Explique en que consiste el funcionamiento del SNC y SNP en el acto reflejo mencionando a lo menos 2 características del proceso

Answers

Answer:

SNP → Envía la información de los estimulos al SNC (neuronas aferentes) y lleva una respuesta hacia los efectores (neuronas eferentes).

SNC → Recibe la informacion que envia el SNP, la procesa y envía una respuesta hacia el organo efector (interneuronas).

Explanation:

Al hablar del arco reflejo se hace referencia a la secuencia de pasos que se llevan a cabo para que el cuerpo reaccione ante un estímulo externo.  

En términos gerenales, el sistema nervioso periférico recibe informacion a modo de estimulo del medio externo. Esta información es enviada al sistema nervioso central, donde se procesa y se envía una respuesta adecuada en función del estimulo. Este mecanismo es el arco reflejo.

Existen tres tipos de neuronas involucradas en el arco reflejo.  

Neuronas aferentes o sensoriales Interneuronas Neuronas eferentes o motoras

Modo de acción:  

Rama ascendente

El estímulo llega al cuerpo y es recibido por receptores sensoriales especializados que responden a ellos. La información recibida por estos receptores, es convertida de energia del estímulo (temperatura, luz, presión, etc) a energia del potencial de acción.  

Las neuronas aferentes, ubicadas en la dermis y epidermis, reciben la información de los receptores, reaccionan al estímulo y envian esa información al sistema nervioso central a modo de impulsos nerviosos.

Rama descendente

Una vez que la información llega al sistema nervioso central, es procesada por las interneuronas, quienes cumplen la función de análisis y procesamiento de toda la información para enviar una respuesta. Las interneuronas manejan muchas de las señales sensoriales, las evaluan, las comparan, y envian una respuesta motora.

Las neuronas eferentes reciben esta respuesta de las interneuronas, y son estimuladas para llevar estas nuevas señales desde el sistema nervioso central hacia las células de los organos efectores. El órgano efector en general puede ser un músculo o una glándula.

Finalmente, el tejido de destino responde al estimulo a modo de contracción, en caso de tratarse de un músculo, o de liberación hormonal, en caso de tratarse de una glándula.

Answers

Answer:

Después de la fecundación, la célula recién formada llamada cigoto lleva a cabo divisiones sucesivas hasta desarrollar un nuevo individuo. Estas divisiones se llevan a cabo mediante el proceso llamado segmentación.

Explanation:

Luego de que se produce la fecundación del óvulo y se forma el cigoto, los 3 a 4 días que le siguen abarca un proceso llamado segmentación. En este proceso se producen sucesivas divisiones celulares dando blastómeros, los cuales son células que forman el embrión y a las estructuras que este necesita para desarrollarse. La segmentación es un proceso que ocurre en las trompas de falopio mientras el cigoto se desplaza hacia el útero donde se implantará.

Actually Welcome to the concept of Genetics and color.

According to the above condition, we will get the remaining results of crisscross as,

4.) YYPp ==> Yellow

5.) YyPp ==> Orange (both expressed)

6.) yyPp ==> Pink

7.) YYpp ==> Yellow

8.) Yypp ==> Yellow

9.) yypp ==> White

In this case, we have to recognize the concepts of genetics, so the phenotype for each exercise color:

YYPP=orangeYyPP=orangeyyPP=pinkYYPp=orangeYyPp=orangeyyPp=pinkYYpp=yellowYypp=yellowyypp=white

What is a phenotype?

Phenotype is an important concept adopted in Genetics and is usually defined as the set of observable characteristics of an organism. In this sense, the morphological and physiological characteristics of an individual are included in this set.

So from the information given in the statement we have that:

When both pigments are expressed, the flowers appear orange.When only one pigment is expressed, the flowers are either yellow or pink.When neither pigment is expressed, the flowers appear white.

Phenotypes are expressed by the following colors:

YYPP=orangeYyPP=orangeyyPP=pinkYYPp=orangeYyPp=orangeyyPp=pinkYYpp=yellowYypp=yellowyypp=white

Significado del acoplamiento entre CTE y FosOx, es de bioquimica si alguien me puede ayudar por favor

Answers

Answer:

La teoría quimiosmótica indica que la cadena de transporte de electrones (CTE) y el proceso de fosforilación oxidativa (FosOx) están acoplados por un gradiente de protones.

Explanation:

La teoría del acoplamiento quimiosmótico propuesta por Peter Dennis Mitchell permite entender cómo el ADP se fosforila a ATP en mitocondrias y cloroplastos. La energía que se libera durante la cadena del transporte de electrones es utilizada por la célula para crear un gradiente de protones a través de las membranas internas de mitocondrias y cloroplastos. Subsecuentemente, la energía potencial creada a partir de este proceso es liberada por el movimiento de protones a favor de un gradiente electroquímico. Finalmente, la energía potencial creada a partir del flujo de electrones es acoplada a la fosforilación oxidativa para sintetizar enlaces fosfato de alta energía en el ATP a partir de ADP y fosfato (Pi).

8. The graph below shows the reaction rates of two different reactions. Which of the following statements could explain the difference in the two reactions? ​

Answers

Answer:

These two reactions have different reactants, bonding and catalysts.

Explanation:

The two reactions are different from one another due to fusion of different reactants as well as different products. These two reactions may have different types bonding i.e. covalent, ionic or metallic bond etc between their atoms. In these two reactions, different types of catalyst are used which helps in speedup the chemical reaction so we can conclude that these two reactions have different reactants, bonding and catalysts in their chemical reaction.
