Best Answer: Hazardous food (raw meat, eggs, etc) can only be in the Temperature Danger Zone (TDZ) for a total of 4 hours! The TDZ if between 40-140 degrees.After this 4 hour time period, the meat will start to develop bacteria which leads to all sorts of nasty stuff.est Answer: Hazardous food (raw meat, eggs, etc) can only be in the Temperature Danger Zone (TDZ) for a total of 4 hours!

Postaxial polydactyly, or an extra pinky finger, is the second most common malformation of the hand, occurring in approximately one in 3,000 births.
The Y chromosome is dramatically smaller than the X chromosome and has already lost nearly all of the 640 genes it once shared with the X chromosome. An extreme example of genes disappearing from the Y chromosome can be found in the Ryukyu spiny rat, which is indigenous to a single island in Japan. In this species, the Y chromosome has disappeared completely, with many Y-linked genes moving to either the X chromosome or non-sex chromosomes (autosomes).
