Lera25 [3.4K]

The constant turnover of body tissues requires the <u>chemical energy </u>supplied by carbohydrates, proteins, and lipids.

<h3> What is Chemical energy?</h3>
  • The bonds of chemical molecules contain energy.
  • Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.
  • Some of the heat energy needed for a reaction to continue can be stored as chemical energy in newly created bonds.
  • The body transforms the chemical energy in food into heat and mechanical energy.
  • At a power plant, coal's chemical energy is transformed into electrical energy. Through the process of electrolysis, the chemical energy in a battery can also generate electricity.

Naily [24]
The answer is upside-down. Mud cracks spread downward keen on soft sediment. When more sediment is eroded in, this second layer will seal the cracks underneath. Later, after the layers have toughened, the rock may be rotated upside-down and then the layers cracked. If you see edges in a mud-crack pattern, you are seeing at the side of the second layer that initially was down. You can tell that this shows edges, and not holes, through the shadow, the edges have a well-lit on one side and a shadow on the other, while holes have light and shadow on the similar side.
