Stomata play an important role in photosynthesis as they allow the plant to absorb carbon dioxide from the environment. In exchange, stomata allow oxygen, which is a waste product of photosynthesis, to be released. In the process, water vapor is also lost as the internal parts of the leaves are exposed. To reduce exposure, stomata are found on the underside of the leaves. They are protected from the sun as excessive heat can increase the rate of water vapor leaving and thus wither the plant. Stomata also have guard cells around the epidermis that close when too much water is being lost.
Isotonic solution.
Since it has the same salt concentration as the cell the solution is neither hypotonic or hypertonic.
Conductive hearing loss occurs from either (1) blockage from the external ear or (2) damage to any components of the middle ear; hence the answer here is false. Hearing loss that results from damage to the inner ear or the vestibulocochlear nerve is called <em>sensorineural hearing loss</em>.
<em>The most common cause of sensorineural hearing loss is noise-induced hearing loss due to prolonged exposure to high decibel environments (i.e. machine workers). </em>
The second one is the answer
