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.

When a population of organism eats another, how can each population as well as the ecosystem change?
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.

The enzyme pepsin is produced in the cells of the stomach but not in the cells of the small intestine. The small intestine produces a different enzyme, trypsin. The reason that the stomach and small intestine produce different enzymes is that the gene that codes for pepsin is A) in the cells of the stomach, but not in the cells of the small intestine B) mutated in the small intestine C) digested by the trypsin in the small intestine D) expressed in the stomach but not expressed in the small intestine
Answer:
D) Expressed in the stomach, but not in the cells of the small intestine
Explanation:
The stomach and small intestine produce different enzymes is gene codes for pepsin is expressed in the stomach but not expressed in small intestine.
What is the function of trypsin?Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, the process of digestion that formed in the stomach.
Is a proteolytic enzyme produced by the pancreas in an inactive form called trypsinogen.
Thus, option "D" is correct as trypsin is expressed in stomach for protein breakdown.

They can create deep valleys is true about folds.
What are Deep valleys?
The combined effects of gravity, water, and ice result in valleys, which are low-lying sections of land that have been eroded and washed out. Some are hollow, while others hang.
The majority of primary valley cuts are made by rivers and streams, creating sides with high walls and a narrow floor that from a distance resembles the letter "V." The steepness of the sides and the width of the floor are both influenced by the gradient of the river, or how quickly it descends.
Waters add to the land's natural twists as they move toward the sea by removing sediment from bends' exteriors.
Therefore, They can create deep valleys is true about folds.

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:
A poor insulator!
Explanation:
Since Iron has molocules so close together it CAN conduct heat very well. Because of this A and C are not relavent options.
Thermodynamics is "the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy."
Due to the fact iron is a strong conductor, it IS bound to the law od thermodynamics. It's a very easy conceept to understand, you just have to pay attention a little bit and searching up definitions can help too!
