I believe that you are supposed to notice that the striations in the contracted muscle fibers are much closer together than the striations in the uncontracted muscle. Therefore, it would appear that somehow the striated parts of the muscle are being pulled closer together somehow. Glycerinated muscle retains the organized structural array of myosin thick filaments and actin thin filaments, actin associated proteins like troponin and tropomyosin which regulate contraction, and the functional capacity for contraction.

Answer:
economy
Explanation:
Whichever country do we look at, there is a strong relationship between the quantity of energy that the country uses and the size of its economy. The more developed and the larger the economy of a country is, the more energy is demanded for the economy to be driven. This leads to high demand for certain natural resources that produce energy, as the industry needs power in order to function. We can easily see this if we take in consideration the biggest economies in the world, USA, China, Japan, Germany, UK, France, and then if we see how much energy each of them uses, so we will come to a conclusion that the biggest economies are the biggest users of energy.
