Answer:
The correct answer will be option-D.
Explanation:
Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.
Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.
This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.
Thus, option-D is the correct answer.
Answer:
The five-and-five first aid action recommended by the red cross
Explanation:
When an infant is choking and becomes unresponsive, the five-and-five approach is recommended as a first aid treatment to dislodge the material blocking the airway.
<em>The five-and-five action involves alternation between giving the subject five back blows and five abdominal thrusts until the the choking material is dislodged or the subject becomes unconscious.</em>
If the infant becomes unconscious, CPR should be performed and further help should be sought.
