Final answer:
To study the impact of abnormally high blood-sugar levels on cellular homeostasis in diabetics, a researcher can explore how high blood-sugar levels affect cellular homeostasis and the specific changes in cellular processes that occur in diabetics.
Step-by-step explanation:
To study the impact of abnormally high blood-sugar levels on cellular homeostasis in diabetics, a researcher can explore the following question: How does high blood-sugar levels affect cellular homeostasis in diabetics and what are the specific changes in cellular processes that occur?
By focusing on the specific cellular changes caused by high blood-sugar levels in diabetics, the researcher can gain insights into the mechanisms underlying the disruption of homeostasis, potential cellular damage, and the development of complications associated with diabetes.
This study would fall under the subject of Biology and is suitable for High School level.
