A partir del concepto de osmorregulación cual es la regulación hídrica y salinas en peces de agua dulce y salada
maks197457 [2]

Answer:

Absorben o excretan agua salada para mantener la homeostasis.

Explicación:

La regulación hídrica y salina en peces de agua dulce y salada se realiza según las condiciones ambientales. Los peces pueden pasar mucha orina muy diluida en la que hay menos solutos o sales, y logran el equilibrio de electrolitos en el cuerpo mediante el transporte activo de sales a través de las branquias. En un ambiente marino hipertónico, los peces de agua salada comienzan a beber agua de mar y mantienen el equilibrio electrolítico mientras excretan el exceso de sales a través de sus branquias y su orina.

Receptor
77julia77 [94]

The correct answers are shorter, longer, and have inverse proportionality and are used in dental radiography.

In the first case vertical angulation is what is used to control the length of any image which is being recorded and it is dictated by the holding device which directs the beam of x-ray perpendicular to both the receptor and teeth and in this case the image which is formed is shorter then the real teeth and it also occurs if the central ray is directed perpendicular to the plane of the receptor rather than to the imaginary bisector.

In the second case, the vertical angulation is flat or if it is too small the image of the teeth will be longer than the actual teeth and it often occurs due to bisecting technique.

Distortion is any kind of change that can occur in both the shape and size of the object and this is inversely proportional to the vertical angulation as when vertical angulation is not correct it creates distortion and also the steep is angulation the smaller the image will be and flat the angulation is the larger or longer the image is and in distortion which comes due to radiograph is mainly used for the teeth and the recommended angulation is +10 degree in which the central ray is directed through the contact of the teeth.

This is also called dental radiography.
