[1] The large amount of sugar present in human blood is -
A.
sucrose
B.
glucose
C.
fructose
D.
lactose
Ans:
glucose
Explanation :
The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily a compact energy store. The mean normal blood glucose level in humans is about 4 mM (4 mmole, or 72 mg/dL, i.e. milligrams/ deciliter); however, this level fluctuates throughout the day.

A.
Greater than 20cm
B.
Lesser than 25cm
C.
Greater than 25cm
D.
Lesser than 30cm
Ans:
Greater than 25cm
Explanation :
For a hyper-metropic eye ,the near points shift away from the eye i.e. farther away from the normal near point (25cm).

The fresh leaves are an ingredient in many South Asian foods (such as chutneys and salads), in Chinese dishes, in Mexican cooking, particularly in salsa and guacamole and as a garnish, and in salads in Russia and other CIS countries. Chopped coriander leaves are a garnish on Indian dishes such as dal. The dry fruits are known as coriander or coriander seeds. In India they are called dhania. The word “coriander” in food preparation may refer solely to these seeds (as a spice), rather than to the plant. The seeds have a lemony citrus flavour when crushed, due to terpenes linalool and pinene.
[17] Which plant is called 'Herbal Indian Doctor'?

[20] If the radius of blood vessels of a person decreases his/her blood pressure will -
A.
increase
B.
decrease
C.
remain unaffected
D.
increase for males and decrease for females
Ans:
increase
Explanation :
An obese person has a greatly increased number of blood vessels because of the amount of adipose tissue that must be serviced. As a result, the total length of his or her vascular tree is greatly increased and this person tends to have a higher blood pressure because of the greater resistance to blood flow. Resistance is inversely proportional to the fourth power of the radius of the blood vessel. In other words, the smaller the diameter of the vessel, the greater the resistance it offers to blood flow.

roots & leaves
B.
leaves & flowers
C.
leaves & dried fruits
D.
flowers & dried fruits
Ans:
leaves & dried fruits
Explanation :
Coriander (Coriandrum sativum), also known as cilantro, Chinese parsley or dhania, is an annual herb in the family Apiaceae. All parts of the plant are edible, but the fresh leaves and the dried seeds are the parts most traditionally used in cooking. The fresh leaves are an ingredient in many South Asian foods (such as chutneys and salads), in Chinese dishes, in Mexican cooking, particularly in salsa and guacamole and as a garnish, and in salads in Russia and other CIS countries. Chopped coriander leaves are a garnish on Indian dishes such as dal. The dry fruits are known as coriander or coriander seeds. In India they are called dhania. The word “coriander” in food preparation may refer solely to these seeds (as a spice), rather than to the plant. The seeds have a lemony citrus flavour when crushed, due to terpenes linalool and pinene.
[17] Which plant is called 'Herbal Indian Doctor'?
A.
Amla
B.
Mango
C.
Neem
D.
Tulsi
Ans:
Amla
Explanation :
The Indian gooseberry, or aamla from Sanskrit amalika, is a deciduous tree of the family Phyllanthaceae. It is known for its edible fruit of the same name. Although these fruits are reputed to contain high amounts of ascorbic acid (vitamin C), 445 mg/100g, the specific contents are disputed, and the overall antioxidant strength of amla may derive instead from its high density of ellagitannins such as emblicanin A (37%), emblicanin B (33%), punigluconin (12%) and pedunculagin (14%). It also contains punicafolin and phyllanemblinin A, B, C, D, E and F. There is preliminary evidence in vitro that its extracts induce apoptosis and modify gene expression in osteoclasts involved in rheumatoid arthritis and osteoporosis. It may prove to have potential activity against some cancers.

[20] If the radius of blood vessels of a person decreases his/her blood pressure will -
A.
increase
B.
decrease
C.
remain unaffected
D.
increase for males and decrease for females
Ans:
increase
Explanation :
An obese person has a greatly increased number of blood vessels because of the amount of adipose tissue that must be serviced. As a result, the total length of his or her vascular tree is greatly increased and this person tends to have a higher blood pressure because of the greater resistance to blood flow. Resistance is inversely proportional to the fourth power of the radius of the blood vessel. In other words, the smaller the diameter of the vessel, the greater the resistance it offers to blood flow.
[21] Bee Keeping is known as -
A.

