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.

As an embryo developed, identical cells give rise to specialized cells that platform different functions.
Answer:
As an embryo develops, identical cells give rise to specialized cells that perform different functions.
Explanation:
As an embryo develops, the cells divide, giving new ones. As the cells grow and continue to reproduce themselves, they differentiate, becoming specialized cells. These cells will be located in a particular part of the embryo and will perform a specific function. The shape, size, and organelles vary according to their role.

On a warm day near the ocean, a breeze or wind often blows from the water to the land. Explain why this happens
Answer:
It occurs because of the difference in temperature between the ocean and the land.
This happens because the land heats up faster than the water, causing the air to rise above the land and allowing cooler air from the ocean to move in and take its place.
What is sea breeze?Because land and water have different capacities for holding heat, the land will heat up more quickly than the water on a hot day near the ocean. As a direct consequence of this, the air that floats above land tends to become warmer and less dense than the air that floats above water. Because of this, a region of low pressure is created over the land, while a region of high pressure is created over the water. In order to maintain a natural equilibrium, air will always move from areas of higher pressure to areas of lower pressure.
A breeze or wind that blows from the water to the land is caused by the air that is cooler and denser over the water moving towards the air that is warmer and less dense over the land. This phenomenon, which is referred to as a sea breeze, can assist in moderating temperatures on land, thereby making it feel more bearable and pleasant to be there.

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.

If anyone answer these questions
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.
6;Gravity is the force that keeps planets in orbit around the Sun.
7.gravity
The dynamics of a rotating body is of course controlled by forces like gravity. Kepler's laws are a direct consequence of gravity
8.Rather, the term is derived from the concept of the tide "springing forth." Spring tides occur twice each lunar month all year long, without regard to the season. Seven days after a spring tide, the sun and moon are at right angles to each other

Landscapes with a faulted and folded surface bedrock structure, steep slopes, and high elevations are classified as
1)mountains
2)lowlands
3)plains
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.

¿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.
