The upper first premolar has Mesial Marginal Developmental Groove in its mesial aspect. It also has long central groove and no supplement groves on its occlusal surface.Also 80% of the upper premolars have 2 roots. However, the upper second premolar has no MMDG and many supplemental groves. Upper second premolar is more rounded and usually has one conical root.

mandibular second premolar
two cusps and three cusps
the mandibular second premolar has 5 developmental lobes
A nano second is 1 billionth of a second. So there are 999,999,999 nano seconds difference between a second and a nanosecond

Difference between first shifting and second shifting theorem
There is no difference, the terms are synonymous.
Premolars are also known as "bicuspids". They are located between the molars and canines and are used for chewing and grinding food. They have two cusps one on each side making them easier to identify. Premolars typically come in two varieties the first premolar (also known as the "six-year molar") and the second premolar (also known as the "twelve-year molar"). The main distinguishing features of premolars are: Two cusps Located between the molars and canines Used for chewing and grinding foodThe main types of premolars are: First premolar (also known as the "six-year molar") Second premolar (also known as the "twelve-year molar")Premolars are an important part of the dental anatomy and are essential for proper chewing and grinding of food.
