Maintaining Homeostasis. The process in which organ systems work to maintain a stable internal environment is called homeostasis. ... Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). ...
Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
There are lots of different hormones in the human body that serve lots of different functions, but some are used to maintain homeostasis of various physiological parameters, like blood glucose levels. Blood glucose levels are regulated by two opposing hormones: insulin and glucagon.
The holocene epoch was the first time in history of the world that human activity caused global changes, starting around 9,000 BC when they started slowly to move towards living in cradles of civilization and writing history down in 3,000 BC.
Bones are made up of Calcium Phosphate given by the chemical formula,
. When bones are kept in Hydrochloric acid, given by the chemical formula, HCl, they become soft because the calcium compound present in the bones changes its form. The following double displacement reaction takes place when the bones are kept in HCl,
---> ![CaCl_{2} + H_{3}PO_{4}](https://tex.z-dn.net/?f=%20CaCl_%7B2%7D%20%2B%20H_%7B3%7DPO_%7B4%7D%20)
Calcium chloride is water soluble, and gets washed away. This makes the bone thin and soft.
