The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem.(i hope this can help you) :)
The answer to that question would be false
Since feces are alkaline elements, thet raise water's pH levels. Since feces have a pH level no higher than 7, they are acidic.
A - since this beaker contains fish feces, the red litmus paper will remain red, and the blue one will start to get red
B - since there is nothing affecting the water's pH in this beaker, both litmus papers will remain the same colour, since water is a neutral liquid.

<span>It would be replaced in cases where new information and evidence would be discovered that completely contradicts the old information and evidence. Then you couldn't revise it because revision incorporates the old evidence that would now be obsolete. Then you would make a completely new theory.</span>
