Rosalind Franklin is best known for her work on the X-ray diffraction images of DNA which led to the discovery of the DNA double helix.

He is best known for his work as a naturalist, where he observed and documented plants and animals on the Galapagos Islands, and for his theory of evolution through natural selection.

Rosalind Franklin used x-ray crystallography to study the structure of dna molecules.

Robert Hooke discovered that living cells are made up of smaller compartments that he called “cellular sacs”. He also observed that cork is made up of small, hollow cells.

William Harvey is most remembered for being the first physician to describe the circulation of blood in the body.

Carolus Linnaeus classified organisms based on their similarities and differences. He placed them in groups and gave them names based on their characteristics.

Each of these men were important figures in their respective fields who made significant contributions to our understanding of the world.

The main difference between the theories of Lamarck and Darwin is that Darwin’s theory of evolution by natural selection is widely accepted by the scientific community, while Lamarck’s theory of evolution by acquired characteristics is not.

Robert Hooke discovered that living cells are composed of smaller units he called “corpuscles.” Anton van Leeuwenhoek was the first to see and describe bacteria.

Robert Hooke is credited with discovering cells in 1665. In his microscope observations, Hooke saw tiny compartments that he likened to the cells of a honeycomb. Hooke’s discovery laid the foundation for cell theory.
