What is the primary nutrient that eggs provide for embryonic development?

1. Protein

2. Carbohydrates

3. Vitamins

4. Fats

The correct answer is: Protein

The primary nutrient that eggs provide for embryonic development is protein. During the incubation period, the developing embryo relies heavily on the high-quality protein found in the egg. This protein is essential for the growth and development of tissues, organs, and muscles as the embryo forms. It contains all the essential amino acids needed for proper cellular function and growth, making it a vital component for ensuring the successful development of the chick. While other nutrients in the egg, such as fats and vitamins, also play important roles in embryonic development, protein is crucial for building the structures that the embryo needs as it grows. Fats serve as an energy source, and vitamins are important for various metabolic functions, but without sufficient protein, the embryo would struggle to develop properly. This underscores the necessity of protein as a primary nutrient in the egg.
