Answer:
Look at my explanation (I have notes on this)
Explanation:
•They divided people off based on their purity
•Government: they were ruled by kings
•Their writing contained 400 symbols, both pictographs and phonetic characters
•Their cities had high walls and laid out in grid system (Citadel was a watch tower and one of the major buildings)
•They had polytheistic religion called Hinduism
For starters, the left image is a plant cell and the right image is an animal cell.
The black dots in both images would be drawn to the nucleus. All cells have nuclei. The black oval in the right image would be drawn to the cell membrane. Only animal cells have these. The rectangle with a gap would be drawn to the cell wall. Only plant cells have cell walls. The space surrounding the nucleus in both cells would be drawn to cytoplasm. All cells have cytoplasm. The dotted circles would be drawn to chloroplast. Only plant cells have these.
Hope I could help!
