Positive feedback in a system is a benefit for the entire system
Answer: Option B
<u>Explanation:</u>
The positive mechanism is a stimuli that the body exhibits when in time of need which actually benefits the entire system. When required the positive feedback runs to rescue and neutralize the effect caused by the negative impact which paves a way to maintain equilibrium throughout the body.
Many examples can be cited for this like blood clotting, during labor and even in ripening of fruits. Positive and negative feedback work hand in hand to maintain homeostasis in place. Positive feedback is required to enhance the system while the negative feedback is to inhibit the activity.
Question:
Solution (explanation):
Greenhouse gases are those gases that accumulate in the Earth's atmosphere and absorb infrared energy from the Sun. This creates the so-called greenhouse effect, which contributes to the increase in the global temperature of the planet. Now, the higher the concentration of greenhouse gases, the greater the retention of heat. These extra gases increase the natural greenhouse effect and cause global warming which leads to a global change in the climate.
Answer: we can conclude that the correct answer is:
