First Monthly Examination in TLE 10

While preparing a sunny-side-up egg, Carla noticed the thick, gel-like part surrounding the yolk. This part, known as the thick albumen, helps protect the yolk and provides protein. What is the function of the thick albumen in the egg?

• Provides fat and vitamins

• Serves as the shell membrane

• Protects the yolk and contains protein

• Acts as a fertilization site

During an experiment, Marco carefully examined the chalazae, the twisted, cord-like strands anchoring the yolk in place. He noticed that it helped keep the yolk centered. What role does the chalazae play in an egg's internal structure?

• Enhances shell strength

• Keeps the yolk stable and centered

• Regulates egg temperature

• Supplies nutrients to the embryo

Anna boiled an egg and noticed a pocket of air inside once she peeled it. She realized it was the air cell, formed as the egg cooled. Why does the air cell form inside the egg after laying?

• To supply water to the chick

• Due to contraction of egg contents upon cooling

• To allow moisture loss

• To aid in shell formation

When Benedict cracked an egg, he noticed the yolk remained firm and bright yellow. This central part contains most of the egg's fat and vitamins. What component of the egg contains the most nutrients for embryo development?

• Shell

• Chalazae

• Yolk

• Albumen

During storage, Hazel noticed that the shell protected the internal contents from damage and bacterial entry. It was made primarily of calcium carbonate. What is the main purpose of the egg shell?

• Acts as a flavor enhancer

• Provides oxygen to the yolk

• Offers structural protection

• Supplies protein

Kevin noticed a thin, white layer lining the inside of the egg shell when he peeled a boiled egg. This was the shell membrane, which acted as a barrier to microorganisms. How do the shell membranes contribute to egg safety?

• Hold the yolk in place

• Supply minerals

• Filter air entering the egg

• Serve as a microbial barrier

During a cooking class, Jenna separated the thin albumen from the yolk and thick albumen. She learned it spreads around the thick albumen and offers additional protection. Which best describes the function of the thin albumen in an egg?

• Stores waste

• Cools the embryo

• Surrounds and cushions the thick albumen and yolk

• Enhances shell quality

Brian observed that in a fertilized egg, the germinal disc appeared as a small white spot on the yolk. This is where fertilization begins. What is the significance of the germinal disc in egg anatomy?

• It protects the egg from cracking

• It serves as the fertilization point

• It forms the shell

• It stores calcium

Mia cracked an egg and saw that the vitelline membrane was tightly holding the yolk together. It helped maintain yolk integrity during cooking. What is the role of the vitelline membrane?

• Holds the albumen in place

• Keeps yolk shape and prevents mixing

• Separates shell from membrane

• Stores nutrients

During food quality testing, Ron checked the cuticle or bloom-a thin coating covering the shell. It helped prevent bacterial contamination. Why is the cuticle important in maintaining egg freshness?

• It provides insulation

• It strengthens the yolk

• It blocks bacterial entry through shell pores

• It enhances color of the shell
