Answer:
Molecules.
Explanation:
Molecules are the items that attach on the inside of the mineral to give the mineral its shape. The molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that, these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
They can estimate how old the universe is by testing rocks from different planets and comparing ages and comparing with our earth so since we know approximately how old are earth is we can tell how old the universe is
Hypocalcemia can result from the following factors:
- Lack of vitamin D or vitamin D resistance
- post-surgery, hypoparathyroidism
- due to autoimmune illness or hereditary causes of hypoparathyroidism
- Inadequate vitamin D levels are brought on by renal disease or advanced liver disease.
- Hypoparathyroidism, also known as pseudohypoparathyroidism
- Parathyroid gland metastatic growth or heavy metal (copper, iron) invasion
Acute hypocalcemia is characterised by neuromuscular irritability. Cardiovascular symptoms of acute hypocalcemia are possible. Chronic hypocalcemia is frequently brought about by insufficient parathyroid hormone or vitamin D levels or by hormone resistance.
The right course of treatment depends on knowing the difference between acute and chronic hypocalcemia and between hypocalcemia with no symptoms and hypocalcemia with severe symptoms.
