What makes human dna different from oak tree or frog dna?

Nucleotide arrangement

Explanation:

There are obvious differences between humans, oak trees and frogs, but at the molecular level- the cells of all eukaryotes including plants and animals contains DNA in the same shape (double-helical).

All DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits (A, G, C, T). Each of these chains is known as DNA strand. The difference between species lies in the arrangement of the nucleotide bases in the DNA of respective organisms.

The sequence of nucleotides determines which proteins will be synthesized. The way the nucleotides (Adenine, Guanine, Cytosine and Thymine) are arranged determines the information they encode, this information ultimately determines whether the organism will produce scales(frogs), leaves (oak plant) or legs (humans).

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
