Answer:
B. Geosphere and biosphere.
Explanation:
Earth as a planet can be subdivided into subsystems called "spheres". The spheres that make up the Earth are as follows; geosphere or lithosphere, hydrosphere, atmosphere, biosphere etc.
As related to this question:
- The GEOSPHERE refers to the solid part of the Earth, which involves rocks, minerals etc. of the Earth crust. It can be regarded to be the physical land.
- The BIOSPHERE refers to a collection of all the living organisms inhabiting the Earth. This includes plants, animals, microbes etc.
According to these question, surface mining for coal is an act that involves removing all the vegetation and rock above the coal being mined. This means that the physical land/rocks (geosphere) and vegetation of plants (biosphere) covering the coal beneath are affected. Hence, based on the explanation above, GEOSPHERE and BIOSPHERE are two of Earth's subsystems most immediately affected by surface mining.

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.

Explanation:
Which model of replication did the actual results of the Meselson-Stahl experiment support? Explain your answer.
Answer:
Semi-conservative replication
Explanation:
After the double-helix discovery of Watson and Crick, there were three possible models about the DNI replication:
The Conservative model stated that the two strands of DNI together were the template of another new molecule. The final product was the original double-stranded molecule and the new molecule. The semi-conservative model stated that the original DNI molecule separated into two strands, and each of them served as a template for the synthesis of a new complementary strand. The replication product would be two double-stranded DNA molecules, each carrying an original strand a new one. The Dispersive moles stated that the replication product would be two molecules made by a mixture of segments of the original and the new molecules.Meselson and Stahl joined to discover which of the models was the correct one. To do it they used E. coli and Nitrogen isotopes.
First, they extracted DNI from bacteria grown in a medium with N¹⁴ and got its density band by centrifugation. Then they grew bacteria in a medium with N¹⁵, extracted their DNI molecules, centrifugated them, and got the density band, which was heavier than the firsts ones. The researchers then transferred bacteria grown in medium with N¹⁵ to a medium with N¹⁴, and they allowed only one replication process to occur. DNI was extracted and centrifugated again, and a new band appeared. This band was an intermediate form between bands of DNI-N¹⁵ and DNI-N¹⁴.This event eliminated the conservative model. If this model were correct, the expected result would be to get two bands: one corresponding to the density DNI-N¹⁵ and the other corresponding to the density DNI-N¹⁴.
Bacteria grown in a medium with N¹⁵ and then transferred to a medium with N¹⁴ were finally allowed to replicate twice. Their DNI was extracted and centrifugated. The result was two bands: one of them coincided with the intermediate band, and the other one with the DNI-N¹⁴.This result was conclusive because if the dispersal model were correct, these two bands should not appear, as all the DNI strands would have part of the original molecule.
With this experiment, Meselson and Stahl proved that the correct replication model was the semi-conservative one.

Does myostatin defiency make you grow muscle faster then normal?
Answer:
Deficiency in myostatin resulted in increased muscle mass (1, 6, 15–18), but that this increase was not accompanied by a proportionate increase in force generation.
Explanation:
These findings clearly indicate that the increase in muscle mass of myostatin mutant animals confers no strength advantage over wild-type controls.

Answer:
it is to do with something called angular moment. Gravity is the central force in the Universe, because it is the only one which has a significant pull over large distances.
5:Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. ... These forces of inertia and gravity have to be perfectly balanced for an orbit to happen.

Melinda and Bart are sitting beside each other in the third car of a roller coaster.
From whose reference point are Melinda and Bart moving away from the observer?
A. a person sitting in the first car of the roller coaster
B. a person standing on the ground behind the roller coaster
C. a person sitting in the last car of the roller coaster
D. a person standing on the ground in front of the roller coaster
Answer:
The answer option that you are searching for today is the option "B."
From the reference point of a person standing on the ground in front of the roller coaster, Melinda and Bart are moving away from the observer. Therefore, option (D) is correct.
What is the reference point?A reference point is a fixed location or object used to determine the position, speed, and direction of motion of an object or person in motion. It is used in physics and other sciences to describe the motion of objects.
This is because the roller coaster is moving forward along the track, and the third car, where Melinda and Bart are sitting, is behind the first and second cars. As the roller coaster moves forward, the distance between the third car and the person standing on the ground in front of the roller coaster increases, indicating that Melinda and Bart are moving away from that observer. Therefore, the correct option is D, "a person standing on the ground in front of the roller coaster."

