Which invention of the Scientific Revolution allowed scientists to see tiny details such as blood cells up close?

A.
telescope

B.
microscope

C.
barometer

D.
thermometer

B. Microscope

The correct answer is B. microscope.

To understand how to arrive at this answer, let's break down the question and the given options:

The question asks about an invention of the Scientific Revolution that allowed scientists to see tiny details such as blood cells up close. This implies that the invention should have the capability of magnifying objects to observe small details.

Let's analyze the given options:

A. telescope: A telescope is an optical instrument used to view distant objects by magnifying them. While a telescope is used to observe objects in space, it is not typically used to view tiny details up close.

B. microscope: A microscope is an optical instrument that uses lenses to magnify small objects, allowing for detailed observation of minute structures. Microscopes are commonly used in biology and various scientific fields, making them the most suitable option for observing tiny details such as blood cells.

C. barometer: A barometer is a scientific instrument used to measure atmospheric pressure. It is unrelated to observing tiny details or magnifying objects.

D. thermometer: A thermometer is a device used to measure temperature. It has no relevance to viewing tiny details or magnification.

Based on the analysis, we can conclude that the correct answer is B. microscope.

The invention of the Scientific Revolution that allowed scientists to see tiny details such as blood cells up close is the B. microscope.
