A.
DDT
B.
Gambusia
C.
Oil
D.
Ointments
Ans:
Gambusia
Explanation :
Biological control is the use of natural enemies to manage the mosquito population. Effective biocontrol agent s include predatory fish that teed on mosquito larvae such as Gambusia affinis (mosquitofish) and some cyprinids (Carps and minnows).
[18] Haemophilia is a genetic disorder which leads to -
A.
decrease in haemoglobin level
B.
rheumatic heart disease
C.
decrease in WBOC
D.
non-clotting of blood
Ans:
non-clotting of blood
Explanation :
Haemophilia is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding.
[19] In eye donation, which one of the following parts of donor's eye is utilized?
A.
Iris
B.
Lens
C.
Cornea
D.
Retina
Ans:
Cornea
Explanation :
Generally blindness is caused by the dryness and hardness of cornea. Cornea is a clear layer which helps passing of light. It is an outer layer and can be transfer from one person to another.
[20] Blood is a:
A.
connective tissue
B.
epithelial tissue
C.
muscular tissue
D.
reproductive tissue
Ans:
connective tissue
Explanation :
Blood is considered a connective tissue for two basic reasons: (i) embryologically, it has the same origin (mesodermal) as do the other connective tissue types and (ii) blood connects the body systems together bringing the needed oxygen, nutrients, hormones and other signaling molecules, and removing the wastes.
[21] The natural disaster in which carbon-dioxide suddenly erupts from a deep lake water is known as .
A.
Lacaustrine
B.
Fluvial
C.
Glacial
D.
Liminic
Ans:
Liminic
Explanation :
A limnic eruption, also referred to as a lake overturn, is a rare type of natural disaster in which dissolved carbon dioxide (CO2) suddenly erupts from deep lake water, suffocating wildlife, livestock and humans. Such an eruption may also cause tsunamis in the lake as the rising CO2 displaces water.
[22] Conglobate gland is a leaf like structure found in -
A.
Female Cockroach
B.
Male Cockroach
C.
Male Ascaris
D.
Female Ascaris
Ans:
Male Cockroach
Explanation :
Conglobate gland is a leaf like, median, unbranched gland of male cockroach. It lies below the ejaculatory duct and open into the genital pouch close to the male genital aperture.
[23] In the resistance colour code, the fourth band signifies -
A.
tolerance level
B.
power of ten
C.
the total value of resistance
D.
the material of the resistor
Ans:
tolerance level
Explanation :
The first and second band represent the numerical value of the resistor, and the color of the third band specify the power-often multiplier. Reading the resistor from left to right, the fourth band represents the tolerance.
[24] The curcumin is isolated from -
A.
Gallic
B.
Turmeric
C.
Sunflower
D.
Rose flower
Ans:
Turmeric
Explanation :
Curcumin is a natural component of the rhizome of turmeric (Curcuma longa) and one of the most powerful chemopreventive and anticancer agents.
[25] Teeth and Bones acquire strength and rigidity from -
A.
Calcim
B.
Fluorine
C.
Chlorine
D.
Sodium
Ans:
Calcim
Explanation :
The human body requires more calcium than any other mineral. At least 99% of the calcium is found in the bones and teeth, giving them strength and rigidity.
Explanation :
Biological control is the use of natural enemies to manage the mosquito population. Effective biocontrol agent s include predatory fish that teed on mosquito larvae such as Gambusia affinis (mosquitofish) and some cyprinids (Carps and minnows).
