How would you account for the fact that fossils of fish are not present in the older layers of rock?
Mademuasel [1]

Answer:

The fish did not yet exist when the old layers of rocks were deposited. In fact, animals with hard parts did not evolve until about 600 million years ago, which is only about 13% of the 4.5 billion year age of the Earth. Multicellular animals without hard parts left tracks in older sediments, but had no fossilize-able body parts.

Which of the following modifications is least likely to alter the rate at which a DNA fragment moves through a gel during electr
zhuklara [117]

Answer:

A) altering the nucleotide sequence of the DNA fragment

Explanation:

Gel electrophoresis is a technique to separate the DNA fragments on the basis of their charges and size. DNA fragments are made to migrate through a gel in an electric field. DNA has nucleotides and the presence of phosphate groups makes it a negatively charged molecule. In the gel electrophoresis, DNA fragment migrates through the gel toward the positive pole. Also, the gel slows down the large molecules more than the small molecules. Therefore, the DNA fragments are separated by size. However, the sequence of the nucleotide of DNA fragments does not affect the rate of their migration in the gel.
