Why does earth turn so slowly?​

Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation. Atomic clocks show that a modern-day is longer by about 1.7 milliseconds than a century ago, slowly increasing the rate at which UTC is adjusted by leap seconds.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
