Final answer:
Milk contains significant amounts of carbohydrates in the form of lactose, while other listed animal-derived foods such as eggs, fish, and beef have little to no carbohydrates. so, option 1 is the correct answert.
Step-by-step explanation:
Among the animal-derived foods listed - milk, eggs, fish, and beef - milk contains significant amounts of carbohydrates. This is because milk contains lactose, a type of sugar that is one of the main sources of carbohydrates in milk. While grains, fruits, and vegetables are the primary sources of carbohydrates, lactose is unique in that it is found in the milk of mammals, including humans and cows. Human milk has about 7.5% lactose and cow's milk about 4.5%. Lactose has a crucial role as it provides essential energy to infants and is also used in the production of foods and pharmaceuticals. In contrast, other animal-derived products like eggs, fish, and beef generally contain little to no carbohydrates.
Of the animal-derived foods listed, milk contains significant amounts of carbohydrates. Carbohydrates are an essential part of our diet and are found in plant-based foods like grains, fruits, and legumes, as well as dairy products. Lactose is the specific carbohydrate found in milk, making it a good source of carbohydrates.
