How do scientists decide when to change or modify their understanding of a particular topic?​
Natali5045456 [20]

Answer:

they carry out experiments to understand it

Explanation:

Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).

Escribe lo que piensa de la siguiente suposición si es cierta o no: " Todas las semillas de una fruta sobrevivirán, se convertir
MissTica

Answer:

Esta suposición no es realista, muchas de las semillas no llegarán a la etapa adulta y por lo tanto no podrán generar nueva progenie

Explanation:

Acorde a la teoría de la evolución por selección natural planteada por Darwin, solamente aquellos organismos que se encuentren mejor adaptados al ambiente en el que viven podrán sobrevivir y de este modo perpetuar sus genes en la progenie. Este es un principio que aplica a todos los tipos de organismos vivientes (es decir, plantas, animales, bacterias, etc). Darwin definió a este proceso evolutivo como 'descendencia con modificación', donde aquellos organismos que se encuentren mejor adaptados a su ambiente transmitirán sus rasgos a la descendencia, mientras que aquellos que no se encuentren suficientemente adaptados no podrán sobrevivir.
