4. From which part, Coconut coir is obtained?
[A] Epicarp
[B] Mesocarp
[C] Endocarp
[D] Seed
Show Answer
Correct Answer: B [Mesocarp]
Notes:
Coir is the nature fibre obtained from mescocarp of the coconut fruit. Coconut fruit has three layers viz. Exocarp, MesoCarp and Endocarp. Exocarp is the outer green layer, Mesocarp is the fleshy, which becomes husk on drying middle layer and endocarp is the inner woody layer.
5. The hormonal activities of which of the following substances were discovered while studying “foolish seedling” disease in rice?
[A] Cytokinins
[B] Ethylene
[C] Auxins
[D] Gibberellin
Show Answer
Correct Answer: D [Gibberellin]
Notes:
The hormonal activities of Gibberellin were discovered while studying “foolish seedling” disease in rice. Gibberellins (GAs) are plant hormones. They regulate various developmental processes in plants.
6. Which one of the following is responsible for maintenance of osmotic pressure in blood?
[A] Fibrinogen
[B] Red Blood Cells
[C] Albumin
[D] Platelets
Show Answer
Correct Answer: C [ Albumin]
Notes:Albumin is a protein found in the blood plasma, and it plays a crucial role in regulating osmotic pressure. It helps to maintain the balance of fluids between the blood vessels and the surrounding tissues. Albumin exerts an osmotic pressure that prevents the excessive loss of fluid from the blood vessels into the tissues.
Fibrinogen, Red Blood Cells, and Platelets have different functions in the blood, but they are not primarily responsible for maintaining osmotic pressure. Fibrinogen is involved in blood clotting, Red Blood Cells are responsible for carrying oxygen, and Platelets play a role in blood clotting as well.
7. Which of the following sets is correctly paired in Taxonomy?
[A] Leech, Locust, Sea urchin, Lobster
[B] Star Fish, Jelly Fish, Cuttle Fish, Octopus
[C] Milliped, Crab, Centipede, Cockroach
[D] Round Worm, Earthworm, Flatworm, Silk worm
Show Answer
Correct Answer: C [Milliped, Crab, Centipede, Cockroach]
Notes:
The set Milliped, Crab, Centipede, Cockroach is correctly paired in Taxonomy, referring to the classification of these animals in their biological taxonomy. All belong to Arthropoda, the invertebrate group characterized by an exoskeleton, a segmented body, and jointed appendages. They hold a vast diversity of forms and have more species than any other animal phyla.
8. What is common to the techniques (i) in vitro fertilisation, (ii) Cryo preservation and (iii) tissue culture?
[A] All are in situ conservation methods
[B] All are ex situ conservation methods
[C] All require ultra modern equipment and large space
[D] All are methods of conservation of extinct organisms
Show Answer
Correct Answer: B [All are ex situ conservation methods]
Notes:
In vitro fertilisation, cryo preservation and tissue culture all are ex situ conservation methods. Ex situ conservation is a technique of conservation outside natural habitats.
9. ‘Pace-maker’ is associated with which of the following body organs?
[A] Liver
[B] Brain
[C] Heart
[D] Lungs
Show Answer
Correct Answer: C [Heart]
Notes:
A pacemaker is a small device that’s placed in the chest or abdomen to help control abnormal heart rhythms. This device uses electrical pulses to prompt the heart to beat at a normal rate.
10. What is study of fungus Known as?
[A] Mycology
[B] Phrenology
[C] Physiology
[D] Biology
Show Answer
Correct Answer: A [Mycology]
Notes:
Mycology is the branch of biology concerned with the study of fungi, including their genetic and biochemical properties, their taxonomy and their use to humans as a source for tinder, medicine, food, and entheogens, as well as their dangers, such as toxicity or infection.
