(a) Insulin / इंसुलिन
(b) Adrenaline / एड्रेनालाईन
(c) Estrogen / एस्ट्रोजेन
(d) Oxytocin / ऑक्सीटोसिन
Show Answer
Ans.(b)
Sol. Adrenaline is commonly known as the ‘fight or flight hormone’. Adrenaline is a hormone released from the adrenal glands and its major action together with nor-adrenaline is to prepare the body for fight of flight. Adrenaline (Epinephrine) causes dilation of blood vessels (Vasodilation) which supply the brain, skeletal muscles, heart, lungs, liver, adipose tissues, sensory organs etc. Due to increased blood supply. These organs become very active and excited inducing alarm reaction, contraction of cardiac muscles intensify, increasing both rate and force of heartbeat, pulse rate, arterial pressure and cardiac output.

Ans.(a)
Sol. The liver is the largest internal organ and the largest gland in the human body. While thyroid gland is largest endocrine gland in the body. The liver is 25 cm long; 15 cm wide is a reddest brown gland, weighing about 1.5 kg. It plays an active role in the process of digestion of fats, carbohydrate through the production of bile.

(c) Pancreas / अग्न्याशय
(d) Pituitary / पिट्यूटरी
Show Answer
Ans.(d)
Sol. The pituitary gland is the smallest gland in the human body which sits in a bony hollow called the pituitary fossa. Its weight is between 0.5-1.0 gram and diameter is 1-15 cm. It is famous as ‘Master gland’ because most of its hormones control the activity levels of other endocrine glands. It is also called hypophysis cexibrai.

Q14. The gas used in the artificial ripening of green fruit is:
हरे फलों को कृत्रिम रूप से पकाने में किस गैस का उपयोग किया जाता है?
(a) Acetylene / एसिटिलीन
(b) Ethane / एथेन
(c) Hydrogen/ हाइड्रोजन
(d) Carbon dioxide/ कार्बन डाइऑक्साइड
Show Answer
Ans.(a)
Sol. Under prevention of food adulteration rule, 1955 (Act 44AA) acetylene gas can not be used in the ripening of fruits. Calcium carbide is used in some countries as a source of acetylene gas, which is an artificial ripening agent. However, acetylene is not nearly as effective as ethylene and is not a natural plant hormone-like ethylene. Also, calcium carbide may contain traces of arsenic and phosphorus, both highly toxic to humans and the use of this chemical for ripening is illegal in most countries. Ethylene has been found not harmful or toxic to humans in the concentrations found in ripening rooms.
