4)plateaus
Answer:
The correct answer is 4. Plateaus.
Explanation:
A plateau is a relatively flat, relatively high-lying part of the earth's surface that is wholly or almost wholly bounded by steeply sloping terrains. There is a pronounced slope on at least one side. The original flat area has mostly risen vertically as a whole due to geological factors. It may possibly have been cut by rivers, giving the impression of a hill or mountain landscape, but this is not it.

Which of the following is the best representation of the limiting factors affecting the elk population in this ecosystem?
O Number of scavengers, number of wolves, number of scientists studying Yellowstone.
Number of scavengers, and harshness of winter
Number of wolves, and harshness of winter.
The elk have no limiting factors
Answer:
Number of wolves, and harshness of winter.
Explanation: I took the test
The combination of factors that is capable of limiting the population of elk in an ecosystem would be the number of wolves and the harshness of winter.
The limiting factors of a population are those factors that hinder the population of an organism from increasing unlimitedly. In other words, limiting factors hinder populations from reaching their biotic potentials.
Limiting factors can be density-dependent if they have correlations with the density of species or density-independent if they have no correlation with an organism's density.
Wolves generally prey on elks, so they limit the growth of elk's population in an ecosystem. A harsh winter will also limit the overall growth of the population of elk in an ecosystem.
Scavengers cannot be a limiting factor to elk's population because they only feed on carcasses.

at what point did the climate began to fluctuate more severely ? (2 points )
Answer:
Due to greenhouse gases.
Explanation:
When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..

¿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).

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.

Resuelve el problema relacionado con las etapas del ciclo menstrual: "Si el día fértil de la polola de Luciano es el 09 de noviembre y ella tiene un ciclo de 28 días ¿ Cómo puede calcular el primer día de menstruación de su polola en ese mes y el período fértil? En la respuesta debes registrar: Primer día de menstruación, Día de ovulación y período fértil.
Answer: El primer día de la menstruación comenzaría el 26 de octubre y el período fértil es desde el 6 de noviembre hasta el día 9 (fecha de ovulación)
Explanation:
El ciclo menstrual está compuesto por cuatro fases: menstruación, fase folicular, ovulación y fase lútea.
Menstruación: Eliminación del revestimiento engrosado del útero (endometrio) del cuerpo a través de la vagina. El flujo menstrual contiene sangre, células del revestimiento del útero (células endometriales) y moco. La duración media de un periodo es de entre tres días y una semana.Fase folicular: Comienza con la menstruación y termina con la ovulación. La glándula pituitaria libera la hormona estimulante del folículo (FSH), estimulada por parte del hipotálamo. Esta hormona estimula al ovario para que produzca entre cinco y 20 folículos (nódulos o quistes diminutos), que se acumulan en la superficie. Durante la fase folicular, el folículo en desarrollo provoca un aumento del nivel de estrógenos. El hipotálamo, en el cerebro, reconoce este aumento y libera una sustancia química llamada hormona liberadora de gonadotrofina (GnRH). Esta hormona hace que la hipófisis produzca niveles elevados de hormona luteinizante (LH) y FSH. En el plazo de dos días, los altos niveles de LH desencadenan la ovulación. Ovulación: El óvulo es conducido hacia la trompa de Falopio y hacia el útero por medio de ondas de pequeñas proyecciones similares a pelos. La vida del óvulo típico es de sólo unas 24 horas. A menos que se encuentre con un espermatozoide durante este tiempo, morirá. Entonces, la ovulación consiste en la liberación de un óvulo maduro desde la superficie del ovario. Suele producirse en la mitad del ciclo, unas dos semanas antes de que comience la menstruación.Fase lútea: Durante la ovulación, el óvulo se desprende de su folículo, pero el folículo roto permanece en la superficie del ovario. Durante las dos semanas siguientes, aproximadamente, el folículo se transforma en una estructura conocida como cuerpo lúteo. Esta estructura secreta progesterona y estrógeno. Esta combinación de hormonas mantiene el revestimiento del útero engrosado, a la espera de que se adhiera un óvulo fecundado (implante). Si el óvulo fecundado se implanta en el revestimiento del útero, éste produce las hormonas necesarias para mantener el cuerpo lúteo. Esto incluye la gonadotrofina coriónica humana (HCG), la hormona que se detecta en un análisis de orina para detectar un embarazo. El cuerpo lúteo sigue produciendo los niveles elevados de progesterona necesarios para mantener el grosor del revestimiento del útero. Si no se produce el embarazo, el cuerpo lúteo se marchita y muere, normalmente alrededor del día 22 de un ciclo de 28 días. El descenso de los niveles de progesterona hace que el revestimiento del útero se desprenda (menstruación)La duración media del ciclo menstrual es de 28-29 días, pero puede variar entre las mujeres y de un ciclo a otro. La duración del ciclo menstrual se calcula desde el primer día de la menstruación hasta el día anterior al inicio de la siguiente.
Si consideramos que el primer día fértil es el 9 de noviembre y el ciclo es de 28 días, el primer día de la menstruación comenzaría el 26 de octubre y el período fértil es desde el 6 de noviembre hasta el día 9 (fecha de ovulación) Esto es porque la menstruación ocurre aproximadamente 14 días luego de la ovulación si el ciclo es de 28 días. Los días más fértiles son aproximadamente desde 3 días antes de la ovulación. Aunque en algunos casos, la fertilidad puede durar hasta dos días después de la ovulación.

A symbiotic relationship in which one species benefits and the other is harmed is known as mutualism. predation. commensalism. parasitism.
Answer:
Parasitism
Explanation:
Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.
A symbiotic relationship in which one species benefits and the other is harmed is called parasitism. The parasite lives on the food of the host. Fourth option is correct.
What are different types of symbiotic associations?In symbiosis, two organisms are present in close contact. There are different types of relationships seen in nature, such as mutualism, commensalism, parasitism, etc.
Mutualism occurs when two organisms, such as lichen, benefit from one another. Lichen is an association of algae and fungi. Algae makes food that is consumed by fungi, and fungi provide algae for a place to live.
In parasitism, one is the host, and the other is the parasite. An example is the tapeworm in the human intestine. Tape worms consume digested human food and harm humans by spreading their population. Here, the host is negatively impacted by the presence of parasites.
In predation, both are harmed as both are involved in the fighting. In commensalism, one party gets benefits while the other is not harmed by the association.
Hence, the fourth option is the correct answer, which is parasitism.

Easy points: Is this a good paragraph for my biology class??The question was why is it important for soil to contain nitrogen, phosphorus, magnesium, and potassium.
Soil is one of the main sources of nutrients needed by plants in order to grow. Nitrogen is used by plants for leaf growth and green color. Without nitrogen in the soil, the plant wouldn’t grow tall and produce enough food.Phosphorus is used by plants to help form new roots, make seeds, fruit and flowers.This is crucial because crops take up phosphorus only from the soil solution.Potassium helps plants form strong stems and fast growth. It also increases disease resistance.It triggers activation of enzymes and is essential for production of ATP. Magnesium is the central core of the chlorophyll molecule in the plant’s tissue. If Mg is deficient, the shortage of chlorophyll results in poor and stunted growth.
Answer:
It makes the roots absorb the nutrients easier
Explanation:
the roots of the plant are meant to absorb water and nutrients for the plants to manufacture food easly and to grow, the soil contain nutrients for the plants to absorb them.
