Text: Upon entry to the mitochondria, the pyruvate is decarboxylated, producing acetyl CoA. This irreversible reaction traps the acetyl CoA within the mitochondria (the acetyl-CoA can only be transported out of the mitochondrial matrix under conditions of high oxaloacetate via the citrate shuttle, a TCA intermediate that is normally sparse). The carbon dioxide produced by this reaction is nonpolar and small, and can diffuse out of the mitochondria and out of the cell.

Text: A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during meiosis. Homologs have the same genes in the same loci where they provide points along each chromosome which enable a pair of chromosomes to align correctly with each other before separating during meiosis. This is the basis for Mendelian inheritance which characterizes inheritance patterns of genetic material from an organism to its offspring parent developmental cell at the given time and area.

Question: do homologous chromosomes carry information for the same traits?

Answer: yes

Text: The wheel and axle can be viewed as a version of the lever, with a drive force applied tangentially to the perimeter of the wheel and a load force applied to the axle, respectively, that are balanced around the hinge which is the fulcrum. The mechanical advantage of the wheel and axle is the ratio of the distances from the fulcrum to the applied loads, or what is the same thing the ratio of the diameter of the wheel and axle. A major application is in wheeled vehicles, in which the wheel and axle are used to reduce friction of the moving vehicle with the ground. Other examples of devices which use the wheel and axle are capstans, belt drives and gears.

Text: In 1934, the ball was made more pointed at the ends. The creation of the pointed football is generally credited to Shorty Ray, at the time a college football official and later the NFL's head of officiating. This made passing the ball easier, as was its intent, but made the drop kick obsolete, as the more pointed ball did not bounce up from the ground reliably. The drop kick was supplanted by the place kick, which cannot be attempted out of a formation generally used as a running or passing set. The drop kick remains in the rules, but is seldom seen, and rarely effective when attempted. In Canadian football the drop kick can be taken from any point on the field, unlike placekicks which must be attempted behind the line of scrimmage.
