During the light-independent reaction, carbon dioxide is fixed by adding it to a 3-carbon compound
Answer: Option B
<u>Explanation:</u>
In the first stage of ''Calvin cycle'', light independent reactions are started and the carbon dioxide gets fixed from a molecule that does not have light to a molecule having light and in the second stage where carbon compound like ATP and NADPH gets reduced into a three carbon compound. This is done for converting energy in to a chemical bond energy for example in a glucose.
Answer:
polar region
High latitudes are dominated by floating sea ice covering much of the Arctic ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica in the South.
It is a false statement that the <span>Appalachians, the oldest North American mountains, are an example of upwarped mountains. The correct option among all the options that are given in the question is the second option. The Appalachians are examples of folded mountains. I hope the answer has helped you.</span>
In April of 1869, he obtained a patent for one of his most important inventions, the air brake. This device enabled trains to be stopped with fail-safe accuracy by the locomotive engineer for the first time and was eventually adopted on the majority of the world's railroads
Answer: The ice has been melting and declining
Explanation:
Due to an increase in industrialization, global warming is occurring. This has increased the average temperature around the globe considerably.
As you probably know, ice needs to be in a cold environment to stay frozen. <em>Arctic sea ice</em>, which is ice that floats in the sea near the Arctic, <em>has been </em><em>melting</em> due to global warming.
In addition, the land ice on Antarctica and Greenland has <em>also been </em><em>melting</em> due to global warming. The increase in average temperatures around the globe has created an environment that is <em>too warm</em> for ice.
In conclusion, <em>global warming</em> has caused Arctic sea ice, and land ice on Antarctica and Greenland, to <em>melt</em>. The globe <em>is warmer than it once was</em>. This means that the water that once was frozen is now melting. If we don't stop heating the planet, <em>sea levels will rise </em>due to the melting ice, and catastrophe will occur. Tens of thousands of animals will die, homes will be lost, and storms will increase in intensity and frequency if we don't reverse the effects of global warming <u><em>now.</em></u>
Save the Arctic, please.
