Answer:
In life, muscle cells contract and relax due to the actions of two filamentous proteins (actin and myosin), which slide along each other. After death, the cells are depleted of their energy source and the protein filaments become locked in place. This causes the muscles to become rigid and locks the joints.
The complete statement is "Hypothalamus release CRH , pituitary gland release ACTH, and the adrenal glands release cortisol to complete the action in the HPA axis."
<h3>What is HPA axis events?</h3>
Generally, The key physiological mechanism that regulates the human body's stress response is the HPA axis.
In conclusion, HPA axis cascaded events are
Hypothalamus release CRH

Answer:
Experimental groups: type of dogs
Dependent variable: hearth rate
Independent variable: the amount of caffeine
