Para ya por favor Cual de los siguientes planteamientos se cumplen en relación a la energía en un ecosistema * A.La energía fluye de los heterótrofos a los autótrofos B.La energía, a menudo se libera de un ecosistema en forma de luz C.La organización de productores-consumidores y descomponedores muestra como la energía se concentra de manera mas alta en los descomponedores D.Para la mayoría de los ecosistemas la energía proviene de la luz
Answer:
D.Para la mayoría de los ecosistemas la energía proviene de la luz
Explanation:
Los ecosistemas requieren de un suministro constante de energía para poder sustentar la vida. A excepción de ecosistemas basados en fuentes hidrotermales, en general este aporte energético proviene del sol que suministra energía lumínica la cual es convertida por los organismos productores (por ej., plantas y algas) en compuestos orgánicos. Los productores representan la fuente de energía y alimento de consumidores primarios (por ejemplo, herbívoros), los cuales a su vez sirven de sustento para consumidores secundarios (por ej., carnívoros), estos suministran de alimento a los consumidores terciarios y así sucesivamente. Finalmente, los descomponedores son aquellos microorganismos que se alimentan de los restos orgánicos obtenidos a partir de productores y consumidores.

In 100 words or more, explain the role natural selection plays in causing biological resistance.
Plz help
Answer:
The ability of a microorganism to tolerate the effects of an antibiotic is known as antibiotic resistance. It's a certain kind of drug resistance. Antibiotic resistance develops naturally through random mutation, but it can also be engineered by putting a population under evolutionary stress. Bacteria will then transmit genetic information in a hominid-like manner once such a gene has been formed. Following the development of such a gene, bacteria may use plasmid exchange to transfer genetic information horizontally (between individuals). Multiresistant bacteria, also known as superbugs, carry several resistance genes. the reasons for it Transformation protocols can also be used to incorporate antibiotic resistance into a microorganism. This may be a good way to get artificial genes into a microorganism. Antibiotic tolerance is a product of natural selection in evolution. Antibiotic activity is a type of environmental pressure; bacteria that have developed a mutation that allows them to survive will continue to replicate. They will then pass this trait on to their children, resulting in a generation that is completely immune.

Clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish are just a few examples of the large variety of organisms that can be found in a coral reef. The coral reef and its inhabitants are suffering due to several factors such as pollution, coastal development, sedimentation and destructive fishing practices. What would be the most likely result if some of the species in the coral reef are destroyed? Other organisms would move into the coral reef area The coral reef would be allowed to flourish without so many fish and plants living in and around it. The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance. The waters surrounding the coral reef will become cool with the decreasing number of organisms living there

- What is the geocentric model of the
universe?
a) The Theory of Evolution
b) Newton's Laws of Motion
c) The belief that Earth is at the center of our solar system
d) Superstition
Answer:
I believe C,
Explanation:
The geocentric model of the universe maintained that the Earth was at the center of everything in the solar system. In it, the Sun and planets orbited around our planet. Many odd and elaborate adaptations were required to make this model agree with observations. This problem increased, as our our observations got more accurate.
The geocentric model was superseded by the heliocentric model, in which the planets all orbited the Sun. The Heliocentric model was eventually able to show that the positions of the planets over time were much more convincingly, and simply portrayed by it, than by the former model.
Apologizes if I'm wrong/
Answer: It is c because the person who made it or thought of it said that the earth is at center of the cosmos or the universe.

Which of the following is a true statement?
A. Disruptions in an ecosystem are normal and natural changes.
B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.

Answer:
is this a story or the question?
Explanation:
How would the finch populations on these islands change over time?
The finch population's beaks will be modified; on dry islands, they will have larger beaks, while on rainy islands, they will prefer medium or short beaks.
What is natural selection?Natural selection is an evolutionary mechanism. Organisms that are better adapted to their surroundings are more likely to survive and pass on the genes that helped them thrive. Species change and diverge as a result of this process.
Because of the differences in environmental conditions, the finch populations on the dry and wet islands are likely to change differently over time.
Finches with traits that allow them to efficiently extract nutrients from dry seeds would have an advantage on the dry island, where food and water resources are limited.
Natural selection would favour these traits over time, increasing the frequency of these advantageous traits within the dry island finch population.
Thus, this way, the finch populations on these islands change over time.

Answer:
The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron
Selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.
What is selective reabsorption?The selective reabsorption mechanism allows the absorption of different substances including glucose and amino acids in the urine.
This reabsorption occurs after filtration in the capillaries of the urinary system. The filtration and excretion of waste substances are associated with the formation of urea.In conclusion, selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.

Que tedria de particular la retina de un animal que no pudiera diferenciar los colores cuya vision fuera exclusivamente en blanco y negro
Answer:
La falta de células cono en la retina
Explanation:
En vertebrados, la retina se encuentra formada por dos tipos básicos de células denominados células conos y células bastones. Las células cono son unas células fotosensibles las cuales forman una capa concentrada en el centro de la retina. Estas células (células cono) son responsables de la distinción entre diferentes colores del espectro de luz visible. Las células cono se clasifican en tres tipos de acuerdo a su sensibilidad para distinguir la luz azul, roja, y verde. Esta sensibilidad se debe a la presencia de diferentes tipos de proteínas opsinas, las cuales confieren la capacidad de absorber la luz en una longitud de onda particular: cianopsina (sensible a la luz azul), eritropsina (sensible a la luz roja) y cloropsina (sensible a la luz verde). Animales como los gatos y los perros son daltónicos, es decir, no pueden completamente diferenciar los colores, debido a la falta de una o más clases de células cono (y por lo tanto también de opsinas) en la retina.

5' ends of the pre-mRNA strand in Model 1. Where would i put it??
Answer:
I think the right side is 3 prime and left sde is 5 prime
Explanation:
Because the process of transcription takes place in nucleus so it should be put inside the nucleus.
What is nucleus?In genomics, a nucleus is a membrane-enclosed organelle within a cell that houses the chromosomes.
What is Transcription?The process in which information of a strand of DNA is copied into a new m RNA molecule is known as Transcription.
The enzyme responsible for transcription is RNA polymerase. Transcription start when RNA polymerase binds to a promoter region at the start of a gene directly or through helper proteins. Initiation, Elongation, and termination are the three steps of transcription. Transcription is carried out with the help of enzyme RNA polymerase and some proteins known as transcription factors. Enhancer and promoter sequences are the DNA sequences on which transcription factors attach to initiate the transcription process by directing RNA polymerase to the correct transcription site.The transcription initiation complex is made up of transcription factors and RNA polymerase working together.
