Answer;
As liquid water freezes, the molecules arrange themselves in a way that takes up more space than liquid water. What would most likely occur if the arrangement of frozen water molecules required less space than that of liquid water molecules? A).The density of ice would be greater than the density of liquid water, and ice would not float. B). Ice would form in layers, and liquid water would get trapped in between the layers. Liquid water would have a higher specific heat, making it less likely to undergo vaporization. C).The freezing point of water would decrease, making ice more difficult to form.
Answer:
Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2).

Answer:
Pepsin is the gastric enzyme that initiates protein digestion.
The pepsinogen is first produced by the stomach lining. This is the inactive form. It reacts with is the stomach acid ( dil Hcl) to form pepsin(active form).

The Amino acids formed from the breakdown of Protein helps in the synthesis of enzymes, hormones and other biological cell components.
Amino helps in the replacement of worn out tissues.
It also helps in mental development and reduction of fatigue.
