The theory of relativity was formulated by Albert Einstein in the early 20th century. It consists of two parts: special relativity, introduced in 1905, which addresses the physics of moving bodies and the constancy of the speed of light, and general relativity, published in 1915, which describes gravity as the curvature of spacetime caused by mass. Einstein's groundbreaking work fundamentally altered our understanding of space, time, and gravity.

False. Charles Darwin developed the theory of natural selection in the 19th century, but he did not have a genetic explanation for inheritance as it was not understood at the time. The principles of genetics were later established by Gregor Mendel, whose work on inheritance patterns was published around the same time but remained largely unrecognized until the early 20th century. Thus, while Darwin's theory of natural selection focused on variation and adaptation, it did not include a genetic framework.

Revivalism swept across the United Staes in the early 19th century. Revival was a religious gathering that relied on emotional sermons to awaken religious feelings which become popular during the early 19th century.

John Dalton formulated his atomic theory in the early 19th century, around 1803. This theory proposed that all matter is made up of tiny indivisible particles called atoms.

Developing the cell theory took time because early microscopes were limited in their capabilities and resolution. It required advancements in microscope technology and techniques to observe and understand the structure of cells. Additionally, multiple scientists had to contribute different pieces of evidence before the comprehensive cell theory was formulated in the 19th century.
Atomic theory began to develop in the early 19th century with scientists like John Dalton, and continued to evolve through contributions from scientists like Niels Bohr and Ernest Rutherford. The theory of relativity was introduced by Albert Einstein in the early 20th century, with his Special Theory of Relativity published in 1905 and General Theory of Relativity in 1915.
Both the Special (first) and General (later) theories of relativity were developed by Albert Einstein. Einstein expressed his indebtedness to the work of Lorentz in developing relativity, but it is still largely Einstein's own work.
The rules were worked out in the middle years of the nineteenth century by an Austrian monk named Gregor Mendel, who devised them after conducting an extensive series of experiments on garden peas.
