Egg Anatomy And Physiology Test 2018

The correct answer is Chalaza. The chalaza is a twisted, rope-like structure that anchors the yolk in the center of the egg. It is composed of thickened strands of egg white and helps to keep the yolk suspended and protected during movement.

The correct answer is the air sac. The air sac is a small pocket of air located at the blunt end of the egg. It acts as a cushion to protect the developing embryo and provides a space for the exchange of oxygen and carbon dioxide during incubation.

The chalaza is a twisted, cordlike structure that anchors the yolk into the center of the egg for protection. This structure helps to keep the yolk in place and prevent it from moving around inside the egg. By anchoring the yolk, the chalaza helps to protect the yolk from damage and maintain its position for proper development.

The outer membrane of the egg is located between the hard shell and the inner membrane. It acts as the first protective layer inside the shell, providing a barrier against external contaminants.

The diagram provided shows different parts of an egg, and the question asks to identify part #1. Part #1 in the diagram corresponds to the shell of the egg. The shell is the hard outer covering of the egg that provides protection.

The albumen, also known as the egg white, is the structure that is equivalent to about 67% of the liquid weight of the egg. It is a clear liquid that surrounds the yolk and provides nutrients and protection to the developing embryo. The albumen is rich in proteins and water, making up a significant portion of the egg's weight. The chalaza is a twisted, rope-like structure that anchors the yolk in the center of the egg, while the yolk itself is the yellow, nutrient-rich part of the egg. The air sac is a small pocket of air located at the rounded end of the egg.

The correct answer for part #3 is the Germinal spot. The Germinal spot is a small, white spot on the surface of the yolk. It is the site where the sperm enters the egg and fertilization occurs.

A cell is the smallest structural and functional unit of an organism (living things). It is the basic building block of life, responsible for carrying out all the necessary functions for the organism's survival. Cells can vary in size and shape, but they all have certain characteristics in common, such as a cell membrane, genetic material, and the ability to reproduce. Without cells, living organisms would not be able to function and sustain life.

An egg is a cell because it is the reproductive structure produced by female organisms, including birds, reptiles, and mammals. It contains genetic material and nutrients necessary for the development of a new individual. The other options, such as a microscopic organism, an atom, or a molecule, do not accurately describe what an egg is.

The correct answer for Part #2 is the outer membrane. The outer membrane is the thin, transparent layer that surrounds the egg and provides protection. It is located between the shell and the inner membrane.

The correct answer is that the pores on the eggshell are used for air and moisture exchange. These tiny pores allow for the exchange of gases and water vapor between the inside and outside of the egg, ensuring that the developing chick has enough oxygen and that waste gases can be removed. Additionally, the pores also help regulate the moisture levels inside the egg, preventing the buildup of excess moisture that could harm the developing chick.

The inner membrane of an egg serves the function of holding in the albumen, which is the egg white, and creating the air sac. This membrane acts as a protective layer inside the egg shell and helps to keep the albumen intact. Additionally, it creates the air sac, which is important for the development of the embryo inside the egg.
