which activity results from the action of hydrochloric acid on protein in the stomach?
Answer:
Hydrochloric acid contributes to protein digestion by supplying H+ which activates pepsinogen, the precursor to pepsin. Pepsinogen is secreted by chief cells in the gastric glands of the body and antrum of the stomach
I hope this will be helpful
Activation of pepsin results from the action of HCl. Pepsin is important for the digestion of proteins. Thus, partial digestion of proteins happens in stomach.
What are the functions of stomach?Stomach has an important role in the digestion of food. It is regarded as organ for temporary food storage.
Stomach contains various digestive enzymes, gastric juice and hydrochloric acid that prepares the food for complete digestion in the duodenum.
The walls of the stomach secrete hydrochloric acid which is responsible for imparting acidity to food. It is also important for killing of any bacteria present in the food. The acidic pH activates the enzyme pepsin which is required for the digestion of proteins into peptones.
Stomach also contains the gastric juice which kills any microbes present in the food. It is also important for nutrient absorption. Stomach also contains enzyme lipase to favour partial digestion of lipids.
Thus, stomach is important for the partial digestion of proteins and lipids.

In mammals the digestive tract is made up of multiple
such as the stomach, pancreas and intestines. These all work together to form the
we use to digest food.
Answer:
The digestive system is made up of the alimentary canal (also called the digestive tract) and other organs, such as the liver and pancreas. The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus.
In mammals, the digestive tract is made up of multiple organs such as the stomach, pancreas, and intestines. These all work together to form the alimentary canal we use to digest food.
The digestive system in mammals is a complex network of organs and structures responsible for breaking down food into nutrients that can be absorbed and utilized by the body. The digestive tract, also known as the alimentary canal or gastrointestinal tract, consists of several organs that collaborate to facilitate the digestion and absorption process.
Stomach: The stomach is a muscular organ that receives and churns food, mixing it with gastric juices containing enzymes and acids to begin the process of digestion. It plays a crucial role in breaking down proteins.
Pancreas: The pancreas is both an endocrine and exocrine gland. Its exocrine functions involve producing digestive enzymes that are released into the small intestine to further break down carbohydrates, proteins, and fats.
Mouth: The mouth is where food is chewed and mixed with saliva. Saliva contains enzymes that start to break down carbohydrates.
Esophagus: The esophagus is a muscular tube that carries food from the mouth to the stomach.
Small intestine: The small intestine is the longest part of the digestive tract. It is where most of the nutrients from food are absorbed.
Large intestine: The large intestine is shorter than the small intestine. It absorbs water and salts from food and stores waste products until they are eliminated from the body.
Rectum: The rectum is the last part of the digestive tract. It stores waste products until they are eliminated from the body.
The digestive tract is a vital organ system that is essential for the survival of mammals. It allows mammals to obtain the nutrients they need from food to stay alive and healthy.

compare and contrast classical and operant conditioning
In classical conditioning, the involuntary response is seen, while operant conditioning is based upon the learning experience. An organism will perform more or less based on its experience with operant conditioning.
What are classical conditioning and operant conditioning?In classical conditioning, the stimulus is given and an involuntary response is observed. The Pavlov experiment on dogs is one example. He gave food to the dog and rang the bell at the same time for some days. After that, he only rang the bell, and the dog salivated without the food. Here, salvation is an involuntary response to the stimulus (bell ringing).
In operant conditioning, animals perform actions based on their experience. Example: A mouse is put in a box with an electric supply and food supply. When the mouse accidentally presses the electric switch, it gets an electric shock. This is negative reinforcement, and the mouse is less likely to perform the same function again. When it pushes the food lever, the food comes from the food box. This is positive reinforcement. The mouse is more likely to perform this.
Hence, in classical conditioning, the involuntary response is seen. Operant conditioning is based on learned experience.

What is Food?Food is a substance consisting essentially of protein, carbohydrate, fat, and other nutrients used in the body of an organism to sustain growth and vital processes and to furnish energy.
The absorption and utilization of food by the body is fundamental to nutrition and is facilitated by digestion.
Plants, which convert solar energy to food by photosynthesis, are the primary food source.
Animals that feed on plants often serve as sources of food for other animals.
What is Fuel?Fuel is a substance that is burned to provide nuclear energy, heat or power.
Materials like coal, wood, oil, or gas can provide heat when burned. Methanol, Gasoline, Diesel, Propane, Natural gas, Hydrogen are types of fuel. Nuclear energy is produced by burning plutonium.
From fuel efficiency or fuel economy, we can measure how long any vehicle could travel, which is the opposite of fuel consumption.
Fuel consumption is the amount of fuel vehicle uses to travel a particular distance.
Fuel efficiency can be measured in kilometers per liter. The efficiency with which the fuel does a conversion of energy is known as fuel efficiency.
