Answer:

Por qué algunos fosiles son similares a especies actuales
Blizzard [7]

Answer:

Explanation:

La evidencia de un antepasado común en los seres vivos, que han encontrado durante décadas científicos que trabajan en numerosos campos, demuestra la descendencia común de estos seres, que la vida en la Tierra se desarrolló a partir de un último antepasado universal, que la evolución existe y que puede demostrar los procesos naturales que han dado como resultado la biodiversidad de la vida en la Tierra. Esta evidencia apoya la síntesis evolutiva moderna, la actual teoría científica que explica cómo y por qué cambia la vida a lo largo del tiempo. Los biólogos evolucionistas han documentado evidencias de antepasados comunes realizando predicciones verificables, probando hipótesis y desarrollando teorías que ilustran y describen sus causas.

Real Question:
telo118 [61]

Answer:

When you are hungry your brain signals your digestive system to prepare for food. This leads to stomach growling. Your brain does this because it knows that you are hungry, and consequently the brain signals the digestive muscles  to contract. There is also, usually, some gas in the intestines and stomach. The noises come out when the mixture of the gas and fluid, digestive juices, squirt through a opening that separates the stomach and small intestine.

Sometimes the noises happen because of an excessive amount of gas in the small intestine.
