The absence of any element necessary for the nourishment of that particular plant will lead to the morphological changes. And this change is an indication of a deficiency.
Of course, if the deficient element is provided to the plant in good time, the symptoms of deficiency disappear. However, if the process is delayed, eventually the plant will die.

Root nodules are found on the roots of plants, primarily legumes, that form a symbiosis with nitrogen-fixing bacteria. Under nitrogen-limiting conditions, capable plants form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia. Nodules are formed as a result of infection of the roots by soil bacteria. ... The complex process by which plant roots are infected by rhizobia is known as infection. The complex process in which nodules are formed is known as nodulation.

In the construction of various structures like bridges, columns, pillars, beams, etc. Knowledge of the strength of the materials used in the construction is of prime importance.
For example: While constructing a bridge, a load of traffic that it can withstand should be adequately measured beforehand. Or while constructing a crane used to lift loads, it is kept in mind that the extension of the rope does not exceed the elastic limit of rope. To overcome the problem of bending under force the elastic behaviour of the material used must be considered primarily.

Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy. Cellular respiration has a potential to produce between 36 and 38 moles of ATP per mole of glucose (C6H12O6). ... Each NADH [from glycolysis] produces a net 1.5 ATP (instead of usual 2.5) due to NADH transport over the mitochondrial membrane. Glycolysis has mainly two parts: First part converts glucose to Fructose, consuming 2 ATP. Second part converts the fructose into pyruvate, producing 2 ATP (the process occurs twice, so it producing a total of 4 ATP)
