umm how do you begin answering that ??
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].
Those molecules that we can glean information about their position via concentration gradient are called morphogens.
<h3>What is concentration gradient?</h3>
The term concentration gradient refers to the difference in the amount of substance on two different sides. This gradient could be used to glean useful information about the molecule position.
Chemical molecules that impart positional information through their concentration gradient are called morphogens.

The answer is c :) i hope its the right answer
Answer:
solid
Explanation:
When a solid is melted, for example, thermal energy is what causes the bonds within the solid to break apart.
