Answer:
<em>The valid conclusion is:</em>
- <u><em>D. the temperature of the object is increasing, while the temperature of the water is decreasing</em></u>
<u><em></em></u>
Explanation:
The answer choices are:
- <em>A. the temperature of the object is decreasing, while the temperature of the water is increasing</em>
- <em>B. the temperature of the object is decreasing, while the temperature of the water is decreasing</em>
- <em>C. the temperature of the object is increasing, while the temperature of the water is increasing</em>
- <em>D. the temperature of the object is increasing, while the temperature of the water is decreasing</em>

<h2>Solution</h2>

Thermal or heat energy always flows from the hotter substances to the cooler substances.
Thus, since the arrows show that the thermal energy is flowing from the water to the object, the water is losing thermal energy and the object is gaining thermal energy.
When an object gains thermal energy, and there is not involved a change of phase, the temperature of the object increases. Thus, the temperature of the object is increasing.
On the other hand, since water is losing thermal energy, and there is not involved a change of phase, the temperature of the water decreases.
Therefore, the correct conclusion is described by the option A:
- <em>A. the temperature of the object is decreasing, while the temperature of the water is increasing</em>
Answer:
Glucose
Explanation:
Glucose, also called dextrose is one of a group of carbohydrates known as simple sugars or monosaccharides. Glucose is derived from the Greek word 'glykys' meaning “sweet”. It has the molecular formula C6H12O6. It is commonly found in fruits and honey and is the major free sugar circulating in the blood of higher animals. It is the source of energy in cell function, and the regulation of its metabolism is of great importance. Molecules of starch, the major energy-reserve of carbohydrate of plants, consist of thousands of linear glucose units. Another major compound composed of glucose is cellulose, which is also linear. Dextrose is the molecule D-glucose.
Glucose is composed of carbon hydrogen and oxygen in a ratio of 1:2:1 as typified by its formula. It is known for its sweet taste. It can be combined with fructose in table sugar.
