Which is the outermost
planet in the solar system? Neptune
Severe deficiency of
Vitamin D results in __________. Rickets
The SI unit of charge is
__________? Coulomb
Long-sight defect could
be corrected by using __________ lens? Convex
Deficiency of Vitamin-A
results in __________? Night blindness
For a fixed mass of gass
at constant temperature, if we decrease volume, the pressure will _________? Increase
The lifespan of Red
Blood Cells is __________ days? 120
The density of water is
__________? 1 g/cm3
Radioactivity was
discovered by __________? Bacquerel
A device which converts
chemical energy into electrical energy is called __________? Battery
Batteries are devices that convert stored chemical energy into useful electrical
energy. It consists of a number of voltaic cells connected in
series by a conductive electrolyte containing anions and cations. A battery may be thought of as a clever variant of a standard
exothermic chemical reactor that yields chemical products with lower energy
content than the chemical reactants.
The Sun is a __________? Star
The gas used in a
refrigerator to cool water is___________? Tetrafluoroethene Tetrafluoroethene: It is one of the commonly
used refrigerant gases which you can find in almost all the present time
refrigerators. This gas is condensed effectively so that it can cool down the
surroundings of the machine without causing the problem of ozone depletion.
The average adult has a
blood volume of about __________ liters.
5
The most abundant
element in the universe is __________. Hydrogen
Hydrogen is the most abundant element in the
Universe; helium is second. However, after this, the rank of abundance does not
continue to correspond to the atomic number; oxygen has abundance rank 3, but
atomic number 8.
Each day human body
breathe in __________ liters of air. 10,000 to 15,000
The average adult at rest
inhales and exhales something like 7 or 8 liters (about one-fourth of a cubic
foot) of air per minute. That totals something like 11,000 liters of air (388
cubic feet) in a day.
The air that is inhaled is about 20-percent oxygen, and the air
that is exhaled is about 15-percent oxygen, so about 5-percent of the volume of
air is consumed in each breath and converted to carbon dioxide. Therefore, a
human being uses about 550 liters of pure oxygen (19 cubic feet) per day.
Deficiency of Vitamin-D
results in __________? Rickets
The SI unit of
“pressure” is _________. Pascal
The most densest
substance on the Earth is __________. Osmium
A camera uses a
__________ to form an image. convex lens
Which from the following
is NOT a conductor? Aluminium, Gold, Graphite All are conductors
CNG stands for? Compressed Natural Gas
Which from the following
is true for “Sound”? Sound cannot travel through a vacuum
When white light is
passed through a prism, it splits into __________ colours. 7
Dispersion
by a Prism: If a prism is placed in a room and a narrow beam of
white light is allowed to fall on one of its refracting faces, it is found that
light coming out from the other face of the prism is split in to seven colors
i.e violet,
indigo, blue, green, yellow, orange and red. This phenomenon is called dispersion at light. The
phenomenon of splitting of white light into its seven constituent colors is
called dispersion of light.
1 manometer = ? 10-9 meter
Instrument used for
measuring very high temperature is __________? Pyrometer
Sound waves are
_________ waves. Longitudinal
Sound waves
in air (and any fluid medium) are longitudinal waves because particles of the
medium through which the sound is transported vibrate parallel to the direction
that the sound wave moves. A vibrating string can create longitudinal waves as
depicted in the animation below.
The lifespan of White
Blood Cells is __________ day(s)? 5 – 21 days
White blood cells are made inside the bone marrow and stored in your blood
and lymphatic tissues. Because some white blood cells have a short lifespan of
one to three days, your bone marrow is constantly making them.
WBC have short life span of 5 – 21 days. The
lymphocytes are developed in the lymph glands. after which time they are
destroyed in the lymphatic system.White blood cells act as antibodies and
provide strength to body’s immune system. WBC are also
known as leucocytes.
Difference Between RBC
and WBC
Red
blood cells (RBC)
1. They do not have nucleus at maturity
2. They possess haemoglobin and are red
3. They help in transport of respiratory gases.
4. They are about 5 million/ mm3 of blood.
5. Life span 120 days
6. In the embryonic stage the RBC are formed in the live and
spleen. But after birth, they are formed in the red bone marrow. The process of
formation of RBC is known as erythropoiesis.
White
blood cells (WBC)
1. They have a large characteristic nucleus
2. They are colourless as they have no pigment
3. They help in defence mechanism
4. They are about 7000/mm3 of blood
5. WBC have short life span of 5-21
days
6. WBC are formed in the red bone marrow. The process of
formation of WBC is known as leucopoiesis.
The fluid part of blood
is known as __________? Plasma
During winter in cold
countries, the __________ is mixed to melt the ice on the icy roads. Salt
