Answer:
Bacteria
Explanation:
Bacteria have no true nucleus because it's a prokaryote. It couldn't have been a virus because all naturally occurring viruses are pathogenic unless treated by radiation.
We have two types of bacteria,
- Pathogenic
- Commensals
Pathogenic bacteria will definitely cause disease. Commensals, however, have don't harm us and have the ability to help us.
Eg: Flora (bacteria) in our intestines produce vitamin K and most of the vitamin B complex. They also compete with the pathogenic bacteria that you might've ingested and don't allow them to increase to the number that can cause disease.
These products are designed to coat the gastric tissues and protect it from the acidity of the stomach or gastric secretions.
<h3>What are Pepto Bismol and Milk of Magnesia?</h3>
Pepto Bismol is made up of mainly Bismuth subsalicylate which has the ability to coat the mucosal surface of the gastric tissues.
Milk of Magnesia contains antacid that helps reduce the acidity of the stomach.
Therefore Pepto Bismol and Milk of Magnesia can be taken when people have an upset stomach.

Answer:
D. The process requires energy that is provided by ATP.
Explanation:
Neurons use a pump called the sodium-potassium pump, which normally pumps sodium ions out of the cell and pumps potassium ions into the cell.
This pump goes against the concentration gradient to create the resting membrane potential.
Since the pump goes against the concentration gradient, it requires energy, because it is not passive diffusion.
So, D is the correct answer, as the process requires ATP energy.
