a.
Reflection.
b.
Refraction.
c.
Total internal reflection.
d.
Rectilinear propagation of light.
2.
Lactating mother,requires more protein and energy to compensate these nutrients secreted in the milk. If these nurtrients are not provided to her in the diet it will affect
a.
milk production.
b.
her own health.
c.
both of these.
d.
none of these. .
3.
When a bicycle tube is pumped up, the bicycle pump gets heated. Which of the following is the cause of production of this heat energy ?
a.
Transformation of mechanical energy spent in compressing the air particles against the pressure of air inside.
b.
Transformation of mechanical energy spent in overcoming friction.
c.
Both of these.
d.
None of these.
4.
High protein and carbohydrate diet is recommended during fevers, burns and after surgery because
a.
the7e is more catabolism.
b.
it helps in quick recovery.
c.
both of these.
d.
digestion is improved.
5.

a.
diet surveys of normal healthy people.
b.
chemical assay.
c.
ralcrobiological assay.
d.
methods involving laboratory animals.
6.
Why the hair of a painting brush stick together when taken out of water ?
a.
Because the free surface of water tends to contract.
b.
Because the cohesive force between the molecules of water more in air than in water.
c.
Because the water glues the hair together.
d.
Because the adhesive force between the molecules of water and the molecules of hair is very strong.
7.
A person who does heavy (manual) work as compared to counterpart who does sedentary (office) work needs
a.
equal amount of energy and protein.
b.
less energy, more protein.
c.
more energy.
d.
more protein.
8.
Why does the pressure of air in tyres increase when the vehicle is set in motion 'I
a.
The rotatory motion of the wheels of the vehicle contributes to this increase in pressure.
b.
When the vehicle is in motion, the molecules of the air in the tyres acquire more kinetic energy. This increase in kinetic energy is responsible for the increase in pressure.
c.
Because the tyres suffer a slight contraction when they are in motion.
d.
The temperature increases, air in the tyres expands. . Therefore, there is a slight increase in the pressure of air.
9.
Why steam causes more severe burns than boiling water ?
a.
Because steam contains a greater amount of heat.
b.
Because the temperature of steam is more than that ~off bboiling water.
c.
Both of these.
d.
None of these.
10.
To assess a nutritional status of a population, which of the following methods will be most appropriate ?
a.
Taking heights and weights and comparing these with normal heights and weights meant for that particular age.
b.
Any clinical symptoms.
c.
Anthropometric measurements.
d.
All of these.
