Windows 7 traces back to OS/2
OS X traces back to NeXTSTEP
An operating system, or OS for short, is a collection of software that manages a computer's resources. An operating system is typically stored on the internal hard drive of the computer. Examples of popular modern operating systems include Android, BSD, iOS, Linux, Mac OS X, Microsoft Windows, Windows Phone, and IBM z/OS. All these, except Windows and z/OS, share roots in UNIX.
The reason for the exec functions being same/similar is because the Mac OS has its roots in variants of the Unix kernel.

No. Unix is a operating system that was developed by Bell Labs, now owned by Alcatel-Lucent - which spawned a whole family of Unix-like and Unix-based systems (e.g. the Linux kernel, BSD, and Solaris). Mac OS X is based on and has roots from proprietary modifications of BSD (a "flavor" of Unix-like operating systems) called Darwin.

There are a number of different types of root systems, as with many things roots do not fit neatly into man-defined groupings. The three main, recognised systems are: Tap, Adventitious (commonly associated with monocotylednous plants) and aerial root systems (such as epiphitic plants) See related link for more information
