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.
Answer:
D
Explanation:
DNA pairs with adenosine, thymine, cytosine, and guanine
RNA pairs with uracil, adenosine, cytosine, and guanine
Answer: I believe <u>option A.</u> is correct.
Explanation: When you look at both the cells, you see that cell A. shows the molecules diffusing in and out of the cell membrane. Where as, cell B. doesn't show as much.
Hope I could help! :)
Rain and snow will occur in low air pressure.
When the pressure of the air is low, the air rise upward in the atmosphere and gets cool and condenses. The condensation causes the formation of clouds from water droplets and snow particle around the dust particle in the sky and at last the the condensation of water vapor causes the formation of rain.
