b. Gravitational constant
Explanation:
G in the universal gravitation formula represents the gravitation constant. It's value is  2.071×10⁻⁴³ s²⋅m⁻¹⋅kg⁻¹.
- The law of universal gravitation states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them". 
Mathematically, the law is expressed as: 
             F = G
Where F is the gravitational force
             G is the gravitational constant
             r is the distance 
             m is the mass 1 and 2 bodies

Answer:
Aerobic respiration process produce either 36 ATP or 38 ATP depending on the amount of NADH moles while Anaerobic produces 2 ATP. Aerobic respiration produces 32-34 ATP more
Explanation:
Aerobic respiration has 3 steps which includes; Glycolysis which produces 2ATP; Krebs cycle which produces 2 ATP and Electron Transport Chain which produces 32 - 34 ATP depending on the molecule of NADH introduced into the reaction from the kreb cycle
