Answer:

We can use less pollutants.

Explanation:

Gracias a una investigación internacional se ha averiguado que las actividades humanas causan estragos en los bosques tropicales al alterar el ciclo de nitrógeno normal. Los descubrimientos, publicados en Science, proporcionaron las primeras pruebas de efectos a largo plazo por contaminación de nitrógeno en árboles tropicales. Los científicos, de Austria, Canadá, Alemania y Panamá, trabajaron en dos emplazamientos remotos del Observatorio Terrestre Global del Instituto Smithsonian en Panamá y Tailandia. «La contaminación atmosférica fertiliza los bosques con uno de los nutrientes más importantes para el crecimiento», afirmó S. Joseph Wright del Instituto Smithsonian de Investigación Tropical en Panamá. «Comparamos el nitrógeno que contenían hojas de especímenes secos recogidas en 1968 con el de muestras de hojas de 2007. La concentración de nitrógeno foliar y la proporción de isótopos de nitrógeno tanto pesados ​​como ligeros ha aumentado en los últimos 40 años del mismo modo a como lo hicieron en un experimento anterior en el que se abonó el suelo del bosque. » El nitrógeno se origina en el interior de las estrellas gracias a temperatura y presión elevadas. En condiciones normales es incoloro, insípido e inodoro, y poco propenso a reaccionar con otras sustancias. En la atmósfera flota más del 75% del nitrógeno, que además es un componente esencial de las proteínas. Uno de los cambios que «activan» el nitrógeno viene producido por ciertas bacterias colonizadoras de raíces vegetales que extraen nitrógeno de la atmósfera y lo que significa o fijan en una forma útil para el crecimiento vegetal. Cuando las bacterias ya no necesitan el nitrógeno la planta lo absorbe, para luego pasar a los animales. La fijación del nitrógeno se define mediante el proceso de Haber, que convierte el proceso de nitrógeno gaseoso en amoníaco, un ingrediente común en los abonos. La fijación de nitrógeno por medios artificiales ha aumentado la cantidad de emisiones de nitrógeno reactivo en un 100%. Según los investigadores, el nitrógeno presenta dos formas o isótopos, átomos con la misma

Explanation:

The main difference between them is that bolus is more alkaline than chyme because it is exposed to alkaline saliva since food and drink are lowing the pH level of saliva.

The Bolus is considered as food and it is mashed up in our mouth and after that, it is turning into chyme which is digested food in our stomach.

Answer:

Water has a unique density. It is less dense as a solid than it is as a liquid, which is why ice floats on top of liquid water.

Explanation:

Answer: Water’s lower density in its solid form is due to the way hydrogen bonds are oriented as it freezes: the water molecules are pushed farther apart compared to liquid water. With most other liquids, solidification when the temperature drops includes the lowering of kinetic energy between molecules, allowing them to pack even more tightly than in liquid form and giving the solid a greater density than the liquid.

The low density of ice, an anomaly, causes it to float at the surface of liquid water, such as an iceberg or the ice cubes in a glass of water. In lakes and ponds, ice forms on the surface of the water creating an insulating barrier that protects the animals and plant life in the pond from freezing. Without this layer of insulating ice, plants and animals living in the pond would freeze in the solid block of ice and could not survive. The detrimental effect of freezing on living organisms is caused by the expansion of ice relative to liquid water. The ice crystals that form upon freezing rupture the delicate membranes essential for the function of living cells, irreversibly damaging them. Cells can only survive freezing if the water in them is temporarily replaced by another liquid like glycerol.

Answer:

B. Produces highly magnified images

Explanation:

Trust me

Kate and Sam are using a scanning electron microscope to study photosynthesis in algae, and the benefit of using this type of microscope rather than a light microscope is that the scanning microscope gives clearer details of the process.

The microscope gives a better view of the smaller things, and there are different types of microscopes, such as the light microscope, the electron microscope, etc., and other high-quality microscopes that are helpful for the better viewing of the samples. The light microscope has a lower magnification range than the electron microscope, and the species can be better viewed in the electron microscope. Depending on the application, different microscopes should be used, and photosynthesis can be seen better in a scanning microscope than in a light microscope.

Hence, the benefit of using this type of microscope rather than a light microscope is that the scanning microscope gives clearer details of the process.

Have a great day!!!

The factor that can decrease the rate of a chemical reaction is a low temperature.

A chemical reaction is the chemical transformation of one set of chemical substances into another.

A low temperature is one factor that can slow down a chemical reaction. A chemical reaction is defined as a process that transforms one set of chemical substances into another.

The rate of a chemical reaction is a measure of how quickly the reaction takes place.

A low temperature can slow down a chemical reaction by lowering the kinetic energy of the reacting molecules.

This means the molecules move slower and are less likely to collide with enough energy to break bonds and form new ones. As a result, the reaction rate slows down.

Thus, the answer is low temperature.

Answer:

Increase  ATP

Decrease NADPH

Decrease Sugar

Concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.

The concentrations of ATP,NADPH, and sugar decreases when you add paraquat because paraquat is a toxic chemical which blocks the activity of respiration in plants leading death of those plants. Paraquat inhibits the ATPase activity which is responsible for the production of ATP.

So due to no cellular respiration no ATP is produced. Paraquat (PQ) also inhibit photosynthesis so no glucose as well as NADPH is produced so we can conclude that concentrations of ATP, NADPH, and sugar decreases when we apply paraquat on the plants.

Explanation:

Answer:

Farmers were adding high nitrate levels from many large corn farms along the river. The farmers spray fertilizers that have ammonia and nitrate onto their crops. During the drought, the farmers used extra fertilizer. As rained, the ammonia and nitrate from the fertilizer were washed into the river.

In the pigs produced 10 pounds of feces that contained ammonia and nitrate. The pit is too small to obtain such large amount. When it rained the waste overflowed in to the river.

Explanation:

The drought from the week before and the large rain fall played a large part in the outcome of the annomia and nitrate exposure to water.

The farms upriver were adding to the high nitrate levels. It was because of the excessive use of fertilizers and inadequate waste disposal techniques.

There are chemicals that are used in agriculture. It includes fertilizers, pesticides, nematicides, insecticides, etc.

The farms upriver used to apply agrochemicals, especially the ones rich in nitrate and urea. During fewer water conditions they used to apply more. That used to remain in the soil and washed down to the river along with the rain.

The farms did not use adequate waste disposal measures and hence the wastes rich in nitrogen were washed down to the river.

Hence, these practices increase nitrate levels in the river.
