I believe the single most important city was Babylon, which is currently 80 km south of present day Baghdad. However there were other important cities.

But for mesoameria, it was Teotihuaca.
In 2-bromobutane, the carbon atom bonded to the bromine atom (CHBrCH3) is the stereogenic center. To determine its optical activity, you need to analyze if there is a plane of symmetry or a center of symmetry within the molecule. If the molecule is chiral (lacks a plane of symmetry or center of symmetry), it will be optically active.
The nucleus controls what the cell does because it contains the genetic instructions of the cell.
The integrative center for autonomic activity is primarily located in the brainstem, specifically in the medulla oblongata. This area regulates essential autonomic functions such as heart rate, blood pressure, and digestion. Additionally, other regions in the brain, such as the hypothalamus and limbic system, also play a role in coordinating autonomic responses to various stimuli.
Some isomers lack optical activity because they have a plane of symmetry or a center of symmetry that results in the molecule being superimposable on its mirror image. This makes them achiral and unable to rotate the plane of polarized light, thus lacking optical activity.
Glycine is an example of an optically inactive amino acid because it does not have a chiral center and therefore does not exhibit optical activity.

The Leapfrog Activity Center is not a place but rather an activity center to be used in the home for your baby. There are many different styles and they average $120-$165.

The center of activity in a Roman city was called a forum.
It gave them a means of keeping records, which helped commerce, government and religious activity.
Sumerian citystates were originally theocracies.
Community activity center.
A ziggurat was typically the center of activity in ancient Mesopotamian cities, serving as a religious and administrative hub. These stepped structures were dedicated to deities and often housed temples at their summits, where priests performed rituals. In contrast, pyramids, primarily associated with ancient Egypt, served as monumental tombs for pharaohs and were not central to daily city life. Therefore, ziggurats played a more active role in the social and civic functions of their respective cities.
