Answer: The transformation of energy from eating the meal to the five mile run is from
Chemical energy --> kinetic energy--> thermal energy.
Explanation:
In nature, energy exists in various forms. These forms are inter- convertible, that is, one form of energy can be transformed into another form. Such energy transformations are governed by the laws of thermodynamics.
The first law of thermodynamics states that energy cannot be created or destroyed but may be transformed from one form into another.
Living organisms which comprises the biotic components of an ecosystem are energy converters. For example:
--> plants convert solar energy into chemical energy during photosynthesis
--> animals convert chemical energy into kinetic energy when they move about. This in turn is lost as heat energy when highly complex organised food molecules are broken down.
From the question, the student ate a nutritious meal ( CHEMICAL energy) which is converted to KINETIC energy as she took a five miles run ( as she worked). 'Work' here refers not only to physical activities but also to the various metabolic processes necessary to maintain life. And each time work is done, kinetic energy is converted to heat( thermal energy)
A solution can be solid, liquid or gas. Hope I was able to help.
Answer:
Hi there!
A high salt intake has been shown to increase the amount of protein in the urine which is a major risk factor for the decline of kidney function.
In other words, taking in a lot of salt is not good news..
The alimentary canal includes mouth, esophagus, stomach, small intestine, and large intestine. As food passes through the alimentary canal, it is exposed to the different chemical secretions from the organs of the alimentary canal, as well as from other organs, such as liver and pancreas.
First, in the mouth, salivary glands produce saliva which contains enzymes involved in the food digestions. After the food is passed to the esophagus, it produces mucus to help passage of the food. In the stomach, acid and pepsinogen, as well as mucus are produced. All of these secretions help food digestion. Small intestine also produces some digestive enzymes. Further, bile from liver and enzymes from pancreas are secreted via ducts into small intestine. Finally, large intestine secretes mucus for lubrication.
Explanation:
An enlarged spleen can be caused by infections, cirrhosis and other liver diseases, blood diseases characterized by abnormal blood cells, problems with the lymph system, or other conditions. Other causes of an enlarged spleen include: Inflammatory diseases such as sarcoidosis, lupus, and rheumatoid arthritis.
