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.

Answer:
Each individual is a member of a population. Each population is made up of a group of individuals of the same species that occupy the same environment and interact with each other. Many different populations together make up a community, and many different communities interact with one another in an ecosystem.
So prey is needed for a predator to eat. When there is less prey the predators community goes down as well if a group of predators die like all of them then the prey community jumps cuasing food to go down and kill everything.
Answer:
Injury to the alveolar-capillary membrane
Increased alveolar-capillary permeability
Decreased lung compliance
Explanation:
Acute respiratory distress syndrome (ARDS) is a serious health problem that affects the lungs, which is caused by significative amounts of fluid that fill the air sacs. ARDS may be caused by distinct conditions such as, for example, pneumonia, sepsis, and traumatic injury. ARDS is a type of respiratory failure that results in decreased oxygen levels and increased carbon dioxide (CO2) concentration into the bloodstream.
