Answer and Explanation:
<u>D) 7 is the answer</u>
Together, the crust and the upper part of the mantle form the lithosphere, Earth's solid outer shell. This rocky, brittle layer is broken up into seven major and several minor tectonic plates (also known as lithospheric plates) that fit together like puzzle pieces.

The organism could adapt over time and find another way to satisfy this need, it could move to a new location, or the organism could eventually die off.
Answer:
15%
Explanation:
From the question given above, the following data were obtained:
Mass of sugar = 15 g
Mass of water = 85 g
Percentage of sugar in the solution =?
Next, we shall determine the mass of the solution. This can be obtained as follow:
Mass of solute (sugar) = 15 g
Mass of solvent (water) = 85 g
Mass of solution =?
Mass of solution = mass of solute + mass of solvent
Mass of solution = 15 + 85
Mass of solution = 100 g
Finally, we shall determine the percentage of the sugar in the solution. This can be obtained as follow:
Mass of solute (sugar) = 15 g
Mass of solution = 100 g
Percentage of sugar in the solution =?
Percentage = solute /solution × 100
Percentage = 15 / 100 × 100
Percentage of sugar in the solution = 15%
Answer:
OH−(aq), and H+(aq)
Explanation:
Redox reactions may occur in acidic or basic environments. Usually, if a reaction occurs in an acidic environment, hydrogen ions are shown as being part of the reaction system. For instance, in the reduction of the permanganate ion;
MnO4^-(aq) + 8H^+(aq) +5e-------> Mn^2+(aq) + 4H2O(l)
The appearance of hydrogen ion in the reaction equation implies that the process takes place under acidic reaction conditions.
For reactions that take place under basic conditions, the hydroxide ion is part of the reaction equation.
Hence hydrogen ion and hydroxide ion are included in redox reaction half equations depending on the conditions of the reaction whether acidic or basic.
