Answer: High Frequency waves by method of compression bone conduction
Explanation: in this, vibration of the bones of the skull and sometimes, arguably soft tissues leads to the production of sounds. The outer and middle ear is bypassed in this method of sound production. Sound reaches the inner ear directly and its a process largely involved in designing hearing aids.
Answer:
A) rigor mortis
Explanation:
Rigor mortis is the condition of the partial contraction of muscles when the muscles cannot contract or stretch. It occurs after death as the ATP supply to muscle cells stops. The leaky cellular membranes results in leakage of calcium ions from the sarcoplasmic reticulum into the sarcoplasm. The presence of calcium in sarcoplasm triggers the binding of myosin heads to actin. The myosin heads remain attached to actin and muscles are prevented to be relaxed.
