<span>The answer is osteoid. It begins with unmineralized collagen fibers
and ground substance. Later it becomes a calcified matrix. The matrix is mainly
made of collagen and calcium ions. When not well mineralized, osteoblasts proliferates
hence the bone will not have the desired strength. This results to deformation
of bone causing rickets</span>
Answer:
The amount of heat energy received at any location on the globe is a direct effect of Sun angle on climate, as the angle at which sunlight strikes the Earth varies by location, time of day, and season due to the Earth's orbit around the Sun and the Earth's rotation around its tilted axis.
Explanation:
It's a problem - a problem originates when a question is asked. In this case, we have come up with a problem that needs a solution:
1. - We'll experiment in order to come up with a hypothesis (a not-valid-yet answer of what the solution to our problem is).
2. - After a series of experiments that either prove or prove our hypothesis wrong, we'll be able to come up with a theory (a valid but still discussable final hypothesis of what the solution to our problem is).
Answer:
C. / 3 - Problem.
