[10] An example of false fruit is -
A.
Apple
B.
Guava
C.
Mango
D.
Tomato
Ans:
Apple
Explanation :
An accessory fruit (sometimes called false fruit, spurious fruit, pseudofruit, or pseudocarp) is a fruit in which some of the flesh is derived not from the ovary but from some adjacent tissue exterior to the carpel. Examples of accessory tissue are the receptacle of strawberries, figs, or mulberries, and the calyx of Gaultheria procurribens or Syzygium jambos. Pomes, such as apples and pears, are also accessory fruits, with much of the fruit flesh derived from a hypanthium. Fruit with fleshy seeds, such as pomegranate or mamoncillo, are not considered to be accessory fruit.
[11] The green colour of the leaves is due to the presence of -

[20] The animal which can tolerate more summer heat is -
A.
Buffalo
B.
Cow
C.
Goat
D.
Donkey
Ans:
Goat
Explanation :
Some livestock (and people) tolerate heat better than others. Sheep and goats tend to be less susceptible to heat stress than swine, cattle, llamas, and alpacas. Hair sheep usually tolerate heat better than wooled sheep. This is why they are often used for training and trialing herding dogs. Fat-tailed sheep are also more heat tolerant. The European sheep breeds are usually the least heat-adaptive because they tend to have shorter bodies and legs, short, thick ears, tight skin, and dense fleeces.
[21] Ringworm is a disease.
A.
Bacterial

Explanation :
Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term "ringworm" is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors. In pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs.

A.
Altmann
B.
Landsteiner
C.
Losch
D.
Ronald Ross
Ans:
Landsteiner
Explanation :
Karl Landsteiner was an Austrian biologist and physician. He is noted for having first distinguished the main blood groups in 1900, having developed the modern system of classification of blood groups from his identification of the presence of agglutinins in the blood, and having identified, with Alexander S. Wiener, the Rhesus factor, in 1937, thus enabling physicians to transfuse blood without endangering the patient's life. With Constantin Levaditi and Erwin Popper, he discovered the polio virus, in 1909.

A.
4 - 6
B.
2 - 4
C.
8 - 10
D.
12 - 16
Ans:
4 - 6
Explanation :
Oxygen is one of several dissolved gases important to aquatic systems. Dissolved oxygen is necessary to maintain aerobic conditions in surface waters and is considered a primary indicator when assessing the suitability of surface waters to support aquatic life. For maintenance of aquatic health, dissolved oxygen concentrations should approach saturation - that concentration which is in equilibrium with the partial pressure of atmospheric oxygen.
[10] An example of false fruit is -
A.
Apple
B.
Guava
C.
Mango
D.
Tomato
Ans:
Apple
Explanation :
An accessory fruit (sometimes called false fruit, spurious fruit, pseudofruit, or pseudocarp) is a fruit in which some of the flesh is derived not from the ovary but from some adjacent tissue exterior to the carpel. Examples of accessory tissue are the receptacle of strawberries, figs, or mulberries, and the calyx of Gaultheria procurribens or Syzygium jambos. Pomes, such as apples and pears, are also accessory fruits, with much of the fruit flesh derived from a hypanthium. Fruit with fleshy seeds, such as pomegranate or mamoncillo, are not considered to be accessory fruit.
[11] The green colour of the leaves is due to the presence of -
A.
Proteins
B.
Lipids
C.
Chlorophyll
D.
Carbohydrates
Ans:
Chlorophyll
Explanation :
The green color in leaves is caused by the presence of a compound called "chlorophyll," which the plant produces to do photosynthesis, which is how plants get energy from sunlight. The purpose of chlorophyll is to assist the plant in making food for itself by utilizing energy from sunlight and nutrients from the soil. The chlorophyll is green because it absorbs red and blue wavelengths of light — and so green is not absorbed and is reflected, making the plant look green to our eyes.

The edible portion in an onion is swollen leaves with a bit of stem. They are bulbs which, like garlic and leeks, are modified stems in which the primary storage tissue is expanded leaf bases. They come in white, yellow, and red varieties.
[13] Haemophilia is mostly associated with -
A.
Labourers
B.
Royal families
C.
Miners
D.
Sportsmen
Ans:
Royal families

B.
97.4 °F
C.
98.4 °F
D.
99.4 °F
Ans:
98.4 °F
Explanation :
The normal core body temperature of a healthy, resting adult human being is stated to be at 98.6 degrees Fahrenheit or 37.0 degrees Celsius. Though the body temperature measured on an individual can vary, a healthy human body can maintain a fairly consistent body temperature that is around the mark of 37 degrees Celsius. The normal range of human body temperature varies due to an individual's metabolism rate, the higher (faster) it is the higher the normal body temperature or the slower the metabolic rate the lower the normal body temperature.
[18] Normal fasting blood sugar level per 100 ml. of blood in man is -

