The best answer - dermal tissue.
Dermal tissue in plants forms the first line of defense against physical damage and infection from the outside world.
Dermal tissue covers the outside of the plant, except in woody shrubs and trees, which have bark. The most common cell type in dermal tissue is epidermal cell. Generally, a thin waxy layer called a cuticle covers the epidermal cells and protects them.
Other cells in the dermal tissue are guard cells that surround the stomata, which are openings in the leaves. Gases enter and leave the dermal tissue through the stomata.
Answer:ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street. But cellular respiration is slightly more complicated than just converting the energy from glucose into ATP.

Answer:
The frequency theory of hearing
Explanation:
The frequency theory of hearing contends that the perception of a sound's frequency depends on how often the auditory nerve fires.
The frequency theory of hearing pinpoints that the frequency of the auditory nerve's impulses coincides to the frequency of a tone, which makes it easy to distinguish its pitch. It causes the neural signals speed to go in line with the brain to distinguish the pitch.
Place theory says that the perception of pitch is connected with vibration of certain portions of the basilar membrane, and the frequency theory says the perception of pitch is connected with the frequency at which the whole basilar membrane vibrates.
