Answer:
Hardness of a mineral is defined as the resistance to breaking, and density is defined as the mass of a substance per unit volume.
The density and hardness of a mineral, that is formed from through metamorphism are relatively much harder because the metamorphic minerals are formed under extremely high temperature and pressure conditions. These are high-grade minerals.
On the other hand, the density and hardness of a mineral formed through evaporation are much weaker in nature, because these minerals are formed when the water is eliminated due to the high rate of evaporation.
So, it can be concluded that the density and hardness of as mineral formed through the metamorphic process is highly stronger and harder than those that are formed through evaporation.
Zoology is the scientific study of animals.
Cellular respiration refers to an array of reactions, which generates ATP. The process of cellular respiration utilizes glucose to generate the ATP that the body requires to do essential activities. Cellular respiration can be differentiated into three segments: glycolysis, the citric acid cycle and the electron transport chain.
The essential components involved in the process are glucose, ADP or adenosine diphosphate, NAD a coenzyme used in the oxidation-reduction reaction and the reducing agent NADH.
