Which of the following correctly matches the equilibrium receptor organs to the type of equilibrium it monitors?
a. maculae/dynamic
b. equilibrium maculae/static
c. equilibrium crista ampullaris/static
d. equilibrium saccule/dynamic equilibrium

The correct answer is option B. maculae/ static equilibrium.

Explanation:

Maculae are mechanoreceptors present inside the saccule and utricle specialized for the static equilibrium detecting. Maculae use hair cells to find out the movements of the otolithic membrane occurs, which is the surrounding membrane of the macula.

The sense of the position of the head to determine the stability and posture is static equilibrium and it is determined by the maculae.

Thus, the correct answer is option- B. maculae/ static equilibrium.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
