Birds

 

Birds are amazing winged animals that have very intricate designs. Many birds that are kept as pets prefer to have a "friend', so that it doesn't get lonely while its owner is away. Hummingbirds lay the smallest eggs. Ostriches lay the largest. Penguins are the only birds that swim but don't fly. They are also the only birds that walk upright.

 

Owls can turn their heads almost 360 degrees, but they cannot move their eyes. Birds' eyes take up about 50% of their head. Humans' eyes take up about 5% of our head. Males usually have the prettier coloring, better feather shapes, and more beautiful songs to attract mates.

 

The first bird domesticated by a human being was the goose. Birds eat twice their weight each day. So when people say "you eat like a bird", it usually isn't the truth. Chickens that lay brown eggs have red earlobes. Mockingbirds can imitate naturally-parrots have to be taught to do so. Though mockingbirds can't talk like parrots can learn to, they can mimic many different sounds.  Info Credit

SO MUCH DNA!!!!!!!!!!

Did you know that in your body there is enough DNA to go from the sun to Pluto and back 17 times!

DNA is a code in our bodies that is responsible for how our body operates. It controls how we grow what functions our organs do and how we differ from others.The human cell contains 23 DNA molecules each containing between 500,000 to 2,500,000 nucleotide pairs. When uncoiled these molecules are 5 cm long on average. In our bodies there are 37,000,000,000,000 (trillion) cells. So if you uncoil all of the DNA in your body and lay it end to end the distance it would stretch over would be 200,000,000,000,000 meters long which is enough to complete thee round trip from Pluto to the sun about 17 times. ( the round trip is 12,000,000,000,000  which if you divide the 2 distances would give you 16.6666666666667 round trips)
