Answer:
tympanic membrane (eardrum)
Explanation:
The sound waves spread through the air and reach the outer ear, into which they penetrate through the ear canal. In doing so, they stimulate the eardrum, which closes the inner end of the duct. By vibrating this membrane, the vibration of a chain of ossicles located in the middle ear is induced. These ossicles transmit their vibration to the oval window, which is a membranous structure that communicates the middle ear with the cochlea of the inner ear. When the oval membrane moves, it moves the liquid (perilymph) that fills one of the three cavities of the cochlea generating waves in it. These waves mechanically stimulate the sensory cells (hair cells) located in the organ of Corti, within the cochlea in the central cavity, the middle ramp. This cavity is filled with a liquid rich in K +, endolymph. The cells embedded in the endolymph, change their permeability to K + due to the movement of the cilia and respond by releasing a neurotransmitter that excites the nerve terminals, which initiate the auditory sensory pathway.
The movement of the object is considered to be kinetic energy while the object getting warmer indicates that there is thermal (heat) energy formed.
Based on this, as the object slides across the floor, friction slows down this motion and the object becomes warmer as kinetic energy is converted into thermal energy.
Answer: A. Two waves have a displacement in opposite directions

<span>D.cellular organization

Cell is the
fundamental unit of life. It is the component of every living organism,
creature and being in the biotic environment. Thus, each of this organisms like
this panda have cells, which is grouped together to form tissues, and when tissues
form together they form the organs and then the organs systems and entirely, as
one organism. An entire organism then is what compose species. This hierarchical
structure is what every organism is totally composed of. But without the cell –these
different types of cells. There would no life.
The answer would probably be B.
