures (usually negative; e.g. It goes down as temperature goes up), although typically the effect is very nominal. However, that is not to say that there is a constant relationship between Ref index & temperature. Refractive index is proportional to the square roots of electrical permittivity and magnetic permeability. These factors may change with temperature, but not linearly, and therefore RI does not have a simple relationship with temperature.
How does negative feedback help regulate your internal body temperature?
it helps your internal body temperature alot. The negative feedback heats the inside of you so you don't freeze. Its pretty simple when you think about it. Negative feedback is like a thermostat.
Why is temperature control is regarded as an example of a negative feedback?
Temperature control is an example of negative feedback because the body continually works to maintain a stable internal temperature. When body temperature rises, thermoreceptors signal the brain to trigger mechanisms such as sweating to cool down the body. Conversely, when body temperature drops, thermoreceptors signal for mechanisms like shivering to generate heat and raise the temperature. This feedback loop helps regulate the body's temperature within a narrow range.
When body temperature rises a center in the brain initiates physiological changes to decrease the body temperature is an example of negative feedback or positive feedback?
This is an example of negative feedback because the body is working to reverse the initial change in order to restore homeostasis. When the body temperature rises, the brain triggers responses such as sweating and vasodilation to help cool down the body and bring the temperature back to the normal range.
Is thermoregulation in humans regulated through positive or negative feedback systems?
Thermoregulation relies on negative feedback. Negative feedback works to return a system to homeostasis by reducing a stimulus, such as a change in temperature. By contrast, positive feedback systems amplify or speed up a response.
Compare and contrast negative and positive feedback mechanisms and give some examples?
Negative feedback mechanisms work to maintain homeostasis by reversing a change in a system, while positive feedback mechanisms amplify and reinforce a change. An example of negative feedback is the regulation of body temperature – if body temperature rises, mechanisms kick in to lower it; whereas in positive feedback, childbirth contractions become stronger and more frequent to facilitate delivery.
Identify the concept behind negative feedback system?
normal body temperature is about 37degree c . if it is increased or decreased ,it will be maintained by the negative feedback mechanism . gain=correction/error
What does your body maintain though negative feedback?
Your body maintains homeostasis through negative feedback. This somewhat like using a thermostat to maintain a narrow range of temperature in the house.
Which feedback mechanisms maintain equilibrium of systems like turgor pressure temperature and chemical reactions?
both negative and positive feedback
What is an example of a negative feedback in human body?
example of negative feedback example of negative feedback
What are four conditions in the cell that must be kept in the homeostatic balance?
- temperature - negative feedback loop - positive feedback loop - water balance
When the body temperature rises a center in the brain initiates physiological changes decrease the body temperature. this is an example of?
Negative Feedback
Is a thermostat an example of positive or negative feedback?
Negative feedback is a reaction that causes a decrease in function. Using a thermostat, it senses the temperature of an area and responds by either turning on or off the heater or air conditioner.
