Answer: b Explanation:
In the ripening process, tomatoes change their color from green to yellowish and finally turn to full red colour. This gradual change in tomato color is mainly because of chlorophyll breakdown. The carotenoid especially lycopene is the main compound that provides red color to tomatoes. This compound is synthesized as a result of the breakdown of chlorophyll during ripening.
This compound also provides red color to other fruits and vegetables which include watermelons, red oranges, pink grapefruits, apricots, rosehips, guavas, carrots, and yellow sweet potatoes.
Lycopene is an organic compound that is insoluble in water but can be dissolved in organic solvents. Hence, if you keep tomato sauce in plastic plates or bottles for some time, then it is absorbed into them and turns them into orange colour.
Answer: 2. Single cell. Explanation: Both amoeba and unlaid chicken eggs belong to the common category such as single cell. Alone, amoeba relates to two options, organism and single cell. However, the unlaid chicken egg relates to only one option, single-cell because it has no complete life at thisRead more
Answer: 2. Single cell.
Explanation:
Both amoeba and unlaid chicken eggs belong to the common category such as single cell. Alone, amoeba relates to two options, organism and single cell. However, the unlaid chicken egg relates to only one option, single-cell because it has no complete life at this stage. Hence the answer is 2.

Answer
The stomach acid mainly hydrochloric acid is a part of gastric juice (a fluid substance that contains all digestive enzymes, HCl, and other substances). The gastric juice is produced by stomach cells. The acidic nature of gastric juice is mainly due to hydrochloric acid. In our stomach, food is churned and broken down into smaller parts and mixed with gastric juice.
The enzymes and acid in the gastric juice partially digest the consumed food materials. The main enzymes of gastric juice include lipase and pepsin.
The functions of hydrochloric acid in our stomach:
The production of HCl by the stomach plays a crucial role in the digestion of food.
Gastrin is a peptide hormone that induces the secretion of stomach acid (HCl) by the stomach’s parietal cells and is also involved in gastric motility.
The acidic environment created by HCl is very crucial for enzymatic digestion.
Hydrochloric acid also plays an integral role in protecting the body from pathogens which are emerged through consumed food or water. If stomach acid levels are drop to pH.3, then there will be significant colonization of bacterial pathogens.
What happens if the acids are absent in your stomach?
The underproduction of hydrochloric acid (low levels of HCl) in the stomach is considered as the body’s abnormality, the condition is called hypochlorhydria.
In hypochlorhydria conditions, the body compromises the gastric barrier (a natural defense against microbes) and favors microbial growth in the small intestine, which resulted in the development of various bacterial infections.
Lower levels of gastric acid are also hinder the absorption of iron.
The enzymes pepsin and lipase are dependent on the acidic environment for their enzymatic activity. The deficiency in acid production in the stomach also leads to digestion problems.
Moreover, the lower levels of HCl in the stomach stimulates the production of more amount of the gastrin hormone, a condition is called hypergastrinemia.
