Some body help me,
* Describe the range of sense receptors present on insect antennae
* What is the function of the utricles and saccules?

For the first question try:

You will have to search the article a bit but the information is there.

For the second questions I can tell you that the utricles and saccules are sensitive to linear acceleration.

Good luck

Range of receptors... wow great query



Well receptors are proteins... and the range of proteins is limited and they get denatured after the critical point

Thye act best on optimal points..


As far as the antenae,utricles and saccules are concerned,they are sensitive to air currents ,some higher range wavelengths and lower energy radiations.
