Why is it important for molecules to able to travel into and out o your body's cells?
lana [763]
Es fundamental que existan moléculas que faciliten el mantenimiento de la homeostasis, el movimiento de alimentos, la regulación de la isotonicidad de la célula mediante la circulación de agua, la entrada de glucosa para evitar que la célula se depobre y la salida de desechos para prevenir acumulaciones en la misma.

Which of the following is most consistent with homeostasis? Select one: a. As blood pressure falls, blood flow to cardiac (heart
inysia [656]

Response:

Las respuestas más adecuadas serían tanto C como E.

Clarificación:

La homeostasis se refiere a la habilidad del cuerpo para conservar un equilibrio estable. En otras palabras, si el cuerpo sufre un estrés, generará una respuesta que contrarresta ese estrés y vuelve a restaurar su estado anterior al mismo.

A. Esto implica una relación de causa y efecto (BP bajo --> retorno venoso bajo). No describe una respuesta fisiológica activa que contrarreste la caída de BP, como el aumento de la frecuencia cardíaca. No es homeostasis.

B. Nuevamente se describe una relación de causa y efecto. El engrosamiento de las paredes de los vasos sanguíneos no es una respuesta para contrarrestar el aumento de BP. No es homeostasis.

C. Aquí se describe una respuesta a un estrés. Los hombres están ingiriendo más agua. El cuerpo reacciona desechando ese exceso de agua, regresando el organismo a su estado anterior. Esto ilustra la homeostasis.

D. Esto suena como homeostasis, pero en realidad es lo opuesto a lo que sucede. La dilatación de los vasos sanguíneos periféricos es una forma en que el cuerpo pierde calor. Esto es lo contrario de lo que se debería hacer si el cuerpo se enfría; esto agravaría el estrés, lo que es contrariamente a la homeostasis. La respuesta natural a temperaturas frías es la constricción de los vasos sanguíneos para conservar el calor.

E. Esto describe homeostasis. El estrés es un aumento de glucosa. La respuesta del organismo para manejarlo es liberar insulina, que ayuda a reducir la glucosa de la circulación.

A volumetric flask is utilized for accurately measuring liquids in precise volumes. On the other hand, the filter flask, also referred to as a Büchner flask, resembles an Erlenmeyer flask but features thicker walls and a specialized side arm. Its primary purpose is for filtering liquids.

When the ribosome reaches a nonsense codon, which of the following occurs?
vlada-n [749]

Response:

The accurate answer is option - the polypeptide is released.

Explanation:

Non-sense codons are those that lack t-RNA and therefore do not specify any amino acids, resulting in the halting of the translation process.

The primary non-sense codons include UGA, UAA, and UAG, which signal the ribosome to cease translation, as these codons are not associated with any t-RNA, resulting in the ribosome letting go of the polypeptide through the E-site while concluding the process.

Consequently, the option - the polypeptide is released is accurate.
