Answer:
The correct answer is option b. "The lipid bilayer is a solid at body temperature, thus protecting the cell".
Explanation:
The fluid mosaic model describes the fluid character of the cell's membrane structure as a dynamic arrangement of components that include phospholipids, proteins and carbohydrates. One of the principles of the fluid mosaic model is that the lipid bilayer that comprises the cell's membrane is solid at body temperature, thus it functions as a protective mechanism for the cell. The higher the temperature, the more fluid the cell membrane is.

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:
B
Explanation:
The only difference between the speed and the velocity is that the velocity tell us about magnitude and direction but speed tell us about magnitude only. Hence, the correct option is,
