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
