  1. Eyes

  2. Lungs

  3. Skin

  4. Bone marrow

Show answer
Correct Option: C
Explanation:
On exposure to radiation burns the skin first and then other biological tissue. The radiation can be ultraviolet light and ionizing radiation that causes sunburn. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns. As the ionizing radiation interacts with cells within the body damaging them, the body responds to this damage, resulting in erythema i.e., redness around the damaged area. Radiation burns are often associated with radiation-induced cancer due to the ability of ionizing radiation to interact with and damage DNA, occasionally inducing a cell to become cancerous.
Therefore, the correct answer is option C.

  1. Acromegaly

  2. Diabetes mellitus

  3. Diabetes insipidus

  4. Cushing's disease

Show answer
Correct Option: B
Explanation:

Acidosis is due to rapid fat catabolism. This leads to high levels of acetoacetic acid, which is converted to acetone and beta-hydroxybutyric acid. These three molecules known as ketone bodies. The presence of excreted ketone bodies in urine and in expired air is used as one diagnostic test for diabetes mellitus. Thus, the correct answer is option B.
