Answer:
By counting stars.
Explanation:
During the late eighteenth century, there was an astronomer - William Herschel who tried to estimate the size as well as shape of the galaxy by on the sky. It was the time when astronomers didn't even know that there exist some galaxies outside the milky way. He counted all the stars and created a map of the galaxy.
However, in that attempt he didn't realize that stars he was counting were not clear from his view. With that attempt of incorrect nature, he concluded his work as, the galaxy is disk-shaped, flat and contains sun at the center. Today, when the astronomers got a perfect idea of the vastness of the universe and galaxies, we are in a position to say that Herschel's idea of the galaxies was very tiny and underestimated.
Collagen fiber resembles concrete, or a structure to stick things together. Calcium-containing salts are the most essential minerals to bones, making up around 70% of the grid, including generally calcium phosphate and some measure of calcium carbonate and other calcium or phosphate salts.
While DNA has the ATCG nitrogenous bases, RNA replaces thymine with uracil, making its bases AUCG. So, that means that whenever DNA has adenine, instead of pairing this with thymine, RNA will use uracil instead.
Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures.
