Answer : Infrared rays have a shorter wavelength than radio waves.
Explanation :
The wavelength of Infrared rays is 700 nm – 1 mm
The wavelength of X- rays is 0.01 nm – 10 nm
The wavelength of UV rays is 10 nm – 400 nm
The wavelength of radio waves is 1 meter – 100,000 km
The wavelength of gamma rays is less than 0.01 nm
So, from the above data it is clear that the wavelength of the infrared rays have a wavelength shorter than the radio waves.
Hence, the correct option is (C) " radio waves ".
Answer:
Negative feedback caused his pancreas to produce more insulin.
Explanation:
Positive feedback is a feedback that causes an increase due to change, that is it results in more product while negative feedback is a feedback that causes a decrease due to change, that is it result in lesser product.
Blood sugar control in the body is a negative feedback, because as the blood sugar increases, the nerves sense a change which causes the pancreas to secrete insulin until homeostasis and then the secretion stops.
