Which option describes the country’s diversity in the following scenario? An African nation has been developing over the past few years. While it began as an agrarian economy, it now also has introduced manufacturing, trade, and advanced irrigation to the area. Modern technologies such as cell phones have been introduced, as well as modern agricultural techniques such as planting GMO drought-resistant crops. Construction of a new medical center is underway in the country’s capital, as well as on the country’s first institution of higher learning.

It is building its economy on more than one thing.
It is introducing modern technology like cell phones.
It is developing its agriculture to include GMO crops.

In numbering carbon atoms in the parent chain of a hydrocarbon, why would you number from right to left, rather than left to right

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
