Ozone layer depletion is an example of what kind of feedback loop?
Ozone layer depletion is an example of a positive feedback loop, where the thinning of the ozone layer allows more harmful UV radiation to reach the Earth's surface, leading to further ozone depletion.
What is type of feedback in which a given action promotes more of the same?
The type of feedback that promotes more of the same action is positive feedback. It occurs when the result or outcome of an action increases the likelihood of that action being repeated or continued. Positive feedback reinforces and encourages the behavior or action that produced it.
What Feedback stimulates your body to respond in the same as a stimulus?
Positive feedback stimulates the body to respond in the same way as a stimulus. This occurs when a change or response is amplified, leading to an even greater change in the same direction. An example is the process of childbirth, where the release of oxytocin intensifies contractions, further promoting the release of more oxytocin. This feedback loop continues until a specific outcome is achieved.
What are some examples of a positive feedback loop and a negative feedback loop?
The most common by far is negative feedback, pretty much every hormone works through negative feedback. Take for example tiroxine: low levels of tiroxine induce production of TRH and TSH which in time increase production of tiroxine, and when the levels of tiroxine are high, it lowers the production of TRH and TSH, lowering production of tiroxine as well. Another example would be insulin: when blood sugar levels rise, the pancreas produces more insulin, and once it takes effect and blood sugar levels lower, the pancras stops the increased production. Positive feedback on the other hand is more rare, an example would be childbirthing, when the baby stretches the cervix, it induces production of oxytocin in the pituitary gland, which causes the contractions of the uterus, pushing the baby out and stretching the cervix even more, making the pituitary gland produce even more oxytocin
When the body becomes dehydrated a chemical signal is sent that causes nephrons in the kidneys to absorb more water and excrete more salts This is an example of a?
feedback loop
What happens during positive feedback loop?
During positive feedback loop, e.g. a gland activates a hormone and the hormone in turn activates the gland. After the hormone knows that it is being activated by the gland, the hormone signals the gland to produce more of the hormone. This is positive feedback loop.
Ozone layer depletion is an example of what kind of feedback loop?
Ozone layer depletion is an example of a positive feedback loop, where the thinning of the ozone layer allows more harmful UV radiation to reach the Earth's surface, leading to further ozone depletion.
Is the ADH feedback loop an example of positive or negative feedback?
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
Why is erosion considered a positive feedback loop?
Erosion is considered a positive feedback loop because as soil is eroded, it reduces the vegetation cover on the land, which makes it more susceptible to further erosion. This leads to a cycle where erosion begets more erosion, creating a self-reinforcing process that can significantly alter landscapes over time.
Is dehydration positive feedback?
Dehydration is not an example of positive feedback. Positive feedback loops amplify or reinforce a pathway or process, while dehydration is a state where the body lacks adequate water, leading to negative effects on various bodily functions.
Is the ADH feedback loop an example of positive or negative feedback explain?
The ADH feedback loop is an example of a negative feedback loop. Negative feedback loops occur when the output of a system acts to oppose the changes to the input of the system. This is the case with ADH because when there is not enough water, the hypothalamus and pituitary gland work to release ADH so that the body can retain more water.
What is a positive feedback loop increasing carbon dioxide?
The Oceanic Solubility Pump.Oceans absorb carbon dioxide (CO2) from the atmosphere.As the oceans get warmer, they absorb LESS CO2 than before.So MORE CO2 remains in the atmosphere.So the atmosphere gets warmer.This makes the oceans warmer.So they absorb less CO2. And so on.This is a positive feedback loop which increases the levels of carbon dioxide in the atmosphere.
How does a neuron create a positive feedback loop?
A neuron creates a positive feedback loop by amplifying and reinforcing the initial signal it receives. When a neuron receives an excitatory signal, it triggers an action potential that leads to the release of neurotransmitters, which further activate neighboring neurons, leading to a continuous cycle of activation and signaling. This amplification process results in a self-reinforcing loop that can enhance the strength and duration of the signal being transmitted.
A blood clot stimulating the formation of more blood clotting is an example of?
Postive feedback
Is predator prey relationship an example of positive feedback loop?
No, a predator-prey relationship is not an example of a positive feedback loop; rather, it is an example of a negative feedback loop. In this relationship, an increase in prey population leads to more food for predators, resulting in an increase in predator numbers. However, as predator populations rise, the prey population may decline due to increased predation, which in turn can lead to a decrease in predator numbers when food becomes scarce. This cyclical dynamic helps maintain balance in the ecosystem.
Definition of negative feedback and positive feedback?
A: Any feedback that contributes to the input is positive feedback any feedback that subtract from the input is negative feedback
What hormones are regulated by positive feedback under certain circumstances?
Oxytocin in the process of giving birth. Oxytocin causes uterine contraction, which causes the baby to push up against the cervix, which causes more oxytocin to be released. And the cycle continues until the baby is born.
