1. Species vary over time
2. The fossil and the living species will have some similarities and some differences
The <span> Nitrogenous bases </span><span> of dna form the rungs, linking the Nucleotides strands together through P</span>hosphodiester bonds . Each rung<span> is made up of two bases that </span>link together and because of their chemical nature, A (<span>adenine ) </span><span>will only </span>link with T (thymine) and G (<span>guanine ) </span><span> will only </span>link with C (<span>cytosine)</span><span>. </span>Nucleotides are joined together<span> to </span>form<span> two long </span>strands <span>that spiral to build a structure called a double helix. If it looks like a ladder, the phosphate and sugar molecules would be the </span>sides<span>, while the bases would be the </span>rungs.

Answer:
1. DNA
2. RNA
3. Nucleus
4. Nuclear membrane
5. Nuclear pore
6. Nucleolus
7. Chromatin
Explanation:
DNA is present in nearly all living organisms. It has the capacity to replicate itself and also the capacity to be transcribed into RNA. The latter contains the genetic codes that are usually translated during protein synthesis.
The nucleus is the most prominent, membrane-bound (nuclear membrane) organelle in the eukaryotic cell. The nuclear membrane has a special pore, the nuclear pore, through which molecules can be transported between the nucleus and the cytoplasm.
Within the nucleus is the nucleolus, a spherical structure whose primary function is to make ribosomal subunits. The genetic materials in the nucleus are in the form of chromatin, a decondensed protein-DNA complex.
