Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción
Likurg_2 [28]

Sobre la pregunta:

Cucigrama. Pregunta 1 vertical. Absorbe nutrientes por medio de micro vellosidades que recubren y aumentan la superficie de absorción

Answer:

Intestino delgado

Explanation:

El intestino delgado es el organi mas largo del tubo digestivo, pudiendo medir 7 metros de longitud y 3 cm de diametro. Se caracteriza por estar sumamente plegado sobre si mismo. La primera porcion, llamada duodeno, recibe secresiones de glándulas biliar y pancreática, y las mezcla con enzimas digestivas. Esta mezcla se encarga de degradar la comida y transformarla en sustancias solubles, como amino ácidos.

Es en el intestino delgado donde ocurre la absorción de nutrientes.  Las paredes intestinales estas cubiertas por microvellosidades que aumentan la superficie de absorción.  

Las microvellosidades son células que componene el epitelio columnar, y que extienden proyecciones hacia el lumen del organo.

sasho [114]

Mendel was able to attribute the variation observed in the offspring of his experiment to the controlled fertilization process.

Mendel was able to control pollination and, thus, the fertilization process in the pea plants used for his experiment.

Mendel was able to effectively predict the outcome with self-pollination or cross-pollination with different results coming from each. Thus, he logically concluded that the variation observed in the offspring of his crosses is due to the fact that he controlled the fertilization process.
