AVprozaik [17]

Answer:

Pleiotropy.

Explanation:

Pleiotropy may be defined as when the single gene shows the multiple phenotypic traits. The gene is known as the pleiotropic gene and its mutation may affect the several phenotype expression.

The frizzle gene control the multiple phenotype effects like defective feathers, high blood flow, low egg lay rates and high metabolic rates. This is a case of pleiotropy because here a single gene is responsible for the multiple phenotypes.

Thus, the answer is pleiotropy.

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.

Discuss the relationship between Gibbs free energy, redox reactions and cellular respiration in mitochondria.​
Finger [1]

Cellular respiration is a redox process that mainly occurs in mitochondria, whereas Gibbs's free energy refers to the energy in a closed system.

<h3>What is cellular respiration?</h3>

Cellular respiration refers to the oxide reduction reactions (redox) associated with the production of energy in aerobic cells.

Cellular respiration occurs in the cytoplasm (glycolysis) and mitochondria (Krebs cycle and oxidative phosphorylation).

Finally, in thermodynamics, the Gibbs free energy refers to the energy generated in a closed system.
