Answer:
According to the diagram, step 3 indicates the S phase of cell cycle, which corresponds to the DNA replication phase.
Explanation:
In the S phase of the cell cycle the nucleus contains twice the amount of its genetic charge, due to increased DNA replication, resulting in each chromosome forming two chromatids.
This is a relatively long phase, and is part of the preparation process that occurs before an imminent division. In the diagram it is indicated by the number 3.
The S phase is named for the abbreviation of <em>Synthesis</em>.
Answer:
The most appropriate kingdom would be Animalia.
The common characteristics of the kingdom Animalia may include:
- The organisms of this kingdom are eukaryotic. Thus, they have a well-developed nucleus and other cell organelles like mitochondria et cetera.
- They are multi-cellular organisms, that is, they are composed of many cells. They may show body organization like cells→ tissues→ organs→ organ systems→ organism
- Unlike plants, they lack chloroplast and cell walls.
- They are usually heterotrophic.
Thus, the cell can be classified as Animalian cell.
