A team of students is performing an experiment to determine how the speed of a reaction between HCl and Na2CO3 changes with temperature. The aspect of the  experiment that does not have to be kept constant would be the initial concentrations of the reactants. Hope this helps. Have a nice day.

Una parte de la radiación
diamong [38]

La troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

En la capa de la troposfera, que es la capa más baja de la atmósfera, hay vapor de agua, dióxido de carbono, metano y algunos otros gases que son responsables de la absorción de la radiación infrarroja. Parte de la radiación infrarroja se escapa al espacio, pero una parte es detenida y absorbida por los gases de efecto invernadero presentes en la atmósfera.

Esta absorción de radiación infrarroja por los gases de efecto invernadero contribuye a un aumento de la temperatura de la superficie de la tierra y de la atmósfera. Entonces, podemos concluir que la troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

Dimas [21]

Answer: B.) More research is needed to reach a conclusion, including related variables

Explanation:

As it is evident that oxygen is necessary element for living beings. It is required for the process of respiration, in which the food particles are broken down in the presence of oxygen into simpler substances.

Applying this knowledge to the given study suggests that all organisms require oxygen which can be less or more depending upon their habitat either in the shallow waters or in the depths. This conclusion is invalid and requires more explanatory approach which can be achieved by more research so as to derive a valid conclusion in which the two variables oxygen and relative habitats can be compared.

Which of these is a piece of evidence supporting the theory of evolution? The Glyptodon exists in some parts of the world. Emu a
raketka [301]

Answer:

The glyptodon is found to be similar to the armadillo.

Explanation:

A piece of evidence that supports the theory of evolution is that the glyptodon is found to be similar to the armadillo. Glyptodons and armadillos have many things in common, expect that glyptodons are much larger (the size of a Volkswagen beetle!) than an armadillo. The change from the prehistoric glyptodon to our modern day armadillo helps support that there is evolution because they still have many things in common. They are genetically related.
