Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.
The second stage of prenatal development begins at about two weeks after conception. at this point, the growing bundle of cells is called an embryo.
Maybe if you show the question people could answer
The correct answer is option C, the concentration of the hydroxide ion is greater than the concentration of the hydronium ion
Reason -
An acidic solution has an ability to contribute hydrogen ion. Here a hydronium ion (H3O+) has an extra H+ ion along with a water molecule. Thus presence of hydronium ion in larger amount than the hydroxide ion would make the solution acidic. Thus, the concentration of hydroxide ion should be less than the hydronium ion to make the solution a basic solution.
