Homeostasis maintains a stable internal environment in organisms through feedback mechanisms. An example of a feedback mechanism is the regulation of blood glucose levels. If homeostasis fails, diseases such as diabetes may emerge.
Homeostasis is the process where an organism maintains a stable internal environment, which is crucial for survival. This stability is achieved through feedback mechanisms. These mechanisms monitor and adjust various biological systems within the body to maintain balance.
One example of a feedback mechanism in the human body is the regulation of blood glucose levels. When blood glucose levels rise, the pancreas produces insulin, which promotes the uptake of glucose into cells, reducing blood glucose levels. This is an example of a negative feedback mechanism because the effect of the response to the stimulus is to reduce the original stimulus. Conversely, if blood glucose levels fall, the pancreas produces glucagon, which prompts the liver to release stored glucose, thus increasing blood glucose levels.
If homeostasis fails in the human body, one specific result, beside death, could be the emergence of diseases such as diabetes. If the feedback mechanism for regulating blood glucose levels is impaired and the body doesn't produce enough insulin or the body's cells resist the effects of insulin, the result is high blood sugar and diabetic conditions.

Answer;
-Mitochondria
Explanation;
-Viruses are small infectious agents that replicates only inside the living cells of other organisms. Some of the features of viruses includes;
-They are enclosed in a protective envelope.
-They have spikes, which helps them to attach to the host cell.
-They are non cellular.
-They do not respire, do not metabolize and do not grow but they do reproduce.
-They contain a protein coat called the capsid.
-They have a nucleic acid core containing DNA or RNA.
