(A) Keratin

Hair is primarily composed of a protein called keratin. Keratin is a fibrous structural protein that forms the main component of hair, as well as nails and the outer layer of the skin. It provides strength and resilience to these structures. The other options—Casein, Globulin, and Mucin—are proteins found in other parts of the body and have different functions.

(C) Bulimia

Bulimia nervosa is an eating disorder characterized by binge eating, which involves consuming large amounts of food in a short period of time, often with a lack of control. Individuals with bulimia then engage in compensatory behaviors, such as vomiting, excessive exercise, or fasting, to prevent weight gain. The person described in the question, who does not know when to stop eating, may be exhibiting characteristics of binge eating, which is a key feature of bulimia. Diabetes, anorexia, and hyperacidity are different health conditions and not typically associated with an inability to stop eating in the described manner.

Tissues are groups of cells that are similar in origin, form, and function, working together to perform specific tasks in the body.

Each type of tissue is composed of cells that share common characteristics and collaborate to carry out specialized functions within the body.

According to Article 129, the Supreme Court acts as a court of record, that is, records are officially published and decisions are given on their basis, considering them as precedents.

(B) Urethra

The urethra is the structure that forms a common passage for both urine and sperm in human males. It connects the urinary bladder to the external opening and serves as the channel through which urine and semen pass out of the body. The other options—Oviduct, Ureter, and Vas deferens—are not involved in the passage of urine in males. Oviduct is part of the female reproductive system, while the ureter carries urine from the kidneys to the bladder, and the vas deferens is a duct that transports sperm from the testes to the urethra.
