The toxic condition characterized by retention of
nitrogenous substances in the blood is called uremia. Uremia is a toxic condition caused by
retention in the blood of nitrogenous waste products normally excreted in the
urine. Acute renal failure denotes a
sudden onset of renal failure, such as that caused by an accident, certain
drugs or poison. The kidneys may recover or the damage may be permanent. If the
kidneys stop functioning this condition is what they called uremia, therefore
the body is full of extra water and
waste products, leading to swelling in the hands or feet, fatigue and weakness.
End-stage renal disease refers to when the kidneys have lost all or nearly all
function.
The water will move out of the fish by osmosis due to existence of concentration gradient .
The changing quantities in an experiment are called variables. A variable refers to any trait, factor, or a condition, which can prevail in distinct amounts or kinds. An experiment generally exhibits three kinds of variables: independent, dependent, and controlled.
The independent variable refers to the one, which is modified. On the other hand, the dependent variable is implied to observe that how it reacts with the change made to the independent variable. The controlled variables refer to the quantities, which one wants to remain constant.
In the given case, that is, heating a cup of water to witness that whether the sugar will get more easily dissolve. In this, the independent variable refers to the temperature of the water determined in degrees Centigrade. The dependent variable refers to the amount of sugar, which dissolves completely measured in grams.
In this, the controlled variables are stirring and type of sugar. As more stirring might elevate the amount of sugar that dissolves, and different kind of sugars might dissolve in distinct concentrations. So, in order to make sure a fair test, there is a need to keep these variables similar for each cup of water.
