Inertia is the opposing of gravity so...
<span>the activity that does NOT improve stability is: A. maintaining narrow base
A wide base support is easier to balance than a narrow base support .
Wide base support will provide you with lower center of gravity, (think how it is easier to stand with two legs compared with standing with one leg)</span>
The most recent Dietary Guidelines for Americans<span>, released in January 2011, recommend that </span>all adults eat at least half their grains as whole grains<span> – that’s at least 3 to 5 servings of whole grains. Even children need 2 to 3 servings or more. Recommendations in Canada’s Food Guide are almost exactly the same. (Not surprising, since the human body changes little from country to country!)
Hope this help </span>
