Answer:
The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".
Explanation:
A chemical change is one which is not easily reversible and which results in the formation of new subsatances.
For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.
From explanations provided by the students :
Luke does not give any explanation of the process but only an observation
Jackie's explanation does not state the main reason why a chemical change differs from a physical one.
Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.
Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.
Answer:
Type II diabetics have normal to elevated levels of insulin. What, then, might be causing their elevated blood glucose levels? B) defective receptors
Explanation:
Type II dabetics is known as the most common type in adults. In this type, people have normal to elevated levels of insulin. It is related to some other pathologies such as obesity, over weight, stress. <em>Type 2 diabetes is due to defective receptors. There is insuline in muscles, liver and fat tissues. This resistence shows the inhability of cells to respond to normal levels of glucose, elevating blood glucose levels.</em>
