Select the best statement relating to the following reaction: 2 mno2 (s) + kclo3 (aq) + 2 koh (aq) → 2 kmno4 (aq) + kcl (aq) + h2o (l) h in koh is oxidized. mn in mno2 is oxidized. cl in kclo3 is the reducing agent. cl in kclo3 is the oxidizing agent. kclo3 is the reducing agent.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.
