Which statement is supported by the cladogram?
fgiga [73]

A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.

In this set of examples the answer is:

D) The lamprey does not have a vertical column

Lampreys have a notochord that remains throughout life, but they have primitive vertebrae made of cartilage. Lampreys have vertebral arches, but nothing resembling the vertebral bodies found in all higher vertebrates. Even the arches are discontinuous, consisting of separate pieces of arch-shaped cartilage around the spinal cord in most parts of the body, changing to long strips of cartilage above and below in the tail region.

Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA,
Elza [17]

Answer:

The correct answer will be- 21, 29, 29

Explanation:

In a DNA sequence, the nucleotide base pairs on one strand of DNA are  complementary to the base pair on other strand of DNA.

According to the Chargaff rule, Adenine binds Thymine and Cytosine binds Guanosine which shows that the amount of A will equal T and the amount of G will equal C.

Therefore, when the amount of C is 21%, then the amount of G will be 21%.

To find amount of AT= 100-GC

                              AT= 100-42

                                AT= 58%

So, AT/2= 29% each

Thus, A=T= 29%

          G=C=21%
