Constitutive skin color is the natural, genetically determined color of the epidermis, uninfluenced by ultraviolet (UV) light or hormone exposure. ... In contrast, facultative skin color results from exposure to UV light and other environmental factors.

hope that helps :)

erica [24]

La respuesta correcta para esta pregunta abierta es la siguiente.

A pesar de que se te olvidó incluir las opciones o incisos para responder a tu pregunta, podemos comentar lo siguiente, basándonos en nuestro conocimiento sobre la materia.

Podemos pensar que la hormona que no produce este niño que sufre de gigantismo es la hormona llamada somatotropina. Esta hormona es muy importante durante el crecimiento y desarrollo del niño en la infancia porque secreta la adenohipófisis, una glándula vital para el correcto y proporcionado desarrollo en la etapa de la niñez.

Entonces, si no hay una secreción correcta de la hormona somatotropina, ésta hace que el niño desarrolle la condición llamada gigantismo.

Entonces podríamos decir lo siguiente.

Un estudiante presenta una condición especial llamada gigantismo su altura es mucho mayor que la de los compañeros de la misma edad y se descarta que la causa sea un problema heredero podemos suponer que este estudiante tiene insuficiente de la hormona de crecimiento o somatotropina. Esta hormona no ingresa a las células en su mecanismo de accion por ser una derivación de aminoácidos.

Kay [80]
<span>The choices for this question are:
</span>-is biologically magnified in ... are recycled in
-is dissipated in ... flow through
-flows through ... are recycled in
-is continuously supplied to ... are continuously removed from
<span>-is recycled in ... flow through</span><span>

On a global scale, energy flows through ecosystems whereas chemical elements are recycle in ecosystems. So the answer is the third option. 

Energy flows through the ecosystem. Most energy comes from sunlight and it is transformed into chemical energy by autotrophs. When they are consumed by heterotrophs the energy is passed on, until it dissipates as heat.  
</span><span>
Chemical elements like carbon and nitrogen, on the other hand, are cycled between biotic and abiotic factors in an ecosystem. This is not possible for energy. These chemical elements come from abiotic factors like the air, light and soil. They are incorporated in the biomass of the photosynthetic organisms and are consumed by other organisms. They are changed back into their inorganic form when the organism dies and are broken down by decomposers and the cycle goes on. So they are constantly being recycled. 

In summary, energy needs a continuous source to be able to maintain and sustain the energy flow in the ecosystem. Chemical elements, on the other hand, are just recycled through processes between abiotic factors and biotic factors. </span>
