Muscle fatigue during intense exercise is primarily caused by lactic acid accumulation. When oxygen supply is insufficient, muscles switch to anaerobic respiration producing lactic acid as a byproduct. This buildup lowers pH, interferes with muscle contraction, and causes the sensation of fatigue and burning.

Jatropha curcas is the chief crop used for biodiesel production because its seeds contain high oil content (up to 40%) suitable for conversion to biodiesel. It grows on marginal lands without competing with food crops, making it economically and environmentally attractive for biofuel production compared to coconut, mustard, or kikar.

Black cotton soil is a type of black soil found in the Deccan Plateau region of India. It is known as Regur because of its high clay content and characteristic color. This soil is ideal for cotton cultivation due to its moisture-retention properties.

Jaya, Padma, and Sabarmati are all high-yielding semi-dwarf and dwarf varieties of rice developed during India's Green Revolution. These varieties played a crucial role in increasing India's rice production significantly in the 1960s and 1970s.
