Answer:
B) difference in water density
Explanation:
The deep ocean currents are the cold ocean currents. They appear in the Arctic and Antarctic circles. As the warm ocean currents come from the low latitudes toward the high latitudes, they bring in warmer water on the surface. They start to cool off though as the near the high latitudes, so gradually they become cold ocean currents. As they become cold, the water is sinking below the less dense warmer water that is coming from behind, making a turn in the opposite direction and moving as deep ocean current toward the low latitudes. Once it reaches the low latitudes, this water will get warmer, and it will move toward the high latitudes, and the process constantly continues.
Answer:
Protein.
Explanation:
In the image above, we see a molecule that is made up of several amino acids. The molecule that is made up of amino acids is protein.
Proteins are the most abundant organic macromolecules in cells, fundamental to cell structure and function. They are found in all cell types and viruses.
They are formed by amino acids linked together and joined by peptide bonds, as shown in the image above.
Of extremely high molecular weight, proteins are composed of carbon, hydrogen, nitrogen and oxygen, practically all of them have sulfur. Elements such as iron, zinc and copper may also be present.
All proteins are made up of a set of 20 amino acids, arranged in varying specific sequences.
