Answer:
Skeletal muscle stores glycogen because it is a heavy consumer of energy.
Explanation:
Skeletal fiber contractions are based on different physiological and biochemical phenomena that happen in every cell and that need an amount of energy to occur. During muscle contraction, <em>myosin binds to the uncovered actin-binding sites, producing littles power strokes that, continuously, lead to muscle contraction</em>. To make this process possible, the muscle needs energy.
Glycogen is a very important energetic reserve polysaccharide for animals. It is stored in the liver and muscles, and when the organism needs energy it degrades glycogen into glucose, which is an available form for the metabolism. In the liver,<em> glycogen</em> is used to maintain constant levels of <em>blood glucose</em>. While in muscles, glycogen plays an important role in the glucose storage as a source of energy, needed and used only for contraction.
During muscle contraction, ATP molecules obtained from glucose are split to ADP and inorganic phosphate.

Pampas and Patagonia
The Pampas are prolific South American marshes that comprise more than 750,000 km2 and combine the Argentine territories of Buenos Aires, La Pampa, Santa Fe, Entre Ríos and Cordoba. The vast fields are a common region, suspended only by the low Ventana and Tandil hills, near Bahia Blanca and Tandil Argentina, with an elevation of 1,300 m (4,265 ft) and 500 m (1,640 ft), sequentially.
Patagonia is a sparsely populated area at the southerly end of South America, administered by Argentina and Chile. The district encompasses the southerly segment of the Andes hills and the sands, pampas, and meadows to the east. Patagonia is one of the rare areas with shores on three oceans, with the Pacific Ocean to the westward, the Atlantic Ocean to the east, and the Southern Ocean to the South land.
Answer:
B. similar to the cells just treated with the dye - 0% dead
Explanation:
According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.
Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.
A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead

During the relative refractory period of an action potential, a larger than normal stimulus is needed to cause another action potential. This is due to the fact that t</span>he voltage gated potassium ion channels remain open long enough to hyperpolarize the axon membrane.
