Answer:
Glass
Explanation:
Copper is a good conductor of electricity and this is why it is used in electrical equipment to transmit electrons with the least resistance. Cable conductors are made of copper and used to transmit data. Copper is now being replaced by optic fiber that is made of glass. Instead of using electrons, fiber optic transmits data using photons – which transmits more data rate than copper.
<span>Tetraphenylcyclopentadienone has five conjugated aromatic rings. Its structure suggests that it is highly conjugated. With this structure, it absorbs the energy from wavelengths of colors other than violet and reflects the energy from violet wavelengths.</span>
Comparing DNA
Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor. Look at the diagram in Figure 9.3
