Question

question 1 - 5
anton von leeuwenhoek is attributed to inventing the microscope. the lenses he made enabled him to observe objects he called little animals. later that century, robert hooke connected to cells by adding light to illuminate the objects being viewed. not long after these inventions, cell theory was developed. what does this information suggest about the evolution of cell theory?
validation from scientists other than von leeuwenhoek and hooke was unnecessary
progress on the cell theory was delayed by a lack of scientific discovery
changes made in cell theory were related to technological advancement
the development of cell theory would have occurred without the contributions of von leeuwenhoek and hooke

Explanation:

The invention of the microscope by van Leeuwenhoek and Hooke's contributions were crucial for observing cells, which was essential for the development of Cell Theory. Technological advancements enabled these observations and the progress of the theory. Without them, the development would have been severely hindered.

Answer:

The development of Cell Theory would have occurred without the contributions of van Leeuwenhoek and Hooke is incorrect. Changes made in Cell Theory were related to technological advancement is correct as the microscope was a key technological tool. Progress on the cell theory was delayed by a lack of scientific discovery is incorrect as the microscope enabled discovery. Validation from scientists other than van Leeuwenhoek and Hooke was unnecessary is incorrect as scientific validation is important for theory - building. So the answer is that changes made in Cell Theory were related to technological advancement.
