How Much Do You Know About Eggs?

Explanation
Eggs do not contain any sugar. They are a good source of protein, healthy fats, and various vitamins and minerals, but they do not contain any sugar. Therefore, the correct answer is 0 grams of sugar in a single egg.

Explanation
Hens typically lay around 250-270 eggs in a year on average. This range is based on the natural egg-laying cycle of hens, which can be affected by factors such as breed, age, health, and environmental conditions. Some hens may lay slightly fewer or more eggs depending on these factors.

Explanation
There is no difference in the nutritional content between white and brown eggs. The color of the eggshell is determined by the breed of the chicken and does not affect the nutritional composition of the egg. The nutritional content of an egg is primarily determined by the diet of the chicken and the conditions in which it is raised. Therefore, whether an egg is white or brown, it will have the same amount of nutrients such as protein, vitamins, and minerals.

Explanation
The color of an egg yolk is determined by the hen's diet. The pigments in the food that the hen consumes are absorbed by the yolk during the egg formation process. For example, a diet rich in yellow-orange pigments like xanthophylls will result in a darker yellow or orange yolk color, while a diet low in these pigments will result in a paler yellow yolk. Therefore, the hen's diet directly influences the color of the egg yolk.

Explanation
There are nine essential amino acids in an egg. Amino acids are the building blocks of proteins, and essential amino acids are those that our bodies cannot produce on their own and must be obtained from our diet. Eggs are considered a complete protein source because they contain all nine essential amino acids. Therefore, consuming eggs can help meet our body's amino acid requirements.

Explanation
A single, large egg contains approximately 0.4 grams of carbohydrates.

Explanation
Oviparous is the correct answer because it is the term used to describe creatures that produce and lay eggs. This term is commonly used in biology to classify animals that reproduce by laying eggs, such as birds, reptiles, and most fish. Oviparous animals typically have external fertilization, where the eggs are fertilized outside the body and then laid in a suitable environment for development. This is in contrast to viviparous animals, which give birth to live young, and ovoviviparous animals, which retain the eggs inside their bodies until they hatch. Oviform is not a term related to reproduction, and oviviparous refers to animals that retain fertilized eggs inside their bodies until they hatch.

Explanation
Hummingbirds lay the smallest eggs among the given options. This is because hummingbirds are tiny birds, with most species measuring only a few inches in length. Due to their small size, their eggs are also very small. The size of an egg is usually relative to the size of the bird, with larger birds laying larger eggs and vice versa. Therefore, it makes sense that the hummingbird, being one of the smallest birds, lays the smallest egg.

Explanation
False. The eggs sold at grocery stores are typically unfertilized, meaning they have not been fertilized by a rooster. Without fertilization, the egg will not develop into a chick, so it is not possible to hatch a chick from an egg purchased at a grocery store.

Explanation
The correct answer is albumen. Albumen refers to the clear, viscous substance found in the egg white. It is rich in proteins and provides nutrients to the developing embryo. The albumen acts as a protective cushion and helps to keep the yolk in place within the egg. It also contains water to provide moisture and acts as a source of hydration for the developing embryo.
