By utilizing modern methods of investigation, such as X-ray diffraction and electron microscopy, to explore levels of cellular organization beyond that visible with a light microscope-i.e., the ultra structure of the cell-new concepts of cellular function have been produced. Not only has the study of the molecular organization of the cell probably had the greatest impact upon biologyduring the 20th century but it also has led directly to the convergence of many different scientific disciplines in order to acquire a better understanding of life processes.
The discovery of the structure of DNA by Watson and Crick in 1953 had the greatest impact on Biology during the 20th century. This discovery revolutionized the understanding of genetics and laid the foundation for modern molecular biology and biotechnology.
Biology and psychology are interconnected because they both contribute to understanding human behavior. Biology provides insights into how the brain and body function, influencing behavior and mental processes studied in psychology. For example, neurotransmitters and hormones impact mood and cognition, demonstrating the bridge between biology and psychology.
Biology is relevant in everyday life by helping us understand how our bodies function, how diseases spread, and how organisms interact with each other and their environment. By studying biology, we can make informed decisions about our health, the environment, and the impact of human activities on ecosystems.
Humans are considered to have the greatest impact on the biosphere due to their widespread activities including deforestation, pollution, and climate change. These activities have caused significant changes to ecosystems and biodiversity around the world.
Ecology or conservation biology. These fields focus on understanding the interactions between organisms and their environment, including the impact of human activities like deforestation on ecosystems.
The first microscope was invented in the late 16th century by Zacharias Janssen. Over the years, improvements in lens-making and magnification technology led to the development of compound microscopes in the 17th century. These advancements revolutionized our understanding of the microscopic world and had a profound impact on fields such as biology, medicine, and materials science.
Inventions involving steam power were among those that had the greatest impact during the last half of the 19th century.

The factor that had the greatest impact on union growth at the end of the 19th century was the popularity of social Darwinism.
The Newtonian science exerted its greatest impact of the scientific enlightenment period in the 17th and 18th century.

The expansion of transportation networks, particularly the development of streetcars and railways, had the greatest impact on urban sprawl at the end of the nineteenth century. These systems made it easier for people to commute longer distances to work and live farther away from city centers.
