What is required before a hypothesis advances to the status of a scientific theory ?
Vesna [10]
<span>The hypothesis has to survive all attacks on it and continue to provide the best known explanation of the known data. In the scientific method, there are several steps towards the creation of a hypothesis and eventually a theory.
 1. Gather data. 
 2. Construct a hypothesis that explains the data. This hypothesis should be capable of being disproved and should be capable of making predictions.
 3. Gather more data. DO NOT cherry pick only that data which supports the hypothesis . If data is uncovered that contradicts the hypothesis , revise or replace the hypothesis.
 4. After the hypothesis has survived all attacks on it and is the best known explanation of the data, then it becomes a theory.
 5. Note, data collection continues after the hypothesis became a theory and if new data is discovered that is in conflict with the theory, then the theory is modified, or discarded in favor of a new hypothesis or theory.</span>

En los seres vivos acuaticos el oxigeno es tomado del __________ y penetra a la celula por el fenomeno de ___________
andrezito [222]

Answer:

En los seres vivos acuáticos el oxigeno es tomado del <u><em>agua</em></u> y penetra a la célula por el fenómeno de <em><u>respiración branquial.</u></em>

Explanation:

La respiración es el proceso mediante el cual los seres vivos obtienen oxígeno.  Es decir, la respiración implica el reemplazo del dióxido de carbono en los pulmones por oxígeno del aire, y puede ser pulmonar, branquial, traqueal o cutánea.

La respiración branquial es un tipo de respiración propia de la mayoría de los animales acuáticos y se lleva a cabo en las branquias, unas estructuras con forma de láminas que contienen vasos sanguíneos. Los animales acuáticos dispone de estos órganos que permiten absorber el oxígeno que se encuentra en el agua y eliminar el dióxido de carbono.

El agua que entra por la boca y circula por las branquias, donde el oxígeno es absorbido, pasa a la sangre y es transportado a todo el cuerpo donde se produce una respiración celular.

Es decir, <em><u>en los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.</u></em>

A child has a blood type of O. Can the mother of that child have a blood type of AB?
adell [148]

Explanation:

Yes they can. An AB parent can indeed sometimes have an O child. But it is by no means common. In fact it would be fair to say that it is exceedingly rare.

The one exception is in certain Asian groups. Some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child.
