This is because of natural selection; since polar bears live in a rough environment, natural selection gives them more fur, more muscle, and can go longer without food
Pretty sure its adaptation
The purpose was to test the idea that the complex molecules of life. in this case, amino acids. could have arisen on our young planet through simple, natural chemical reactions. The experiment was a success in that amino acids, the building blocks of life, were produced during the simulation.
Answer:
ATP uses the energy from ATP hydrolysis and moves ions across the membranes.
Explanation:
- The mechanism of transportation of proteins and ions across cell membrane uses the ATPase that consume the energy from ATP hydrolysis and moves the small molecules across the cell membrane.
- The energy is used against a established electric potential or simply the chemical concentration gradient.
- This mechanism of transportation of ions is the example of active transport and a coupled chemical reaction.
