In subtropical growing regions (such as Brazil, which grows the most oranges in the world), temperatures are never cold enough to break down the chlorophyll in the fruit's skin, so it may still be yellow or green even when ripe. However, because American consumers are baffled by such a phenomenon, imported oranges are treated with ethylene gas to remove the chlorophyll and turn them orange.

Although the now-retro rainbow design is undoubtedly Apple's most well-known, the very first Apple logo depicted Sir Isaac Newton seated under a tree with an apple ready to fall on his head. The Newton logo was created by Apple's lesser-known creator Ronald Wayne and was only used briefly in 1976. Its high degree of detail didn't show up well when scaled down and put on a device.
If you ate a Macintosh apple and planted the seed, the tree that grew would produce apples that didn't look or taste like Macintoshes. Instead of planting seeds, growers graft a cutting from a genetically desirable tree onto an existing branch or sapling (called the "rootstock"), resulting in apples that are genetically identical to those on the tree from which it was cut. If you look closely at the tree in the photo, you can see that there are several different types of apples on the various branches, all of which are grafted onto the same rootstock tree.
You probably don’t know this, but the calendar that we use today was invented by ancient Egyptians. Yes, ladies and gentlemen, the first calendar known to humankind was invented in Egypt. In fact, it is the year 6264 in the Egyptian calendar.
The ancient Egyptians used the 12-month calendar like we do today. However, each month was always 30 days which meant that their years were only 360 days in total causing the years to fall out of sync with the seasons. So to make up for the lost time, they held a 5-day festival at the end of each year.
