Sally was analyzing samples of dna. she had dna samples from bacteria, a whale shark, a bald eagle, and a human. just by looking at the structure and components of the dna, what could sally conclude? a) the eagle and shark would have very similar dna b) the dna of the human would have a more complex physical structure than the rest c) only the dna of the bacteria would be coiled into a double helix, so she could identify it d) all dna is made of the same components so she would see no difference between the samples

Option D is correct.

D) all DNA is made of the same components so she would see no difference between the samples

DNA is hereditary material and it is made up of the same components in all organisms from bacteria to a whale shark so by just looking at that Sally cannot differentiate between the DNA of different organisms.

Animal

Explanation:

The fact that the seed is sweet and fleshy means it attracts animals who ingest it due to its palatability. The animals get to diperse the plant seeds. The acidic environment of the digestive tract of the animals helps soften the seed coat. When the seed is finally excreted by the animal, is can easily germinate.
