The following substance are excretory products in farm animals except l. blood ll. sweet lll. urine
Answer Details
The correct answer is (a) l only. Blood is not an excretory product, as it is a vital fluid in the circulatory system that carries oxygen and nutrients to the body's tissues and removes waste products. Sweat and urine are excretory products, as they contain metabolic waste products such as urea, salt, and other substances that are eliminated from the body.
