What is the ultimate fate of materials in cells according to the Second Law of Thermodynamics?

• Energy is created

• Energy is conserved

• Energy is destroyed

• Greater order or entropy

What is the theory of evolution?

• A hunch about gene distribution

• An idea that explains several phenomena at once

• A hypothesis about natural selection

• A random guess about species diversity

What is the main evidence for evolution provided by fossils?

• They show that organisms that lived long ago were different from those today

• They prove that all dinosaurs were giant iguanas

• They demonstrate that evolution is a random process

• They reveal that all species have remained unchanged over time

What do homologous structures in different organisms suggest?

• They indicate that the organisms are not related

• They show that the organisms have evolved independently

• They imply that the organisms share a common ancestor

• They prove that the organisms have identical DNA sequences

What is the difference between microevolution and macroevolution?

• Microevolution is observed in animals, while macroevolution is observed in plants

• Microevolution leads to the development of new species, while macroevolution leads to small genetic changes

• Microevolution happens over short time scales, while macroevolution occurs over longer time scales

• Microevolution occurs in small populations, while macroevolution occurs in large populations
