Stolb23 [73]

Answer:

1. Nutrientes:

- alimento  

- oxígeno (O2)

2. Productos de la nutrición animal:

- residuos orgánicos  

- dióxido de carbono (CO2)

Explanation:

Los alimentos son sustancias químicas que los animales ingieren a fin de que el organismo transforme dichos compuestos en nutrientes los cuales son requieridos para la generación, el crecimiento y la reconstrucción de células y tejidos.

El oxígeno (O2) es un nutriente escencial para la vida el cual se absorbe mediante el proceso de respiración. Este proceso posibilita la absorción de otros nutrientes obtenidos a través de la alimentación.

Los residuos orgánicos representan productos de la nutrición animal los cuales se descomponen naturalmente para formar parte de la materia orgánica. En animales, los desechos órganicos son eliminados a través de los excrementos o en la orina.  

El dióxido de Carbono (CO2) es un producto de la respiración. En animales, la respiración celular consume oxígeno y compuestos orgánicos con el objetivo de producir energía en forma de ATP. Como concecuencia del proceso de respiración, los animales liberan CO2 al medio ambiente.

A lab assistant needs to mix up the following reaction to prepare DNA for an experiment:_________.
lara31 [8.8K]

Answer:

Explanation:

The total solution formed after mixing the components will be

20 μl + 20 μl + 40 μl + 120 μl = 200 μl

The smallest size tube that will hold the entire reaction is:

Firstly convert 200μl to ml

1000 μl = 1 ml

200 μl = X

X = 200 x 1/1000

X = 0.2 ml

The smallest size tube (from the options provided in the question) is 0.25 ml.

The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.

The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl
