Question

Quizplus · Accepted Answer

Although an important caveat regarding vitamins is that they all work together, these conditions are mostly associated with excess of vitamin A. Extreme levels of vitamin A (high or low) can cause serious problems, even death. Diplopia is double vision; alopecia is hair loss. Increased activity of osteoclasts (cells associated with bone resorption) leads to decalcification of bones, desquamation of oral mucosa, and bone growth retardation.
