Answer:
The question as the options lacking but based on the question we can infer the ANSWER
Based on the results of the experiment we can best say that urea will disrupt the function of the certain enzyme and that when the urea is removed the enzyme regained its function.
Explanation:
Denaturation is the term used to describe urea effect on the enzymes as it inactivates it by affecting it's secondary and tertiary function. In the process it’s 3D structural conformation is altered.
Answer:
<h2>
potassium</h2>
Explanation:
The heartbeats of the heart are controlled by the sinoatrial node also known as the pacemaker of the heart. The impulse is generated in the conducting cells of the pacemaker as a result of the movement of sodium, potassium and calcium ions.
The sodium channels allow the movement of sodium into the cell which depolarizes the membrane from -60mv to -40 mv. At this point, the calcium gated channels open which allow the entry of the calcium in the cell which depolarizes the cell up to +5mv.
At this point, the potassium channels open which allows the potassium ions to move out of the cell. This repolarizes the cell and hence the cycle again begins. Reducing the permeability of the potassium ions help generate the autorhythmicity due to repolarization and thus is the correct answer.
Answer:
Air pollution would most likely trigger climates change.
Explanation:
Poor air quality can lead to fires, diseases, and higher air temperature
