In the early days of germ theory, contagious diseases were thought to be caused by fungi or bacteria. in the 1890s, dmitri ivanovski filtered extracts from diseased tobacco plants and discovered that the disease could be transmitted to new plants through the filtrate. he concluded that the disease was caused by particles smaller than bacteria: the tobacco mosaic virus. which best explains how ivanovski’s work led to a change in the germ theory?
he tried to promote his hypothesis as a law.
he used a new experimental method to test his hypothesis.
he used a more powerful bacterial strain than other scientists had.
he obtained results that confirmed what other scientists were thinking.

Correct B). He used a new experimental method to test his hypothesis.

The germ theory of the disease is the theory that states that the disease in humans and plants are caused by the microorganisms. Before the 19th century, it was believed that communicable disease is caused by bacteria and fungi. Viruses were not discovered at that time.

The work of Ivanovski on the tobacco plant was responsible for the discovery of viruses.

Hence, the correct answer would be option B.

mientras se trata la anorexia o la bulimia, es importante buscar ayuda antes que nada. un profesional de la salud mental será el más útil para aquellos que sufren anorexia o bulimia. este es un buen lugar para comenzar, sin embargo, ver a otros profesionales como dietistas registrados, especialistas médicos y dentistas podría ayudar a alguien a recuperarse de un trastorno alimentario. después de la ayuda profesional, o si la ayuda profesional no es una opción, alguien que se recupere de la anorexia o la bulimia debe rodearse de compañeros de apoyo, padres u otros miembros de la familia que también estén comprometidos con el proceso de recuperación.

hope this you! : )
