Answer:
The order is as:
1) Zygote cell
2) Blastocyst cells
3) Mesoderm cells
4) Heart Cells
Cell specialization or cell differentiation as the name indicates, is the process during which cells become specified to perform specific functions instead of generic function.
- The first cell that is formed after union of egg and sperm is called as Zygote that is not specified to perform only one function. It has all the genetic data of an organism and can develop into any specific cell with time. Zygote is an specialized cell.
- When zygote keeps dividing, after 5 days it becomes a mass or around 300 cells called blastocyst that have two main layers- an outer layer of trophoblast and inner layer of stem cells. These stem cells can be further specialized into any type or cells or an organism.
- After a time span of around two weeks, stem cells or inner layer of blastocysts further splits into three layers, ectoderm, mesoderm and endoderm. Now mesoderm is the layer which is later specialized into heart or muscle or bone cells.
- Heart cells are the excellent examples of specialized cells that give the heart an ability to pump blood and make our survival possible.

More dense liquids will want to flow further down. They have a higher weight per volume, allowing them to "Push past" the other liquids. Italian Dressing is a great example (when given time, the oil will be at the top because it is less dense then the water and other seasonings.
