Answer: Esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.

Explanation:

La fotosíntesis es un proceso utilizado por las plantas y otros organismos fotoautótrofos para convertir la energía de la luz en energía química que, a través de la respiración celular, puede utilizarse para llevar a cabo distintas actividades metabólicas. Esta energía química se almacena en moléculas de carbohidratos, como los azúcares, que se sintetizan a partir de dióxido de carbono y agua. También se libera oxígeno como producto de desecho.

La energía de la luz es absorbida por unas proteínas llamadas centros de reacción que contienen pigmentos verdes de clorofila. En las plantas, estas proteínas se encuentran en el interior de unos orgánulos denominados cloroplastos, que son los más abundantes en las células de las hojas, mientras que en las bacterias están incrustadas en la membrana plasmática. En estas reacciones dependientes de la luz, se utiliza una parte de la energía para despojar de electrones a sustancias adecuadas, como el agua, produciendo gas oxígeno. El hidrógeno liberado por la ruptura del agua se utiliza en la creación de otros dos compuestos que sirven como almacenamiento de energía a corto plazo, permitiendo su transferencia para impulsar otras reacciones: estos compuestos son el nicotinamida adenina dinucleótido fosfato reducido (NADPH) y el adenosín trifosfato (ATP), la "moneda energética" de las células.

El almacenamiento de energía a largo plazo en forma de azúcares se produce mediante una secuencia posterior de reacciones independientes de la luz denominada ciclo de Calvin. En el ciclo de Calvin, el dióxido de carbono atmosférico se incorpora a compuestos de carbono orgánico ya existentes, como la ribulosa bifosfato (RuBP). Utilizando el ATP y el NADPH producidos por las reacciones dependientes de la luz, los compuestos resultantes se reducen y se eliminan para formar más carbohidratos, como la glucosa.  

Entonces, si el carbono en la molécula de dióxido de carbono (CO2) se encuentra marcada radiactivamente, esperaría encontrar la marca en el interior de moléculas de glucosa ya que el CO2, ya que se utilizan 6 moléculas de CO2 para sintetizar una molécula de glucosa.

Answer:

Divergent plate  

Explanation:

A semi ocean ridge is formed by the interaction of divergent boundaries. Around divergent plate boundaries, as additional sea floor is formed as the Earth's tectonic plates expand outward, half ridges form. Igneous material grows to the ocean bottom when the plates split, resulting in massive basalt volcanic activity.

Answer: D

Explanation:

Quantitative type of result the student calculate in this experiment.

Quantitative research is based on the collection and interpretation of numeric data. It focuses on measuring (using inferential statistics) and generalizing results.

The student have no hypothetical formula to calculate the actual strength of the web of both spider, so he always use to get quantitative type of result in his results.Hence option D is correct.

The history of Mount Rainier's eruptions can help you decide whether hiking around Mount Rainier is safe by providing information about the volcano's past activity, eruption patterns, and potential hazards.

The history of Mount Rainier's eruptions provides valuable insights into the volcano's behavior and can help assess the safety of hiking around the area. By studying the volcano's eruption history, scientists and authorities can gather data on the frequency, magnitude, and types of eruptions that have occurred in the past.

This information is crucial for understanding the potential hazards associated with the volcano. For example, if Mount Rainier has a history of frequent and large explosive eruptions, it may indicate a higher level of risk for hikers due to the potential for ashfall, pyroclastic flows, or lahars (volcanic mudflows) that can pose dangers to human life.

Additionally, analyzing the timing and recurrence intervals of past eruptions can help estimate the likelihood of future eruptions. If the volcano has been relatively inactive for an extended period, it may suggest a lower immediate risk for hikers. However, it is essential to consider the potential for future eruptions and monitor any signs of volcanic unrest or changes in activity.

Furthermore, studying the extent and distribution of past volcanic deposits, such as lava flows or ash layers, can help identify areas that are more prone to hazards. This information can be used to establish exclusion zones or restrict access to certain hiking trails that may be closer to potential hazards.

Ultimately, by considering the history of Mount Rainier's eruptions and the associated hazards, authorities can make informed decisions regarding the safety of hiking around the volcano. It is crucial for hikers to stay updated with the latest information from local authorities, volcanic monitoring agencies, and park management to make responsible choices and ensure their safety when exploring the area.

Answer:

D) carbon dioxide

Explanation:

Carbon dioxide (CO2) is the most important greenhouse gas which is known to absorb heat that would otherwise be lost to space. It has been shown that CO2 causes approximately 80% of global warming. Different human activities, but especially the burning of fossil fuels, are the main cause of global warming. It has been estimated that 40 billion metric tons of CO2 produced by human activities are being discharged into the atmosphere annually. Other human activities associated with global warming by increasing the concentration of CO2 in the atmosphere include deforestation and cement production.
