Context: Death from laughter is a rare form of death, usually resulting from cardiac arrest or asphyxiation, caused by a fit of laughter. Instances of death by laughter have been recorded from the times of ancient Greece to the modern day.
 Question: can you have a heart attack from laughing Context: Flat breads rarely appear in Greek cuisine; the Greek word pita means ``pastry''. Various cakes and pastries are pitas, such as spanakopita (spinach pie) and karydopita (walnut cake). Traditional breads in Greek cuisine are leavened loaves, such as the round καρβέλι karvéli or the oblong φραντζόλα frantzóla. The full name of the flat bread known in English as pita bread is aravikē pita (lit. 'Arabic pastry'), though it is also called simply ``pita''. In Greece, pita bread is almost exclusively used as a component of pita-souvlaki sandwich consisting of souvlaki or gyros with tzatziki, tomatoes, onions, french fries, and condiments stuffed into a pita bread pocket.
 Question: is flat bread the same as pita bread Context: In mathematics and vector algebra, the cross product or vector product (occasionally directed area product to emphasize the geometric significance) is a binary operation on two vectors in three-dimensional space ( R 3 ) (\displaystyle \left(\mathbb (R) ^(3)\right)) and is denoted by the symbol × (\displaystyle \times ) . Given two linearly independent vectors a (\displaystyle \mathbf (a) ) and b (\displaystyle \mathbf (b) ) , the cross product, a × b (\displaystyle \mathbf (a) \times \mathbf (b) ) , is a vector that is perpendicular to both a (\displaystyle \mathbf (a) ) and b (\displaystyle \mathbf (b) ) and thus normal to the plane containing them. It has many applications in mathematics, physics, engineering, and computer programming. It should not be confused with dot product (projection product).
 Question: is the cross product of two normalized vectors normalized Context: The Lieutenant Governor is an ex officio member of several statutory bodies. These include the Legislative Budget Board, the Legislative Council, the Legislative Audit Committee, the Legislative Board and Legislative Council, which have considerable sway over state programs, the budget and policy. The Lieutenant Governor is also a member of the Legislative Redistricting Board (together with the Speaker of the House, Attorney General, Comptroller, and Land Commissioner), which is charged with adopting a redistricting plan for the Texas House of Representatives, Texas Senate, or U.S. House of Representatives after the decennial census if the Legislature fails to do so.

The nucleotide sequence recognized for cleavage by a restriction enzyme is called the restriction site. Typically, a restriction site will be a palindromic sequence about four to six nucleotides long. Most restriction endonucleases cleave the DNA strand unevenly, leaving complementary single-stranded ends. These ends can reconnect through hybridization and are termed ``sticky ends''. Once paired, the phosphodiester bonds of the fragments can be joined by DNA ligase. There are hundreds of restriction endonucleases known, each attacking a different restriction site. The DNA fragments cleaved by the same endonuclease can be joined together regardless of the origin of the DNA. Such DNA is called recombinant DNA; DNA formed by the joining of genes into new combinations. Restriction endonucleases (restriction enzymes) are divided into three categories, Type I, Type II, and Type III, according to their mechanism of action. These enzymes are often used in genetic engineering to make recombinant DNA for introduction into bacterial, plant, or animal cells, as well as in synthetic biology.
