Answer:
There is a term "atmospheric circulation". It is when the air throughout the globe moves around. When the sun heats air near the equator more, and less at the poles. So the equator is warmer. The warm air near the equator moves either towards the south or the north, toward the poles. The warm air also rises up, and the cold air sinks. This is convection, but at a global scale. THis is also the cause of wind.
Answer:
<h3>White sugar is polished and refined sugar. It has a high glyciemic index (Glycemic index)</h3><h3>GI represents the total rise in your blood sugar level following consumption of the food. White sugar probably has a GI of around 96 which is pretty close to the highest (100 of pure glucose). </h3>
<h3>Hence it is unhealthy because the body is unable to burn off this sudden spike in glucose levels.</h3>

The smooth, but steady, increase in muscular tension produced by increasing the number of active motor units is called a recruitment.
Muscle tension is the force produced when a muscle contracts (or when sarcomeres shorten). The two primary forms of skeletal muscle contractions, isotonic contractions and isometric contractions, are produced when a muscle contracts against a load that is not moving.
- A load is transported as the length of the muscle varies during isotonic contractions, in which the tension in the muscle remains constant (shortens). Concentric and eccentric contractions are the two varieties of isotonic contractions.
- When a muscle contracts isometrically, the angle of a skeletal joint remains the same while tension is produced in the muscle. Sarcomeres shorten and muscles tense up during isometric contractions, but the load is not moved since the force generated is insufficient to overcome the resistance provided by the load.
