Explique en que consiste el funcionamiento del SNC y SNP en el acto reflejo mencionando a lo menos 2 características del proceso
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 motorasModo de acción:
Rama ascendenteEl 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 descendenteUna 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.

2- DNA replication, each strand of DNA serves as a _______ for a newly synthesized strand of DNA.
3- In gene expression, DNA is used as a template to make _______, which is then used as a template to make a polypeptide.
4- In the process of _______, DNA can be rearranged, which contributes to the genetic diversity of the species.
5- What are the differences between the structures of DNA and RNA?
6- How can the central dogma help us understand the process by which DNA is turned into protein? What are the two steps involved in the process of gene expression?
7- Why are replication and recombination two important roles of DNA?
Answer:
1.hydrogen
2.template
3.mRNA
4.recombination
5.DNA and RNA are both made up of nucleotides. RNA is comprised of adenine, uracil, guanine, and cytosine. DNA is made up of adenine, thymine, guanine, and cytosine. DNA is a double-stranded chain of nucleotides comprised of base pairs that form a double helix. RNA is often a single-stranded chain of nucleotides.
6.The central dogma states that DNA contains the genetic code needed to make proteins—a process known as gene expression. Transcription and translation are the two steps involved in gene expression. In transcription, the DNA code is turned into RNA. In translation, the RNA sequence provides instructions to the cellular machinery to manufacture polypeptides, which become proteins.
7.Replication is the duplication of DNA, and it is important because, in cell division, each daughter cell must contain an exact copy of the original cell's DNA, since DNA contains the instructions required to make all of the cell's tissues. Recombination is the natural process for genetic sequences in a chromosome or between chromosomes to exchange genetic information. Recombination is important in nature because it produces genetic variations that may be preserved because of natural selection. Recombination also can be used in the laboratory to combine the genetic code of two different organisms.

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=whiteWhat 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:

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?
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.

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.

Explanation:
The Paleozoic era lasted for approximately 291 million years. The The Paleozoic Era is a significant period in the geological history of the planet.
The Paleozoic Era, commonly referred to as the Age of Ancient Life, is a key period in the geological history of the Earth, lasting roughly between 541 and 252 million years ago. The Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian are its six distinct time eras. The Paleozoic Era saw incredible evolution and the creation of numerous life forms, which laid the groundwork for the diversity of life that can be seen on Earth today. Life underwent a remarkable period of diversity during the Cambrian Period known as the "Cambrian explosion." Trilobites, brachiopods, and early arthropods were among the complex, hard-shelled animals that first emerged as a result of this surge.

Answer:
Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

Name one trophic level that contains autotrophs and one trophic level that contains heterotrophs.
Answer:
producers and secondary consumers
Explanation:
autotrophic means they make their own food. such as plants and heterotrophs is anything that eats other things to obtain energy. so this could be the second or third trophic level just depends on all the information you are given and what you want to choose.
The name of one trophic level that contains autotrophs is Producers, while the name of one trophic level that contains heterotrophs is the primary consumer.
What do you mean by Trophic level?A Trophic level may be defined as a sequential position of organisms in a food chain of an ecosystem.
Autotrophs are those groups of organisms that synthesize their own food in the presence of sunlight. They are the foundation of the trophic level.
Heterotrophs are those groups of organisms that depend on autotrophs in order to take energy for metabolism and other work.
Therefore, the name of one trophic level that contains autotrophs is Producers, while the name of one trophic level that contains heterotrophs is the primary consumer.
