X-rays
used to measure bone density.
<u>Explanation</u>:
The bones density test measured by the X-rays, it measures the content of calcium and other bone minerals that are packed into the segment of bone. Most commonly used parts of bone for testing are spine, hip, occasionally and the forearm. It is generally done to know the chances of osteoporosis. More the bone minerals, more will be density. More density means the higher bone strength. Before the test, a person should avoid having calcium supplement.
Answer: The correct answer to the question is option D
SPACE OBSERVATORY
SPACE OBSERVATORY uses electromagnetic radiation to discover the properties and composition of bodies in space.
Explanation: A space observatory (Example; Telescope) is simply an instrument that is used to observe distant galaxies, stars, planets and other objects in the outer space.
Findings from space observatory enhances our knowledge of the COSMOS as they can be recorded for after study.
An adrenal gland can develop an uncommon, often benign (noncancerous) tumor called a pheochromocytoma.
- A (pseudo)hypoxic signature is seen in many solid tumors, such as paraganglioma (PGL) and pheochromocytoma (PHEO). It has been demonstrated that (pseudo)hypoxia encourages the development of tumors and therapeutic resistance.
- Hypoxia-inducible factors (HIFs) are the main mediators of the transcriptional hypoxic response.
- The transcription of hypoxia-responsive genes, which are involved in cancer, is induced by high levels of HIFs. Catecholamine-producing tumors called PHEOs and PGLs develop from sympathetically or parasympathetically generated chromaffin tissue.
- HIF signaling appears to be crucial for the growth and development of PHEOs and PGLs, which may point to novel therapeutic strategies for the management of these malignancies.
