 Question: can you have a heart attack from laughing Context: A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea. The first submarine communications cables laid beginning in the 1850s carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fiber technology to carry digital data, which includes telephone, Internet and private data traffic.
 Question: is there an internet cable in the ocean Context: The medullary ascending limb is impermeable to water. Sodium (Na), potassium (K) and chloride (Cl) ions are reabsorbed by active transport. K is passively transported along its concentration gradient through a K leak channel in the apical aspect of the cells, back into the lumen of the ascending limb. This K ``leak'' generates a positive electrochemical potential difference in the lumen. This drives more paracellular reabsorption of Na, as well as other cations such as magnesium (Mg) and importantly calcium Ca due to charge repulsion.
 Question: is the thick ascending limb permeable to water Context: The Texas Rangers are the earliest form of state law enforcement in the United States, first organized by Stephen F. Austin in 1823. The original ranger force consisted of ten men charged with protecting settlers from Indian attacks. Though the rangers of this era are today considered law enforcement officers, they rarely wore badges and were little more than volunteers; the Mexican military was officially in charge of law enforcement in the then-Mexican state of Coahuila y Tejas. The Rangers later served as a paramilitary force on the U.S.-Mexico border and in several armed military conflicts, including the Texas Revolution, the Mexican--American War, and the American Civil War. They continued to fill basic law enforcement and frontier protection roles until the close of the ``wild west'' era. In the early 1900s, they transformed into a criminal investigative agency. The history and legacy of the Texas Rangers has spawned numerous depictions in popular culture. The colloquial image of a Texas Ranger ``always (getting) their man'' has likewise made the Rangers a revered and highly competitive agency within law enforcement, with fewer than 1 in 100 applicants being considered for a single position.
