Why does the earth have different layers?

Biology
1 answer:
Aliun [14]3 years ago
6 0

Answer:

The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.

Select all the molecules that have stored potential energy and that can be used in aerobic respiration to generate atp.
Masteriza [31]

Carbohydrates, lipids, and protein have potential energy, and can be used in aerobic respiration to generate .

Carbohydrate- A carbohydrate is a naturally occurring substance or a derivative of one, made composed of molecules of carbon, hydrogen, and oxygen. The most prevalent organic compound is a carbohydrate, and all life depends on them.

Lipids- Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water.

Protein- Large, intricate molecules known as proteins serve a variety of vital functions in the body. They are crucial for the construction, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.

This example reflects the food chain.
<span>The food chain describes relationships among the organisms by showing how the organisms are related to each other by the food they eat. The food chain contains levels and each of them presents a different trophic level (position of the organism in that chain). There is reliable energy transfer through each stage of the chain. Not all the energy at one stage is absorbed by the organism at the next stage but, the amount of energy from one stage to another decreases.</span>
