Final answer:
The cell theory has a) advanced medical science, b) enabled genetic engineering and biotechnology, and c) improved forensic science through DNA analysis.
Step-by-step explanation:
The cell theory has significantly impacted the modern-day world by enhancing various scientific and practical applications. Here are three specific examples:
It has advanced medical science, leading to breakthroughs in understanding and treating diseases. This is because cell theory underpins knowledge about how cells operate within the body, how they malfunction in disease, and how they can be manipulated for treatment.
It has enabled genetic engineering and the development of biotechnology. The cell theory's framework allows for the manipulation of cells and their genetic material, paving the way for advancements in drug production, agricultural improvements, and even potential gene therapies for genetic disorders.
It has improved forensic science by enabling DNA analysis for solving crimes. Understanding that each cell contains DNA unique to an individual guides forensic experts to use cellular material left at crime scenes to identify perpetrators.
The cell theory asserts that all living things are made up of cells, which are the smallest units of structure and function in organisms. It also declares that new cells are produced from existing cells. It does not, however, have any relevance to transportation systems, an area impacted by many other types of technological advancements unrelated to biology or cell theory.
