Explanation:

Fossils are preserved remains of organisms. They are preserved in two ways. They can be the actual remains of organisms.

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.  

Modo de acción:  

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.

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.

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:

D. they can create deep valleys

Explanation:

Hope this helps ⭐

They can create deep valleys is true about folds.

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.

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.

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.

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.

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.

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.
