Answer:
Nervous and Digestive System
Explanation:
The right answer here is option C. They occur in areas with ancient, mineral-poor soil.
An example of that is Amazonia in Brazil, it's one of the biggest forests on earth, and at the same time, we know its soil is poor, but at the same time it has some special materials that can be found there, such as niobium. This forest is, too, rainy almost all the time, and this many trees maintain the temperature of the whole earth stabilized. These kinds of forests can grow in this soil because of the burlap, that's organic materials from its own trees. It's consumed by them, and through this way, it survives and extends its size when humans don't use its resources too much.
Answer:
evidencia de un antepasado común entre grupos de vertebrados (gnatóstomos)
Explanation:
En el estudio comparativo arriba descripto, se encontraron semejanzas que provienen de un antepasados común. Este tipo de evidencia se conoce como homología, es decir, semejanza entre diferentes grupos de organismos causada por un mismo origen evolutivo. Los gnatóstomos (vertebrados con mandíbula) conforman un grupo de organismos el cual incluye peces óseos, peces cartilaginosos, anfibios, reptiles, aves y mamíferos. En este caso, las extremidades del grupo de los gnatóstomos (las cuales tienen como origen común la aleta de un pez primitivo) son similares porque son estructuras homólogas.
The correct answer would be Genetic diversity. Hope this helps.
