| 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.

| 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.
