Sort the terms into the correct category

Which statement best describes the difference between a scientific theory and a scientific law?

Jean-Baptiste Lamarck was a French naturalist who proposed the idea that modern-day organisms developed new characteristics through a process known as the inheritance of acquired traits. As more evidence became available, this theory was eventually replaced by Charles Darwin’s theory of evolution. This modification of scientific knowledge illustrates that

Which of these are not part of the original Cell Theory? (choose all that apply)

Early elements of the cell theory followed the development of Hooke’s light microscope. What does this relationship suggest about the evolution of the cell theory since Hooke?

Virchow’s observations of cells multiplying help to disprove which misconception of cells?

Which of the following is an additional tenet of the modern cell theory?

Large numbers of ribosomes are present in cells that specialize in producing which of the following molecules?
