Answer:
sarcoplasmic reticulum deteriorates and ATP production is stopped
Explanation:
Rigor mortis is the third stage of death characterized by stiffening of joints and muscles in body. The stiffening occurs because muscles are not able to return to the relaxed state. There are two reasons for rigor mortis, depletion of ATP and increase in calcium concentration in cytosol. Due to these factors the actin-myosin crossbridge is not able to break and the muscles remain in contracted state.
Sarcoplasmic reticulum deteriorates and calcium is released into the cytosol. Sarcolemma ( covering of muscle fiber ) also breaks down releasing extra calcium into the cytosol. Calcium is responsible for formation of actin-myosin cross bridge and when its concentration increases the bridge is formed continuously leading to stiffening of muscles and joints.

Because of the severe impact that we impose on the land, air, and water, conservation has
become increasingly important.
Conservation is using natural resources wisely and not contributing to pollution of the land, air or water. Human activities can benefit the environment and help preserve resources.
Conservation can include small-scale clean-up projects along roadways or building fences to prevent dune erosion to large-scale beach renourishment. Planting trees is another way to support conservation as trees are too often removed without being replanted.
The phrase “Reduce, Reuse, and Recycle” has been a catch phrase of the late 20th and early 21st centuries.
