Answer:
Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. ... A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow. I hope this helps!
First move the x from the right side to the left by subtracting. 3x-6+2x-x=-2. combine like terms. 4x-6=-2. add six to both sides. 4x=4. divide 4 on both sides. x=1. hope this helped!
The denser plate
Explanation:
When two plates forms a subduction zone, the denser plate will subduct and dive into the underlying mantle below.
Subduction zone occurs along a convergent margin when two plates of different densities collides.
- When two plates of different densities collides, the denser plates subduct.
- This is because the density of the mantle below is less than its own density.
- Most times, oceanic plates usually subduct during plate convergence.
- Oceanic plates are denser compared to continental plates.
