Explanation:
Water is essential for the normal functioning of the organ systems in the body. Dehydration occurs when the water we take in is less than the water we lose. Water is lost fr the body through sweating, breathing, urination and defecation. Disease conditions like diarrhea and vomiting also cause loss of water.
When the body senses dehydration, there is a thirst signal to tell us to drink more water. The body then proceeds to the water leaving through the kidneys thereby conserving water in the body. This explains the concentrated and colored urine during dehydration.

Answer:
All of the options are true for a MRSA infection.
Explanation:
<em>Staphylococcus aureus</em> is one of the most frequent pathogens causing hospital and community infections. <em>S. aureus</em> can become very easy methicillin resistant (called MRSA isolates) and others beta-lactam antibiotics (are the ones widely used to treat infections) and usually can be resistant to other class of antibiotics, become a very strong bacteria making treatment options very limited. MRSA isolates can rapidly transfer the methicillin resistance to other species of S<em>taphylococcus</em> and some other bacteria. Also <em>S. aureus</em> can acquire other antibiotic resistant genes making a deadly bacterium for its strong resistance. It is in search how the bacterium acquire this antibiotics resistance ( and other virulence factors genes) and the mechanism involve to develop new drugs to treat MRSA infections with the hope that can´t develop resistance to this new drugs.
It permits calcium to leave the sarcoplasmic reticulum and enter the cytosol. During muscle contraction, the binding of acetylcholine initiates an excitatory impulse, which is transmitted to the deep of the muscle via T tubules. T tubules are the invaginations of cell membranes of muscle cells (sarcolemma). When the action potential travel down the t-tubules, they change shape and allow the calcium ions to enter into the sarcoplasm from the sarcoplasmic reticulum.