[20] The animal which can tolerate more summer heat is -
A.
Buffalo
B.
Cow
C.
Goat
D.
Donkey
Ans:
Goat
Explanation :
Some livestock (and people) tolerate heat better than others. Sheep and goats tend to be less susceptible to heat stress than swine, cattle, llamas, and alpacas. Hair sheep usually tolerate heat better than wooled sheep. This is why they are often used for training and trialing herding dogs. Fat-tailed sheep are also more heat tolerant. The European sheep breeds are usually the least heat-adaptive because they tend to have shorter bodies and legs, short, thick ears, tight skin, and dense fleeces.
[21] Ringworm is a disease.
A.
Bacterial
B.
Protozoan
C.
Viral
D.
Fungal
Ans:
Fungal
Explanation :
Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term "ringworm" is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors. In pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs.

[6] Animals living in the three trunks are known as -
A.
Arboreal
B.
Voiant
C.
Amphibious
D.
Aquaticx
Ans:
Arboreal
Explanation :
Arboreal means living in trees. In every habitat in which trees are present, animals have evolved to move in them. Some animals may only scale trees occasionally, while others are exclusively arboreal. These habitats pose numerous mechanical challenges to animals moving through them, leading to a variety of anatomical, behavioral and ecological consequences. Arboreal species have behaviors specialized for moving in their habitats, most prominently in terms of posture and gait.

C.
Viral
D.
Fungal
Ans:
Fungal
Explanation :
Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term "ringworm" is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors. In pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs.
[22] Pituitary gland is situated in -
A.
the base of the heart
B.

A.
Clostridium
B.
Virus
C.
Bacteriophage
D.
Salmonella
Ans:
Clostridium
Explanation :
Tetanus s a medical condition characterized by a prolonged contraction of skeletal muscle fibers. The primary symptoms are caused by tetanospasmin, a neurotoxin produced by the Gram-positive, rod- shaped, obligate anaerobic bacterium Clostridium tetani which is a rod-shaped, anaerobic bacterium of the genus species Clostridium. C. tetani is found as spores in soil or in the gastrointestinal tract of animals. C. tetani produces a potent biological toxin, tetanospasmin, and is the causative agent of tetanus, a disease characterized by painful muscular spasms that can lead to respiratory failure and, in up to 40% of cases, death.
Explanation :
Oxygen is one of several dissolved gases important to aquatic systems. Dissolved oxygen is necessary to maintain aerobic conditions in surface waters and is considered a primary indicator when assessing the suitability of surface waters to support aquatic life. For maintenance of aquatic health, dissolved oxygen concentrations should approach saturation - that concentration which is in equilibrium with the partial pressure of atmospheric oxygen.
[10] An example of false fruit is -
A.
Apple
B.
Guava
C.
Mango
D.
Tomato
Ans:
Apple
Explanation :
An accessory fruit (sometimes called false fruit, spurious fruit, pseudofruit, or pseudocarp) is a fruit in which some of the flesh is derived not from the ovary but from some adjacent tissue exterior to the carpel. Examples of accessory tissue are the receptacle of strawberries, figs, or mulberries, and the calyx of Gaultheria procurribens or Syzygium jambos. Pomes, such as apples and pears, are also accessory fruits, with much of the fruit flesh derived from a hypanthium. Fruit with fleshy seeds, such as pomegranate or mamoncillo, are not considered to be accessory fruit.
[11] The green colour of the leaves is due to the presence of -
A.
Proteins
B.
Lipids
C.
Chlorophyll
D.
Carbohydrates
Ans:
Chlorophyll
Explanation :
The green color in leaves is caused by the presence of a compound called "chlorophyll," which the plant produces to do photosynthesis, which is how plants get energy from sunlight. The purpose of chlorophyll is to assist the plant in making food for itself by utilizing energy from sunlight and nutrients from the soil. The chlorophyll is green because it absorbs red and blue wavelengths of light — and so green is not absorbed and is reflected, making the plant look green to our eyes.
[12] The edible part of an onion is -
A.
Modified root
B.
Aerial flower
C.
Aerial stem
D.
Fleshy leaves
Ans:
Fleshy leaves
Explanation :
Edible plant stems are one part of plants that are eaten by humans. Most plants are made up of roots, stems, leaves, flowers, buds and produce fruits containing seeds. The edible portion in an onion is swollen leaves with a bit of stem. They are bulbs which, like garlic and leeks, are modified stems in which the primary storage tissue is expanded leaf bases. They come in white, yellow, and red varieties.
[13] Haemophilia is mostly associated with -
A.
Labourers
B.
Royal families
C.
Miners
D.
Sportsmen
Ans:
Royal families
Explanation :
Hemophilia is a group of hereditary genetic disorders that impair the body's ability to control blood clotting or coagulation, which is used to stop bleeding when a blood vessel is broken. It has been associated with royal families due to inbreeding, and is sometimes called the 'Royal Disease,' Queen Victoria of England had this disease. However, it can occur in any family as a result of genetic mutation or a change in the genetic code.

