The deficiency in Calcium ions causes degradation of the bones, teeth, among others. These are the primary parts of the body which contains calcium. Therefore, the lack of calcium in the body may lead to the damage of the bones, teeth. The specific deficiencies are scoliosis, polio, etc.
Answer:
Due to deficiency of Oxygen in atmosphere.
Explanation:
Oxidation is defined in two ways, 1) The addition of Oxygen and Removal of Hydrogen 2) The removal of electrons.
We will discuss the first definition for this question. The addition of oxygen to various compounds results in the oxidation of that compound.
Example: Oxidation of Methane;
CH₄ + 2 O₂ → CO₂ + 2 H₂O
In this example oxygen is added to methane and hydrogen is being removed from methane.
Oxidation type chemical weathering common more than 2 billion years ago because of less amount of Oxygen in atmosphere and the oxygen which was produced by plants reacted with different metals like Iron forming precipitates which precipitated to the bottom of oceans.

I Suggest going back in the book to look through what you want to use for your presentation as well as your key details and purpose for writing.
Explanation:
There isn't really a specific number of isotopes that elements have to have. But the isotopes are determined by the average mass of the element found in nature. And elements have varying masses because neutrons) leave and enter the atom. (neutrons are big enough that leaving the atom cause a difference in mass but electrons leaving will not, since they are so small)
