The amniotic sac holds a developing foetus when it is in the womb. The fluid it contains (the amniotic fluid) acts to protect the foetus. Think of a goldfish in bag of water - even if you accidentally knock the bag the fish doesn't feel anything. The same principle applies.

What accounts for the lighter appearance of the pro-amnoin?

The lighter appearance of the pro-amnion is due to its different composition compared to the amnion. The pro-amnion consists of a loose network of cells and fibrous material, which allows it to appear less dense and lighter in color. Additionally, the pro-amnion is more vascularized than the amnion, contributing to its lighter appearance.


What is the function of th membrane that encloses the embryo?

Membranes forms a protective sac that surrounds the embryo?

The embryonic sac, or amniotic sac, is composed of a membrane called the amnion. The amnion serves to protect the embryo by providing a physical barrier against external threats and a cushioned environment for development. Additionally, the amnion secretes amniotic fluid which helps to regulate temperature, provide buoyancy, and prevent desiccation of the embryo.


What is the membrane that forms a sac around an animal embryo?

What change takes place in the liquid inside a thermometer when it is placed into somthing cold?

The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.
