A student observes the model and claims that the total mass of the reaction is conserved. Is the student's claim correct? Why or why not? A No, because the arrangement of atoms is different in the reactants and products. B Yes, because the reactants and products are made of atoms of the same elements. C Yes, because the number of atoms of each element is the same on both sides of the equation. D No, because the total number of atoms in products is greater than the total number of atoms in reactants.

Answers

Answer 1

C.  Yes, because the number of atoms of each element is the same on both sides of the equation.

Due to the law of conservation of mass, any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

1- Evaporation:-

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. For more evaporation, the area that surrounds the surface of the water must be less humid i.e. it should not already be concentrated have the water vapors. For the evaporation we need to increase the temperature of the molecules of water on the surface, which is caused by the Sunlight.

Which statement best compares the amount of fossil fuels formed each year to the amount used each year? The amount of fossil fuels formed is exactly the same as the amount used. The amount of fossil fuels formed is approximately the same as the amount used. The amount of fossil fuels formed is much less than the amount used. The amount of fossil fuels formed is greater than the amount used.

Answers

Answer:

The amount of fossil fuels formed is much less than the amount used.

Explanation:

Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.

One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.

An on-going research study has been tracking the dietary preferences of gorillas in the wild. Researchers are hoping to formulate a diet for gorillas in captivity that mimics those living in their natural habits. By reproducing the preferred diet, researchers hypothesize that the eventual release back into the natural habitat will be an easier transition for the gorillas.

Researchers are using various methods to make observations and collect data about the feeding habits of gorillas in the wild. Which method would be classified as direct observation?
A) Counting and classifying the debris in the area where the gorillas live.
B) Observing the gorillas from a protected location and recording what they eat.
C) Surveying the natives in the area about the diet of the local gorilla population.
D) Photographing the habitat of the gorillas in a before and after scenario and seeing what is missing from the after photograph.

explain why soil micro-organisms should break down plant and animal residues​

Answers

Hello there wish you a GREAT Thanksgiving :)

Microbial Soil Orga​nic Matter Decomposition

Organic matter decomposition serves two functions for the microorganisms, providing energy for growth and suppling carbon for the formation of new cells. ... Dead plant residues and plant nutrients become food for the microbes in the soil.

Microbes thrive underneath no-till conditions and winter cover crops. cowl plants and manure may be used to feed soil microbes and recycle soil vitamins. As soil microbes decompose organic residues, they slowly release vitamins lower back into the soil for the winter cowl vegetation or for the preceding crop.

Why soil microorganisms should break down plant and animal residues?

By-products from growing roots and plant residues feed soil organisms. In turn, soil organisms support plant health as they decompose organic matter, cycle nutrients, enhance soil structure and control the populations of soil organisms, both beneficial and harmful (pests and pathogens) in terms of crop productivity.

What's the significance of microorganisms within the soil what's their role?

Useful soil microbes carry out fundamental capabilities which include nutrient cycling, breaking down crop residues, and stimulating plant boom. at the same time as the position of microbes to preserve soil fitness and make contributions to crop performance is clear, the soil organic factor is extremely difficult to take a look at and control.

What is one advantage of urbanization?

Answers

Answer:

Advantages of Urbanization

Urban residents in many parts of the world tend to live longer than do rural residents, and have lower infant mortality and fertility rates. Cities provide better access to medical care, family planning, education, and social services. Recycling is more economically feasible.

Ventajas de la urbanización:

Crecimiento sostenido. El crecimiento de las ciudades va acompañado de una mayor demanda de servicios básicos y de bienes de consumo, lo cual genera un mercado mayor a satisfacer.

Concentración poblacional. Las ciudades son ámbitos más controlables por los Estados y con mayor facilidad de cobertura de redes de servicio o de distribución, dado que la población se concentra en algunos kilómetros a la redonda.

Complejización laboral. El mercado de empleo en la ciudad es mucho más diverso y variado que en las zonas rurales, permitiendo así el desarrollo y complejización de las actividades industriales, comerciales y de servicios.
