ipn [44]
The condition of acidosis can also cause hyperkalemia because the higher H+ concentration diffuses to the intracellular fluid, pushing K+ towards the extracellular fluid. 
Hyperkalemia describes a potassium level in the blood which is higher than normal. Potassium is a vital substance to the function of nerve and muscle cells, including those of the heart. Blood potassium is normally 3.6 to 5.2 millimoles per liter.

Snezhnost [94]

Answer:

Carbondioxide gas is responsible for global warming and climate change.

Explanation:

The climate change mostly occur due to increase in the concentration of carbondioxide gas in the atmosphere. The CFCs gases causes depletion of ozone layer in the atmosphere which is responsible for prevention of ultraviolet rays coming to the earth. The burning of fossil fuels in the vehicles and industries produces huge amount of carbondioxide gas that is released in the atmosphere that allows the sunlight to the earth but block its way after reflection which remain suspended in the lower surface causes increase in temperature which leads to global warming.

Give 3 examples of homeostasis within the human body,give 3 examples of how a body system works to create or maintain homeostasi
ss7ja [257]
Homeostasis is the maintenance of internal conditions within a body. Examples of homeostasis in human includes the regulation of blood glucose level, the regulation of body temperature, or the regulation of water volume inside body.

For maintaining blood glucose concentration, the pancreas releases hormones to help the blood glucose level go back to normal. For example, if the blood glucose level is too high, insulin will be released and some glucose can be converted into glycogen and store in liver. On the other hand, if the blood glucose level is too low, glucagon is released and glycogen is converted back into glucose.

For body temperature, if the temperature is too low, our hair stands upright so more heat is trapped. In addition, our arterioles under skin contracts too so less heat is lost to the surroundings. On the other hand, if our body temperature is too high, our hair stays flat so heat can be transported away quickly, and our arterioles dilate, so more blood flows to the skin surface and more heat will be lost.

Last but not least, if the water volume in body is too low, antidiuretic hormone is released and more water is absorbed by the kidney so less water is lost. On the other hand, if the water volume is too high, antidiuretic hormone is inhibited so less water is reabsorbed back into the kidney.
