Explanation:
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.
Mount Fuji which is Japans tallest and most famous mountain, is an active volcano in The Ring of Fire. Mount Fuji sits on a "Triple Junction" which is where three tectonic plates interact.
Answer:
Según el CERN, en los primeros instantes del Big Bang no había demasiado calor como para que se formen átomos, como el hidrógeno (el elemento más abundante del universo). En estos primeros instantes, mucho antes que se cumpla un segundo (10 a la menos 32), solo había quarks y fotones.
