Glycemic Index

Explanation:

Glycemic index can be defined as the value assigned to the foods that is based on the criteria that how fast or slow the food can increase the blood glucose level.

Higher level of blood glucose can increase the chances of cardiovascular diseases and kidney failure.

A person who is suffering from diabetes must monitor his blood glucose level regularly.

Foods having low glycemic value tend to release glucose slowly into the blood and is good for the people suffering from diabetes. Foods having high glycemic value increases the blood glucose level very fast.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
