Answer:
The hormone glucagon secreted by the pancreatic cells cause the release of glucose from the body's storage.
Explanation:
The pancreas is an organ found inside the abdomen. This organ produces hormones such as:
- Insulin
- Glucagon
- Somatostatin
- Vasoactive intestinal peptide
Insulin and glucagon are considered primary hormones secreted by the pancreas.
Upon skipping a meal, leading to a drop in blood sugar levels, glucagon is secreted by the pancreas. This hormone then acts on the liver to stimulate the conversion of stored up glycogen present in the liver into glucose. This produced glucose is then released into the blood stream, availing the boy glucose for energy.
Answer: A solution with a pH of 7 must be neutral.
Explanation:
If a solution has pH of 7 then the concentration of 
ions and 
ions will be equal.
Thus, the concentration for both ions and ions will be 
. Generally, pH at 7 is considered as neutral.
Thus, it is concluded that a solution with pH of 7 must be neutral.
Answer:
An acid
Explanation:
» The reaction of any hydrogen ion or hydroxonium ion with a base results into an acidic solution.
For hydrogen ions:
For hydroxonium ions:
Answer:
pOH = 8.9
Explanation:
pOH+pH = 14
pH= 14- pOH
pOH = 8.9, pH=14-8.9 = 5.1
pOH = 5.5, pH=14-5.5 = 8.5
Than less pH , than more H+ ion concentration.
pH=5.1 <pH=8.5
pH=5.1 is more acidic solution
pH=5.1 or pOH=8.9 has a higher H+ concentration.
Its location is in the nucleus, because the particle is a proton or a neutron.
