[B] Insulin
[C] Glucagon
[D] Salt
Show Answer
Correct Answer: A [Glucose]
Notes:
The diabetic person has higher sugar in blood. Glucose is a form of water soluble sugar. Excess blood sugar decreases the elasticity of blood vessels and causes them to narrow, impeding blood flow. This can lead to a reduced supply of blood and oxygen, increasing the risk of high blood pressure and damage to large and small blood vessels.

[A] Pepsin
[B] Upes
[C] Trypsin
[D] Amaylase
Show Answer
Correct Answer: C [Trypsin]
Notes:
Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. It may also be referred to as a proteolytic enzyme, or proteinase. Trypsin is produced by the pancreas in an inactive form called trypsinogen. The trypsinogen enters the small intestine through the common bile duct and is converted to active trypsin.
40. The ____ helps in equalising the pressure on either sides of the eardrum:
[A] Malleus
[B] Incus
[C] Cochlear nerve
[D] Eustachian tube
Show Answer
Correct Answer: D [Eustachian tube]
Notes:
The eustachian tube is a canal that connects the middle ear to the nasopharynx. It controls the pressure within the middle ear, making it equal with the air pressure outside the body. The cochlear nerve is also known as the acoustic nerve. It transfers auditory information from the cochlea (auditory area of the inner ear) to the brain. The malleus transmits the sound vibrations from the eardrum to the incus, and then to the stapes.
