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.
Scientists classify living things in order to organize and make sense of the incredible diversity of life. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA.

Answer:
COMMENSALISM
Explanation:
The interaction of organisms with one another in an ecosystem is called SYMBIOSIS, if it involves two organisms of same or different species. One type of symbiotic relationship is COMMENSALISM, which is a relationship in which one organism benefits while the other neither benefits or gets harmed.
This is the case of the burdock weed and its association with cows, deers or people. The burdock weed benefits from the relationship by getting Its seeds that attaches to the cow's, deer's or human's skin via its hooked-tip burrs, transported to varying locations. Thus, helping to spread the plant. The cow, deer, or human does not benefit fron this relationship neither is it harmed.
Warm water. The higher the temperature or thermal energy, the faster the molecules move.<span />
1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x
2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power.
3) So it doesn't gather dust and fog up the lense? that one should be self explanatory
