Answers

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."

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.

Answers

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.

In the Gizmo, what light intensity and CO2 level do you think will maximize the rate of photosynthesis? (adjust the slider bars to determine this)

Answers

Answer:

Higher.

Explanation:

Higher light intensity as well as higher concentration of carbondioxide gas will increases the rate of photosynthesis because high light intensity allows the entering of carbondioxide gas inside the leaves through opening of stomata whereas carbondioxide gas is the reactant in the process of photosynthesis. If there are more reactants available so more food is produced in the form of glucose during the process of photosynthesis so we can conclude that high light intensity and carbondioxide levels increases the rate of photosynthesis.

Why humans need organs, like the liver and pancreas, but amoebas do not.

Answers

Answer:

They have no use for it, just like they dont have any type of respiratory organs like lungs.

Explanation:

In the case of nutrition and digestion they obtain food by capturing their prey with their pseudopodia. The food is internalized through a type of endocytosis known as phagocytosis. Nutrients are obtained as the enzymes digest the food inside the vacuole and when they are finished the food vacuole dissolves.

Humans need organs, like the liver and pancreas, but amoebas do not because human is a complex multicellular organism that necessarily requires a variety of organs in order to perform specific functions.

What do you mean by Organs?

Organs may be characterized as collections of tissues as a part of the body that performs a specific function. Some examples of organs may include the heart, the lungs, the kidneys, the stomach, etc.

Amoeba being unicellular organism has the capability to change their shape. They capture their food through pseudopodia and diffuse the substance easily through their single cells.

While on contrary, humans are more complex living organisms on this earth planet. So, they require a specific set of organs and organ systems in order to facilitate their survival.

Construct an argument based on data about the risks and benefits of renewable and nonrenewable energy resources.
Argument should consist of at least 100 words.

Answers

There are two major categories of energy: renewable and non-renewable.

Non-renewable energy resources are available in limited supplies, usually because they take a long time to replenish. The advantage of these non-renewable resources is that power plants that use them are able to produce more power on demand. The non-renewable energy resources are:

Coal
Nuclear
Oil
Natural gas
Renewable resources, on the other hand, replenish themselves. The five major renewable energy resources are:

Solar
Wind
Water, also called hydro
Biomass, or organic material from plants and animals
Geothermal, which is naturally occurring heat from the earth
While renewable energy resources have the advantage of unlimited supply over the long haul, they are limited in their availability at any given moment.

For example, the sun rises each day, but its ability to generate power is limited when its cloudy. Another disadvantage is that power plant operators can’t crank up renewable energy production when people are consuming more power, such as on a hot day when many people are running air conditioners at the same time.

States like California are trying to solve this problem by using energy storage, like large batteries, to collect electricity from renewable sources when demand is low in order to use it later when demand goes up. Non-renewable Energy and Climate Change

When coal, natural gas and oil are burned to produce energy, they emit heat-trapping gases such as carbon dioxide. This process of trapping heat is what drives climate change, and the failure to address this problem is what's catalyzing the current climate crisis.

Fossil fuels are hydrocarbon-containing materials like coal or gas that are found in the Earth’s crust and formed in the geological past from the remains of living organisms. These energy sources account for the majority of the world’s greenhouse gas emissions.

If emissions continue unrestrained, the atmosphere could warm by as much as 2.7 degrees Fahrenheit above preindustrial levels by the year 2040, according to the latest report from the Intergovernmental Panel on Climate Change, a group of international scientists empowered by the United Nations to advise world leaders.

Scientists say this increase in the temperature would threaten life on the planet in a myriad of ways, including severe water shortages; more air pollution; rising sea levels, habitat loss; heat waves; melting ice sheets in West Antarctica and Greenland; and destruction of the world’s coral reefs.

Over the last 150 years, humans are responsible for the vast majority of the increase of these gases in the atmosphere, and the burning of fossil fuels through activities like driving a car is the largest source of these emissions.

There is a vocal group of environmentalists and researchers —Stanford’s Mark Jacobson, who developed a state-by-state 100% renewable plan for one — who argue that the power grid should be supported only by renewable resources.

Policy makers who invest in renewable energy often do so with the goal of generating power without emitting these planet-warming gases. Hope this helps!

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.

Answers

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.
