Answer: Fossil records help provide clues to the history of Earth's organisms. They've have given scientists clues needed to determine a present day organism's ancestry by comparing them with fossils. Fossil records also show that life has evolved from simple to complex; for example, fossils deeper into the ground (older ones) are much more simple than the ones at the top (newer ones), again supporting the idea of evolution. Fossils additionally show us how behaviors have evolved, how long individuals lived, and how features evolved over time.
Explanation:
Yeasts is a fungus that is unicellular
Forms of electromagnetic radiation like radio waves, light waves or infrared (heat) waves make characteristic patterns as they travel through space. Each wave has a certain shape and length. The distance between peaks (high points) is called wavelength.
Answer:
Radiation and mutations can cause changes in the DNA but there arent substances. Ribonucleic acids can cause errors if they match with the wrong acid.