[16] In coriander, the useful parts are -
A.
roots & leaves
B.
leaves & flowers
C.
leaves & dried fruits
D.
flowers & dried fruits
Ans:
leaves & dried fruits
Explanation :
Coriander (Coriandrum sativum), also known as cilantro, Chinese parsley or dhania, is an annual herb in the family Apiaceae. All parts of the plant are edible, but the fresh leaves and the dried seeds are the parts most traditionally used in cooking. The fresh leaves are an ingredient in many South Asian foods (such as chutneys and salads), in Chinese dishes, in Mexican cooking, particularly in salsa and guacamole and as a garnish, and in salads in Russia and other CIS countries. Chopped coriander leaves are a garnish on Indian dishes such as dal. The dry fruits are known as coriander or coriander seeds. In India they are called dhania. The word “coriander” in food preparation may refer solely to these seeds (as a spice), rather than to the plant. The seeds have a lemony citrus flavour when crushed, due to terpenes linalool and pinene.
[17] Which plant is called 'Herbal Indian Doctor'?
A.
Amla
B.
Mango
C.
Neem
D.
Tulsi
Ans:
Amla
Explanation :
The Indian gooseberry, or aamla from Sanskrit amalika, is a deciduous tree of the family Phyllanthaceae. It is known for its edible fruit of the same name. Although these fruits are reputed to contain high amounts of ascorbic acid (vitamin C), 445 mg/100g, the specific contents are disputed, and the overall antioxidant strength of amla may derive instead from its high density of ellagitannins such as emblicanin A (37%), emblicanin B (33%), punigluconin (12%) and pedunculagin (14%). It also contains punicafolin and phyllanemblinin A, B, C, D, E and F. There is preliminary evidence in vitro that its extracts induce apoptosis and modify gene expression in osteoclasts involved in rheumatoid arthritis and osteoporosis. It may prove to have potential activity against some cancers.
[18] Which one of the following is a modified stem?
A.
Carrot
B.
Sweet potato

[20] If the radius of blood vessels of a person decreases his/her blood pressure will -
A.
increase
B.
decrease
C.
remain unaffected
D.
increase for males and decrease for females
Ans:
increase
Explanation :
An obese person has a greatly increased number of blood vessels because of the amount of adipose tissue that must be serviced. As a result, the total length of his or her vascular tree is greatly increased and this person tends to have a higher blood pressure because of the greater resistance to blood flow. Resistance is inversely proportional to the fourth power of the radius of the blood vessel. In other words, the smaller the diameter of the vessel, the greater the resistance it offers to blood flow.
[21] Bee Keeping is known as -
A.
Sericulture
B.
Apiculture
C.
Aquaculture
D.
Agriculture
Ans:
Apiculture
Explanation :
Beekeeping (or apiculture, from Latin apis, bee) is the maintenance of honey bee colonies, commonly in hives, by humans. A beekeeper (or apiarist) keeps bees in order to collect honey and other products of the hive (including beeswax, propolis, pollen, and royal jelly), to pollinate crops, or to produce bees for sale to other beekeepers. A location where bees are kept is called an apiary or "bee yard".

It is mostly water (93% by volume), and contains dissolved proteins, glucose, clotting factors, electrolytes, hormones and carbon dioxide (plasma being the main medium for excretory product transportation).
[13] "Sodium Pump" operates in -
A.
Muscle contraction
B.
Heart beat
C.
Nerve impulse
D.
None of the above
Ans:
Nerve impulse
Explanation :
Na+/K+-ATPase (also known as sodium-potassium pump) is an enzyme located in the plasma membrane of virtually every human cell and is common to all cellular life.

An obese person has a greatly increased number of blood vessels because of the amount of adipose tissue that must be serviced. As a result, the total length of his or her vascular tree is greatly increased and this person tends to have a higher blood pressure because of the greater resistance to blood flow. Resistance is inversely proportional to the fourth power of the radius of the blood vessel. In other words, the smaller the diameter of the vessel, the greater the resistance it offers to blood flow.
