Mechanical stress applied to bone increases osteoblast activity in bone tissue, and the removal of mechanical stress decreases osteoblast activity.
Explanation:
Osteoblasts are cells , that are produced in the bone marrow and are responsible for formation of bones and bone matrix.
Whenever a mechanical stress is applied on the bones , a series of reactions are triggered. As a result the activities of osteoblast increases to synthesize more and more bone matrix to provide strength.
Again on the other hand a decrease in mechanical causes a decrease in the activities of the osteoblasts.
Diabetes type 1 is a chronic illness also referred to as juvenile diabetes or insulin-dependent diabetes.
<h3>
What is type-I Diabetes?</h3>
- The pancreas produces little or no insulin in this situation. Insulin is a hormone that the body utilizes to let glucose (sugar) into cells where it can be used to make energy.
- Type 1 diabetes may be brought on by a variety of factors, including genetics and some viruses. While type 1 diabetes typically first manifests in childhood or adolescence, it can also strike adults.
- There is still no cure for type 1 diabetes, despite much research. The goal of treatment is to prevent problems by controlling blood sugar levels with the use of insulin, food, and lifestyle changes.

We know that arteries from the aorta and arteries from coronary arteries supply oxygenated blood to various parts of the body. What separates these two is the coronary arteries’ ability to deliver oxygenated blood to the heart.
We know that the inferior vena cava delivers deoxygenated blood to the lower (hence inferior) part of the body and that the superior vena cava delivers deoxygenated blood to the upper (superior) part of the body; they follow the same deoxygenated rule and strictly deliver nutrients to certain parts of the body.

This is extremely vague, but assuming this is regarding concentration gradient in the nervous system, the Sodium-Potassium pump is responsible for transporting sodium and potassium.
