Answer:Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar
Explanation: homoestasis is the process by which the body keep it's internal environment constant, regardless of change in the external environment. The human body has a normal range in which it's system operates and it uses homoestasis to keep these at constant.
Homeostasis could be positive or negative. It usually involves a sensor which detects the changes in the body and passes the information to the control center, a control center which receive information from the sensor and sends signals to the effectors and the effector which acts on the information sent by the control center to effect normalcy.
In this case, when a person eats food,he gets glucose. Blood sugar most be kept at constant so the endocrine system release the hormone insulin. Insulin helps to convert glucose to glycogen, which is the form it can be stored in the liver
When the blood sugar levels is low, the brain which is the control center causes glucagon to be released . This hormone converts glycogen to glucose
The answer should be neutrons electrons and protons
<span>Then amount of energy required to break the attractions among the solute particles and among the solvent particles is </span>less than the energy released as attractions form between solute and solvent particles.
No reaction will occur because magnesium is more reactive than zinc. If you did the reverse ( magnesium particles in zinc sulphate solution) than a reaction will occur in which the zinc will be displaced from solution.
Answer:
d = PM / RT
Explanation:
Density can be measure from,
PV = nRT
in this equation
P = pressure
V = volume
n = number of moles
R = general gas constant
T = temperature
It is known that,
number of moles = mass/ molar mass
n = m/M
We will put the n= m/M in PV= nRT
PV = m/M ×RT ......... (1)
density = mass/volume
d= m/v
By rearranging equation (1)
P V/m = RT/M
P = m/V×RT/M
P = dRT/M
d = PM / RT
