Billy Bell How does gene duplication occur and how might it play a role in evolution? Gene duplication can provide new genetic material for mutation, drift and selection to act upon, the result of which is specialized or novel genetic functions. Without gene duplication, the flexibility of genomes or species in adapting to changing environments would be … Read more
How are biochemical sedimentary rocks made? Biochemical sedimentary rocks consist of the shells and bodies of underwater organisms. Organisms extract chemical components from water and use them to build shells and other body parts. Ingredients include aragonite, a mineral similar to and commonly substituted for calcite and silica. How are Quizlet biochemical sedimentary rocks made? … Read more
How does the surface tension of water affect the amount of water droplets a coin can hold? You should find that regular tap water produces a much larger standing water drop on top of the coin than in soapy water. This is because regular tap water has a higher surface tension, so the surface is … Read more
What is the origin and structure of the solar system? formation – composition. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shock wave of a nearby exploding star called a supernova. When this dust cloud collapsed, it formed … Read more
What is the property of sound waves related to volume? The amplitude of a sound wave determines the relative loudness of a sound. In music, the loudness of a note is called its dynamic level. In physics, we measure the amplitude of sound waves in decibels (dB), which does not correspond to dynamic levels. What … Read more
