D. It reacts to form carbon dioxide and water.

Answers

Answer 1
B
Expiation

Sorry if it’s wrong
Answer 2

Aerobic respiration involves the reaction of oxidation which involves the acceptance of electrons when the molecular oxygen reacts with protons to form water molecules. Thus, the correct option is A.

What is Aerobic respiration?

Aerobic respiration is the chemical process in which molecular oxygen is used to make the energy in the form of ATP from carbohydrates. It is also called as aerobic metabolism, and oxidative metabolism.

Aerobic organisms can use molecular oxygen (O₂) to generate energy in the form of adenine triphosphate (ATP). The role of molecular oxygen in the process of cellular respiration is to act as the end acceptor of electron. As the electrons are dropped off at the inner mitochondrial membrane during the process of cellular respiration, they travel through the electron transport chain and  are finally accepted by the molecular oxygen to form water.

Therefore, the correct option is A.

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.

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.

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.

There would be no familiar faces to greet him when he arrived. But Altaf could expect the children to hear his call.The dub-dub rhythms of the engine spread out and beckoned every boy and girl within earshot. Their short brown legs kicking up a cloud of dust, they flocked to the riverbank. They jumped up and down, their shrill voices piercing the air.Altaf had encountered this scene a hundred times as he made his way east from Calcutta through the tangled waterways of the delta. This time his motorboat did not rush past the children. It slowed down and headed right towards them. Their jumps turned into stomps and their shouts became screams of delight. When he cut the engine, Altaf heard what they were saying.Ingreji-shaheb! Ingreji-shaheb!From the back of the boat, Shiraj chuckled, They think you are an Englishman. Altaf smiled. Why not? These children might never have seen the English but having just crowned George the Sixth as Emperor of India,1 they were still the masters of this land. Altaf doubted that any other motorboat had ever come into this village. No one would expect a Bengali man to bring one here. Besides, Altaf was taller than average, fair in complexion, and wearing European clothes. He would have been more comfortable travelling in a lungi2, but today he had put on khaki pants and a sky-blue shirt. A straw hat protected his head from the sun.Exhausted after three days of travel, Altaf was relieved the journey was over. When he had turned off the Meghna river and entered this smaller channel, he was not sure this was the one that led to his village. Then he sighted, on the horizon, the corrugated iron roof framed by the twin palmyra trees with their broad leaves spread like huge fans. Home.Still, he could not be positive. He was returning after ten years. This is Modhupur village, isnt it? he shouted at the children.He-speaks-in-Bangla. Not-an-Ingreji-shaheb! Our-folk! One-of-us!He repeated his question.Yes-this-is-Modhupur. But-who-are-you? Who-do-you-want? Where-did-you-come-from?I belong to that house over there, he said, thrusting a finger towards the palmyra trees.The children swivelled their necks to look. None of them were old enough to remember him. They questioned him and each other. Are-you-this-ones-brother? Is-he-that-ones son? The-other-ones-cousin? Finally a voice made itself heard over the rest and said, Masooms-uncle-who-went-away-to-the-city. It could have been the certainty in his voiceslightly older than the othersor they may have run out of possibilities to consider, but the boys remark settled the debate. The children quieted down and just stared at Altaf, as if searching his face for some sign of familiarity so they could place him as part of their world.Clutching the mooring rope in his hands, Shiraj jumped into the water and tugged the boat towards the bank. A few of the children rushed forward to help him pull. Shiraj tied the rope around a tree. Nearby a few small dinghies were also moored. They rocked in the water from the waves stirred up by the motorboat.While Altaf supervised the mooring, the children craned their necks to look inside the boat and resumed their inquiries. Where-are-your-sails? How-can-it-move-without-sails? What-is-that-thing-you-call-an-engine? Why-does-it-make-the-loud-noise? Where-did-you-get-it-from? Are-you-a-very-rich-man?Altaf could not keep up with them. With each reply, they pelted him with a dozen more questions. At times he felt like telling them to shut up, but he enjoyed their attention. Their chatter distracted him from what lay ahead.Leaning over the bow of the boat, he passed his bedding and leather suitcase to Shiraj.
