Demostrar que los seres vivos surgen de los seres vivos es la principal razón para realizar experimentos.
Explicación:
El experimento de Pasteur en "Frascos cuello de cisne" ayudó a refutar la teoría de la generación espontánea porque Pasteur usó caldo de carne hervido en matraces cuello de cisne para mostrar que los microbios en el aire son responsables de causar la contaminación de los alimentos. Al mostrar que las criaturas vivientes surgen de la materia viva en su experimento, la teoría de la generación espontánea resulta inválida.
Explanation: C and D are jokes/ complete lies. B is wrong because Darwin did observe that animals and plants adapted (evolved) to suit their environments.
Amongst the several types of viral hepatitis, it is hepatitis A that can spread through the fecal-oral route.
Usually, a person can acquire hepatitis A if he/she ingests contaminated food or water, further it can also spread through direct contact with the infected person.
due to its transmission through the fecal-oral route, lack of good sanitation practices and hygiene are the major causes for its spread.
