| Rubner's laws of growth | The law of constant energy consumption: the rapidity of growth is proportional to the intensity of the metabolic processes, the law of the constant growth quotient: in most young mammals, 24% of the entire food energy, or calories, is utilised for growth; in humans only 5% is utilised. (05 Mar 2000) |
| Rubner's test | A test for lactose or glucose in the urine; lead acetate is added to the suspected urine which is then filtered; ammonia is added until a permanent precipitate is formed; if lactose is present, the precipitate will take on a pink to red colour when the fluid is heated; if there is glucose, the colour will be yellow to brown. (05 Mar 2000) |
| Rubner's laws |
1. Law of constant energy consumption: rapidity of growth is proportional to intensity of the metabolic process. 2. Law of constant growth quotient: the same proportional part, or growth quotient, of total energy is used for grow

| Rubner's l. |
1. (law of constant energy consumption) the rapidity of growth is proportional to the intensity of the metabolic process. 2. (law of constant growth quotient) the same fractional part of the entire energy is utilized for growth; this fractional part is called the growth quotient.

| Rubner's t. |
1. (for carbon monoxide in blood) shake the blood with 4 or 5 volumes of lead acetate in solution: if the blood contains CO, it will retain its bright color; if not, it becomes a chocolate brown. 2. (for lactose, glucose, maltose, or fructose in urine) add lead acetate to the urine, boil, and then add an excess of ammonium hydroxide: lactose gives a brick-red color, glucose a coffee-brown color, maltose a light-yellow color, and fructose no color at all.
