Answer:

Jupiter

Explanation:

I would say that because Jupiter already has a lot of mass on it and I would suspect that you would too. But I am not sure if it is 100% right, so correct me if I am wrong! Have a nice day! :)

Answer:

The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that Are regulated steps.

Explanation:

Glycolisis and gluconeogenesis are two mechanisms related to the carbohydrates metabolism. Sometimes they are considered reverse processes. However, they are different because of the control points they have where reactions are irreversible.

Glycolisis and gluconeogenesis share 7 common reactions, that are reversible. Thses reactions are coordinated and regulated by F-2 and 6-BP as the answer to the hormonal action.

Glycolisis happens in the muscle, while Gluconeogenesis happens in the liver. Together they form the "Cori Cycle".

kolezko [41]

Complete question:

¿Cual de los siguientes solutos que pueden estar presentes en el liquido extracelular es transportado de acuerdo al modelo de mecanismo propuesto en la ilustracion?

A) Etanol.

B) Calcio.

C) Glucosa.

D) Estrógeno.

E) Oxígeno.

Nota: La ilustración se encuentra como un archivo adjunto.

Answer:

Ión Calcio y Estrógeno son transportados por proteinas canal a traves de la membrana.

Explanation:

Durante el paso de sustancias al interior o exterior de la celula ocurren dos tipos de transportes. Transporte activo y pasivo. El primero requiere de energia ya que se produce en contra de un gradiente electroquímico. El segundo, por otra parte, no requiere de energía ya que sucede a favor del gradiente electroquimico.

El transporte activo es mediado por proteinas transportadoras que actúan como bombas transportadoras.

El transporte pasivo puede ocurrir por

difusión simple a traves de la bicapa lipídica (sin ningunaproteina que medie su paso),
difusión facilitada a traves de proteinas canales (estas proteinas tienen forma de poro hidrofílico y permiten el paso de sustancias de un lado al otro de la membrana celular sin sufrir modificaciones. Permiten el pasaje de iones actuando como canales ionicos y de hormonas o neurotransmisores),
o difusión facilitada a través de proteinas transportadoras o carriers (estas proteinas son altamente selectivas y sufren un cambio temporal en su conformación al hacer pasar una sustancia de un lado al otro de la membrana plasmatica).

La ilustración adjuntada muestra un ejemplo de proteina de canal facilitando el transporte de distintas sustancias.

A) Etanol. Transporte pasivo. Difusión simple a traves de la bicapa lipídica.

B) Ion Calcio, Ca²⁺. Transporte pasivo. Difusión facilitada a traves de proteina canal.

C) Glucosa. Transporte pasivo. Difusión facilitada a traves de proteina transportadora o carrier.

D) Estrógeno. Transporte pasivo. Difusión facilitada a traves de proteina canal.

E) Oxígeno. Transporte pasivo. Difusión simple a traves de la bicapa lipídica.

deff fn [24]

Answer:

a. The allele for round seeds is dominant to the allele for wrinkled seeds.

Explanation:

Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.

A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".
