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.

HELP!! DNA was isolated from water samples taken from six different sites. This gel

VladimirAG [237]

After running DNA in a gel, bands of different sizes and species might appear. Scientists know silver carp are at North Shore site 1 because one of the bands in lane 1 matches a band in the positive control (Option C).

When DNA was isolated and run in a gel, many bands migrated to different points.

These bands were the different-sized fragments of DNA samples from different species from the six sites.

Researchers wanted to figure out where the silver carp is.

To do it, they needed to identify the bands on the gel that belonged to the silver carp DNA, so they included negative and positive controls to make comparisons.

<h3>Positive and negative Controls</h3>

Negative and positive controls guarantee the interpretations of the results.

The positive control shows the band sizes that belong to the silver carp DNA.

Any band in the sampling sites that matches one of the positive control bands indicates that the species is present at that site.

The negative control is the opposite. It is the absence of the species' DNA.

<h3>Results interpretation</h3>

As we can see, there are four sites where the bands match one of the bands of the positive control. These are,

North shore site 1
Chicago site 1
Calumet site 1
Calumet site 2

This means that at these four sites, the silver carp is present.

So scientists know silver carp are at North Shore site 1 because one of the bands in lane 1 matches a band in the positive control (Option C).

By looking at the lane of the North Shore site 1, we can also see another band (Thinner and grey). But this band does not match either of the positive control bands. This result suggests that the grey band belongs to another species' DNA.

This is a volume of space that is empty of matter. Example: Sound cannot travel here.

aleksandr82 [10.1K]

Answer:

Vacuum

Explanation:

A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.

For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.