A.
Buffalo
B.
Cow
C.
Goat
D.
Donkey
Ans:
Goat

The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. Glucose levels are usually lowest in the morning, before the first meal of the day (termed the fasting level), and rise after meals for an hour or two by a few millmolar.
[19] The vector of disease sleeping sickness is -
A.
sand-fly
B.
house-fly
C.
fruit-fly
D.
tse-tse fly
Ans:
tse-tse fly
Explanation :
Sleeping sickness is caused by parasites transmitted by infected tsetse flies and is endemic in 36 sub- Saharan African countries. Without treatment, the disease is considered fatal. where there are tsetse flies that transmit the disease.
[20] The animal which can tolerate more summer heat is -
A.
Buffalo
B.
Cow
C.
Goat
D.
Donkey
Ans:
Goat
Explanation :
Some livestock (and people) tolerate heat better than others. Sheep and goats tend to be less susceptible to heat stress than swine, cattle, llamas, and alpacas. Hair sheep usually tolerate heat better than wooled sheep. This is why they are often used for training and trialing herding dogs. Fat-tailed sheep are also more heat tolerant. The European sheep breeds are usually the least heat-adaptive because they tend to have shorter bodies and legs, short, thick ears, tight skin, and dense fleeces.
[21] Ringworm is a disease.
A.
Bacterial
B.
Protozoan
C.
Viral
D.
Fungal
Ans:
Fungal
Explanation :
Dermatophytosis or ringworm is a clinical condition caused by fungal infection of the skin in humans, pets such as cats, and domesticated animals such as sheep and cattle. The term "ringworm" is a misnomer, since the condition is caused by fungi of several different species and not by parasitic worms. The fungi that cause parasitic infection (dermatophytes) feed on keratin, the material found in the outer layer of skin, hair, and nails. These fungi thrive on skin that is warm and moist, but may also survive directly on the outsides of hair shafts or in their interiors. In pets, the fungus responsible for the disease survives in skin and on the outer surface of hairs.
[22] Pituitary gland is situated in -
A.
the base of the heart
B.
the base of the brain
C.
the neck
D.
the abdomen
Ans:
the base of the brain
Explanation :
Pituitary gland or hypophysis, is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is not a part of the brain. It is a protrusion off the bottom of the hypothalamus at the base of the brain, and rests in a small, bony cavity (sena turcica) covered by a dural fold (diaphragma sellae). The pituitary is functionally connected to the hypothalamus by the median eminence via a small tube called the infundibular stern (Pituitary stalk).
[23] The percentage of Plasma in the total blood volume in human beings is about :
A.
45
B.
50
C.
55
D.
60
Ans:
55
Explanation :
Blood plasma is a yellowish colored liquid component of blood that normally holds the blood cells in whole blood. It makes up about 55% of the body's total blood volume.
[24] Both erythrocytes and leucocytes are formed in the .
A.
Bone marrow
B.
Thymus
C.
Arterial walls
D.
Lymph nodes
Ans:
Bone marrow
Explanation :
Leukocytes are immune cells that protect your body from infection, and they are found throughout your body, including your blood. Just like erythrocytes, leukocytes are made in the bone marrow.
[25] Tetanus is caused by -
A.
Clostridium
B.
Virus
C.
Bacteriophage
D.
Salmonella
Ans:
Clostridium
Explanation :
Tetanus s a medical condition characterized by a prolonged contraction of skeletal muscle fibers. The primary symptoms are caused by tetanospasmin, a neurotoxin produced by the Gram-positive, rod- shaped, obligate anaerobic bacterium Clostridium tetani which is a rod-shaped, anaerobic bacterium of the genus species Clostridium. C. tetani is found as spores in soil or in the gastrointestinal tract of animals. C. tetani produces a potent biological toxin, tetanospasmin, and is the causative agent of tetanus, a disease characterized by painful muscular spasms that can lead to respiratory failure and, in up to 40% of cases, death.
Explanation :
The normal core body temperature of a healthy, resting adult human being is stated to be at 98.6 degrees Fahrenheit or 37.0 degrees Celsius. Though the body temperature measured on an individual can vary, a healthy human body can maintain a fairly consistent body temperature that is around the mark of 37 degrees Celsius. The normal range of human body temperature varies due to an individual's metabolism rate, the higher (faster) it is the higher the normal body temperature or the slower the metabolic rate the lower the normal body temperature.
[18] Normal fasting blood sugar level per 100 ml. of blood in man is -
A.
30 - 50 mg
B.
50 - 70 mg
C.
80 -100 mg
D.
120 -140 mg
