The study of how living things are classified is called dichotomous key
Cochlea.
The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the middle ear. The 8th nerve in the inner ear actually converts the mechanical energy to electrical energy for transmitting to the brain. A membrane called the tympanic membrane separates the middle ear from the outer ear. Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards. <span>
These sound waves are then transduced when it reaches the cochlea where hair-like structures interprets the sensory information and is relayed to the brain.</span>
Explanation:
<h2>Se denomina fuentes de energía no renovables a aquellas que se encuentran en la naturaleza en cantidades limitadas. No se regeneran o lo hacen en forma extremadamente lenta. Fuentes de energía no renovables son los combustibles fósiles y los isótopos radiactivos utilizados en la energía nuclear.</h2>

Answer and explanation;
Contraction of skeletal muscles;
-An action potential from a motor neuron triggers the release of Ca2+ ions from the sarcoplasmic reticulum.
-Calcium ions expose the myosin heads by binding to a blocking molecule (troponin complexed with tropomyosin) and causing it to move.
-The myosin heads form a cross-bridge with actin binding sites.
-ATP binds to the myosin heads and breaks the cross-bridge.
-The hydrolysis of ATP causes the myosin heads to change shape and swivel - this moves them towards the next actin binding site.
-The movement of the myosin heads cause the actin filaments to slide over the myosin filaments, shortening the length of the sarcomere.
-Via the repeated hydrolysis of ATP, the skeletal muscle will contract.
