The correct answer among the choices listed above is option C. The amount of carbon dioxide in the atmosphere has <span>increased</span> since industrialization began in the nineteenth century. This is because more carbon dioxide is emitted by machines in plants and by the vehicles.
Wild Bedbugs become insecticide resistant because of the mutations and natural selections.
<h3><u>Explanation</u>:</h3>
As the huge amount of pesticides and insecticides are sprayed in the rooms for cleaning, the pests and insects like bedbugs dies in huge portions because of the toxin. But some of the bedbugs remain alive as they have mutations that help them to detoxify the toxins given, or bypass the metabolic processes so that the toxins don't hamper them much.
Now as the population becomes very small(bottle neck effect), the nature selects these organisms over the other to propagate more sufficiently and enormously. As the nutrients and supplies are also available, so the bedbugs don't suffer any lack of nutrition which can be a determining factor of their population.
Thus the wild bedbugs become resistant to insecticides while the experimental one remain succeptible to insecticides.
<span>During nitrification, ammonia is changed back into nitrate.</span>
Nitrification is a three-step process of oxidation of ammonia. It is an aerobic process performed by small groups of autotrophic bacteria (<span>Nitrosomonas,
Nitrobacter</span>).
First step- ammonia to hydroxylamine,
Second step-hydroxylamine to nitrite,
Third step-nitrite to nitrate.
Nitrification together with ammonification is part of a nitrogen cycle.
Answer is: when the carbon atoms of the glucose molecule are broken apart in glycolysis and the Krebs cycle, result is a. CO2 and ATP.
In Krebs cycle aerobic organisms release stored energy through the oxidation of acetyl-CoA derived from glucose into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP).
