Fossils give Scientists look into past life. A dinosaur that mixes together a reptile and a bird helps scientists understand present day reptiles & birds. Animal Ancestry helps Scientists discover what ancestors of present day animals are. example: a dinosaur and an alligator. DNA sequences help with this. By matching together the strands of DNA from these fossils can help scientists match together the strands of DNA sequences For example the gene for a protein found in a horse will overlap in sequence fairly well with the protein gene from a cow but will not match very well with a worm.
The correct answer is segmentation. <span>The annelids also known as segmented worms, are bilaterally symmetrical invertebrate organisms. Their main characteristic is a segmented body. Annelid's body consists of segments that are identical (except the first and the last one), having the same sets of internal organs and external chaetae. Septa separate the segments and enable the annelids to change the shapes of individual segments, which facilitates movement by peristalsis (symmetrical contraction movement).</span>

Explanation:
The big letter is dominant so it is always going to take over the small letter.
Interphase
During interphase, there are three subdivisions: G1, S, and G2. G1 is the growth and development phase. S phase is when the cell duplicates its DNA, so that it can distribute it. In G2, the cell finishes its preparations for mitosis by checking the DNA and ensuring the mitotic proteins are present.
Steps of Mitosis
Prophase
The mitotic spindle begins to form, the nucleolus disappears, the nuclear envelope breaks down and the chromosomes begin to condense.
Metaphase
During metaphase, the chromosomes line up at the metaphase plate in the center of a cell. The chromosomes are connected to the mitotic spindle on either side.
Anaphase
Motor proteins drive this process by pulling the sister chromatids apart towards opposite ends of the cell.
Telophase
The chromosomes begin to de-condense, the nuclear envelope and the nucleolus reappears, and the spindle fibers disappear.
Cytokinesis
After telophase, cytokinesis is the splitting of the cytoplasmic material. It completes cell division.
Hope this helps! :)