Pollutants concentrated in the northern part of the Gulf of Mexico often create a dead zone. A dead zone is an area of an aquatic ecosystem that does not have enough oxygen to support sea life. Some of the chemicals that cause the Gulf dead zone come from as far away as Montana. Use this information and what you know of United States geography to select the statement that BEST explains how pollutants from Montana have an impact in the Gulf of Mexico.
Answer and Explanation:
Hello. You did not present the answer options, but we can say that Montana pollutants have an impact on the Gulf of Mexico, due to the Mississippi River. That's because Montana and the Mississippi River are in the same hydrographic basin, which causes Montana pollutants to reach the Mississippi River, which takes these pollutants to the Gulf of Mexico, as the Mississippi River flows into the Gulf of Mexico.
Therefore, we can say that Montana pollutants are easily taken to the Gulf of Mexico and this impacts marine life in an influential way.

¿Qué sucede si una célula se encuentra en la fase G0 del ciclo celular? ¿qué células nunca salen de esta fase?
Answer:
las células en fase G0 no se dividen. Un ejemplo de células en fase G0 son las neuronas y las células del músculo de corazón
Explanation:
El ciclo celular es una serie de eventos asociados al crecimiento y división de una célula. El ciclo celular consta de una fase de crecimiento o 'interfase' (la cual a su vez se divide en 3 fases: la fase G1, S y G2) y la fase de división celular (la cual a su vez se divide en mitosis y citocinesis). Sin embargo, hay células que no entran en fase G1 y en lugar de ello se dirigen a un estadio celular conocido como fase G0. La fase G0 es una es un estadio en el cual se encuentran células maduras que no se dividen hasta recibir un estímulo/señal que dispare la entrada de la célula en fase G1, donde la célula sintetiza los ARN mensajeros y proteínas necesarios para las etapas celulares posteriores que conducen a la división celular. Las células en fase G0 no crecen, pero poseen un metabolismo activo. Ejemplos de células en fase G0 incluyen las neuronas, células musculares poli-nucleadas, hepatocitos, etc. (es decir, células maduras y post-mitóticas que son incapaces de reproducirse).

Answer:
This discovery is known as heredity.
Explanation:
In the question above, we can see an example of heredity, which is the process where a trait is passed from an ascendant to a descendant. As seen above, the wrinkled seed is a characteristic that was passed on to a plant through its parent, the plant that gave rise to it. The characteristics passed by heredity are transmitted through the continuous transfer of genetic material, present in the DNA. Since the descendants have the DNA of their parents, it is possible that the characteristics are transmitted as the generations advance.

The teacher asked the students to explain why the population of deer had a large increase in population size. Which student's argument MOST accurately explains the increase in the deer population? A Student 4: The deer population increased because with fewer mountain lions, coyotes, and babcats there was less competition within the deer population. B. Student 1The number of deer increased because deer populations are always increasing, even when there are mountain lions, coyotes, and bobcats preying on them. Student 3: The number of deer increased because with fewer mountain lions, coyotes, and bobcats, the deer had more food available to eat. D Student 2: The number of deer increased because without mountain , coyotes, and bobcats, the deer longer and had more offspring that also lived longer,
Answer:
A. student 4
Explanation:
The population of deer increase because with fewer mountain lions, coyotes and bobcats there was less competition within the deer population
The correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."
What is food chain?The food chain describes the feeding relationships that exists in nature. Now this ecosystem has the food chain; grass ---> Deer ----> babcats ---> coyotes ----> mountain lions.
Now we are also told that the mountain lions eat the the bobcats and the hunters are killing the mountain lions, coyotes, and bobcats, the predators of the deer hence been removed hence the deer population multiplies.
Therefore, the correct statement is that; The number of deer increased because without mountain , coyotes, and bobcats, the deer lived longer and had more offspring that also lived longer."
