The correct answer is: Heartburn often results when the gastroesophageal sphincter fails to close properly.
The gastroesophageal sphincter is a muscle located at the bottom of the esophagus that has to be relaxed in order to allow food to flow down into the stomach. After it contracts (tightens), the food and the stomach acid can’t flow back up into the esophagus.
When the gastroesophageal sphincter fails to close properly acid reflux occurs and causes the heartburn.
I believe the primary structure will be preserved. The secondary level of proteins is defined by patterns of hydrogen bonds between the main chain peptide groups. Therefore distorting the Hydrogen bonds disrupts the secondary structures. The primary structure on the other hand is not affected by disruption of the hydrogen bond since these structures refers to the sequences of amino acids in the polypeptide chains that are joined by the peptide bonds.
Agriculture is an activity that requires a lot of fresh water.
- This is because agricultural crops need large amounts of water to grow and remain productive.
- In a situation of large-scale agricultural production, this need for water is even greater, causing producers to use large quantities of water that is necessary for the consumption of the population.
<h3>Give the detailed explanation?</h3>
In order to conserve fresh water and keep it at high quality levels to be used both in agriculture and for human consumption, it is necessary that agricultural producers allow the maintenance of riparian forests, use more biodegradable pesticides or with low impact on nature and pay attention to irrigation equipment to avoid waste.
In addition, many producers waste water and pollute it with an excess of pesticides and deforestation.
