Final answer:
Antebellum technological innovations, such as textile machinery, steam engine, telegraph, and interchangeable parts, resulted in increased industrial production and efficiency, reduced reliance on manual labor, and improved communication and transportation.
Step-by-step explanation:
Antebellum technological innovations, such as textile machinery, steam engine, telegraph, and interchangeable parts, had several significant results. First, they led to increased industrial production and efficiency. For example, the textile machinery allowed for mass production of fabric at a better price and quality. Second, these innovations reduced reliance on manual labor by introducing machines that could perform tasks more efficiently than humans. Finally, they improved communication and transportation, with inventions like the telegraph enabling faster communication and steam-powered transportation revolutionizing travel and trade.
