According to US Energy Information Administration data, urban U.S. households own an average of 1.8 vehicles each, compared with
Dmitrij [34]

Answer:

transportation

Explanation:

looking at nighttime satellite photos that show dark landscapes illuminated by glowing urban dots. On the surface, these seem like clear evidence of city dwellers' oversized energy footprints.

And when comparing big cities and small towns directly, a Philadelphia, Pennsylvania, obviously dwarfs the power consumption of a Philadelphia, Tennessee Urban and rural populations use energy differently, though, which complicates such broad comparisons.

Despite hosting regular traffic jams, cities win the head-to-head efficiency matchup in transportation thanks to their mass transit systems and denser layouts, which promote walking and bicycling. Small-town and suburban residents usually have to drive themselves to get around, which isn't cheap.

According to EIA data, urban U.S. households own an average of 1.8 vehicles each, compared with 2.2 for each rural household. Urban families also drive about 7,000 fewer miles annually than their rural counterparts, saving more than 400 gallons of gasoline and roughly $1,300-$1,400 at current gas prices.

When muscle tissue is exercising under anaerobic conditions, the production of ______ is important because it ensures a continuo
MatroZZZ [7]

Given what we know about the biological mechanisms behind anaerobic exercise, we can confirm that the production of lactate ensures a continuous supply of NAD.

In order for us to undergo any physical exercise, it is imperative that we are able to produce energy within our cells. The energy used by cells is in the form of a molecule by the name of ATP, which is produced primarily through a process known as <em>Glycolysis</em>.

This is relevant given that in order for glycolysis to happen, a key protein is required known as NAD+. Lactate is produced from pyruvate only under anaerobic conditions because these are conditions that lack oxygen which is the only other source of NAD+, therefore, pyruvate must be converted to lactic acid to make it possible to continue glycolysis and the production of ATP.
