Answer: The hormones secretin and cholecystokinin act on the pancreas, stomach, and gallbladder.

Explanation:

The duodenum produces two more hormones. Cholecystokinin (CCK), similar to enterogastrone, is released when fat is present in the chyme. CCK promotes the contraction of the gallbladder, which releases bile into the duodenum to help emulsify and digest fat more effectively. The other hormone from the duodenum is secretin. In response to the acidic chyme entering the duodenum, secretin triggers the pancreas to release bicarbonate, thereby neutralizing some of the acid.

A gene is a segment of DNA that typically contains the code for a particular protein influencing a specific trait, while an allele is a segment (a version) of that gene. The correct choice among the options is option "D".

Answer:

Reena is composting as a method to recycle biodegradable waste, transforming it into a natural fertilizer.

Explanation:

By placing the organic material into the soil-filled pot, soil-dwelling microorganisms are able to break down the waste, producing fertile matter. This enriched soil is beneficial for plant health, providing essential nutrients needed for growth.

Composting involves a biological oxidation process that is regulated, with microorganisms and other decomposers like earthworms facilitating the breakdown of solid waste. The final product serves as a natural fertilizer and acts as an alternative to chemical options. It's crucial to manage temperature and humidity during this process, which may last between one to two weeks until all solid waste is decomposed and integrated with the soil.

Renal glucose reabsorption.

Respuesta:

El orden correcto es:

1. Gran cantidad de glucosa en la sangre, enviando señales hacia el páncreas.  
2. Síntesis de hormonas por células beta.
3. Unión de hormonas con receptores en el hígado.
4. Ingesta de moléculas de glucosa de la sangre por transportadores específicos.
5. Liberación de hormonas desde los receptores

Explicación:

• El páncreas produce dos hormonas clave para la regulación de los niveles de glucosa en la sangre.
• Las dos hormonas, glucagón e insulina, aumentan y disminuyen el azúcar en la sangre respectivamente.
• La insulina reduce la glucosa en sangre al estimular las células del cuerpo para que aumenten la ingesta de glucosa.
• El cerebro detecta la alta/baja glucosa en sangre y, a continuación, envía señales al páncreas para iniciar la síntesis de insulina o glucagón por las células beta.
• Estas hormonas se unen a receptores en las células del cuerpo; en las células hepáticas, en el caso de la insulina.
• Los receptores inician la señalización celular que facilita la entrada o salida de glucosa dentro o fuera de las células del cuerpo.
