The insulin receptors have specific shape that is compatible to the glucose molecules. The glucose molecules bind to these receptors, which tells the pancreas to release insulin in order to lower the blood glucose level. Any kind of change in the shape of these receptors because of mutation will hinder this cell communication and stop the insulin release. This will lead to high levels of blood sugar level.
Correct answer: D) From bacteria living in their roots
Nitrogen is an essential plant nutrients, but it is metabolically unavailable to higher plants and animals. It is available to some species of microorganism by biological nitrogen fixation in which nitrogen is converted to ammonia with the help of enzyme dinitrogenase.
The process of breaking apart the two atoms in a nitrogen molecule is called nitrogen fixation. Plant obtain the nitrogen they need from the soil which is already fixed by the bacteria and archae.
Example: <em>Azobacter</em><em>,</em> Nostac
