sleep the person is in deep sleep state.
<span>This is avoidance conditioning. Brenda has been able to successfully link the over-the-counter heartburn medicine to an avoidance of discomfort. By taking the pill, she has received a negative reinforcement due to the removal of the indigestion. The reinforcement will likely lead to Brenda continuing to take the medicine until she habituates to it and does not receive the same benefit(s).</span>
Answer:
The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.
The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.
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.
The answer is <span>reuptake.
Reuptake is a term used when a neurotransmitter is taken back by the axon after being used. By doing reuptake, the synapse will be cleaned out of the neurotransmitter, making it stop giving the signal.
Some drug target reuptake mechanism like serotonin reuptake inhibitor that used for depression. This drug can increase serotonin by inhibiting the reuptake mechanism.</span>
