<h3><u>Answer and explanation;</u></h3>
- Density plays an important role in the study of Earth. It affects Earth's climate, plate tectonics, and subduction.
- <em><u>Subduction occurs at the convergent plate boundaries. Density plays a major role for subduction to take place. Subduction is driven by the excess density of the lithosphere compared to the underlying asthenosphere.</u></em>
- <em><u>Oceanic plates are denser and colder than continental plates, because the ocean cools them. Subduction can occur between an oceanic plate and a continental plate, or two oceanic plate or two continenetal plates.</u></em>
- During subduction between oceanic and continental plates, mantle convection drags the denser oceanic plate downwards and forces it down into the asthenosphere.
- During subduction between two oceanic plates, mantle convection drags the older, denser oceanic plate downwards and forces it into the asthenosphere.
- During subduction between two continental plates, there is no mantle convection, because the two plates are of similar densities.
You were right, the answer to this is C.
The factors which determine the shape of protein are;
1. Order of amino acids.
2. The number of amino acids which are used.
The order of amino acids or in other words primary structure determines how folding of amino acid chain or its tertiary structure.
Protein is termed as the chemicals which are found in all cells which are used for growth and work. Protein in the human body includes hemoglobin and collagen.
