Answer: The second image best represents the relationship of the concentration of hydrogen ions between water, vinegar and ammonia.
Explanation: pH is the measure of alkalinity and acidity of a substance in a logarithmic scale.
Mathematically,
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
The solutions which lie in the pH range of 0 - 6.9 are considered as acidic solutions and they have more hydrogen ion concentration.
The solution which has a pH value of 7 is considered as a neutral solution and this solution has same hydrogen and hydroxide ion concentration.
The solutions which lie in the pH range of 7.1 - 14 are considered as basic solutions and they have less hydrogen ion concentration.
- For vinegar, the hydrogen ion concentration is very high.
- For water, the hydrogen ion concentration will be equal to the hydroxide ion concentration.
- For ammonia, the hydrogen ion concentration is very less.
Answer:
Explanation:
When you exhale, the diaphragm relaxes and the air is pushed out of lungs. It also has some nonrespiratory functions as well. The diaphragm increases abdominal pressure to help the body get rid of vomit, urine, and feces. It also places pressure on the esophagus to prevent acid reflux.

The theory of evolution provides a number of insights:
-it tells us how the species are related
-it tells us how the species and populations react to the changes in their environment
With this knowledge, the scientists can predict how the species will react to the potential changes and support the positive changes (provide a good environment for the animals for example) <span />
The clinical manifestation which supports this conclusion is that an injury to the brachial plexus which happens during birth. Erb is termed as a paralysis of the arm which is caused by an injury on upper arm's main nerves to be specifically the C5-C6 nerves.
It arrives most commonly on shoulder dystocia when there is a difficult birth. This paralysis can resolve on its own depending on nature of the damage.
The movement of food through the esophagus is called peristalsis.
<h3>What is the buccal cavity?</h3>
The mouth is what we generally call the buccal cavity. It is an opening that contains the teeth and the tongue. The tongue plays the important role of serving as the organ of taste while the teeth serves to marsh food. It is the white strong structure that occurs in the mouth that enables is to masticate our food. Also in the mouth we have the salivary gland which plays the role of secreting the saliva and we know that the saliva contains from enzymes that makes it possible for the digestion of food to commence at the moth. It the follows that the buccal cavity is made up of the teeth, tongue and salivary glands.
Food moves into the stomach via the esophagus. Thus movement is slow and is aided by the muscles that line the gastro intestinal tract. As such, movement of food through the esophagus is called peristalsis.
