Answer:
Protostomes: Protostomes may be defined as the organisms in which mouth develops first from the blastopore. These organisms shows the determinate and spiral cleavage. The coelum may be defined as the solid mass of the cell that are derived from the mesoderm.'
Deuterostomes: Deuterostomes may be defined as the organisms in which naus develop first from the blastopore. These organisms show indeterminate cleavage and coelum is derived from the archenteron.
Triploblast : Both protostomes and deuterostomes are triploblastic animals,
None of them is diploblastic in nature.
The phenotype is the observable traits of an organism. You know, the behavioral trait, development, that sort of thing.
Answer: It is a selective and differential medium.
Explanation: Selective medium is used to select the growth of certain bacteria whilst inhibiting the growth of another by preparing a medium with ingredients that will only select a specific growth of intended microbe. When closely related bacteria had been selected, they can further be differentiated by the way they utilize the medium. In this case staphylococcus aureus was first selected using sodium chloride with which only this bacteria can tolerate i.e halophilic (strives in salty environment). It was also further differentiated by its ability to ferment sugars changing the colour of the pH indicator chemical.
Density dependent would be the answer
