  2. It is the color of danger

  3. Both A and B

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer

Very large particles may scatter light of which color?

  1. Blue

  2. Violet

  3. Indigo

  4. White
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fine particles scatter light of shorter wavelength and larger particles scatter light of longer wavelength. However, if the size of the scattering particles is large enough, then, the scattered light may even appear white.

What are the colours of the Sun observed most during sunrise/sunset and noon? 

  1. white and red

  2. reddish and orange

  3. yellow and reddish

  4. orange and blue
Reveal answer Fill a bubble to check yourself

Which wavelengths are the most effective in photoperiodism?

  1. Green and yellow

  2. Blue and red

  3. Blue and violet

  4. Red and far-red
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Photosynthesis requires light between 400 and 700 nm. Blue light promotes vegetative growth. Red and far-red promotes stem elongation. Red and blue light promotes flowering. Photoperiodism is best seen in red light as chlorophyll strongly absorbs red light and carries out photosynthesis. Hence, red light stimulates plant growth.

Thus, the correct answer is option D.

Select the correct pair

  1. Spring wood-light colour, high density

  2. Spring wood-dark colour, low density

  3. Autumn wood-light colour, high density

  4. Autumn wood-dark colour, high density
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A.False – Secondary xylem formed during spring season, during the secondary growth of dicotyledonous stem is called Spring wood or early wood. It is light coloured and high density.

B.False - Secondary xylem formed during spring season, during the secondary growth of dicotyledonous stem is called Spring wood or early wood. It is light coloured and high density.

C.False – Secondary xylem formed during autumn season, during secondary growth of dicotyledonous stem is called autumn wood or late wood. It is dark coloured and high density.

D.True - Secondary xylem formed during autumn season, during secondary growth of dicotyledonous stem is called autumn wood or late wood. It is dark coloured and high density.

So, the correct option is ‘Autumn wood- dark colour, high density’.

  1. Brown, Blue and Green.

  2. Blue, green and brown.

  3. Green, blue and brown.

  4. Green,brown and blue.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A 3 pin plug consists of three pins (hence the name). Each pin must be correctly connected to the three wires in the electrical cable. Each wire has its own specified color so as it can be easily identified.
The LIVE wire is RED OR BROWN. This is connected to a fuse on the live pin. The electric current uses the live wire as its route in.
The NEUTRAL wire is BLUE OR BLACK. This is the route the electric current takes when it exits an appliance; it is for this reason the neutral wire has a voltage close to zero.
The EARTH wire is GREEN OR  YELLOW and connected to the earth pin. This is used when the appliance has a metal casing to take any current away if the live wire comes in contact with the casing.

A ramus communicans consists of

  1. White ramus only

  2. Grey ramus only

  3. Both A and B

  4. Red ramus only
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ramus communicans is the branch which connects the spinal nerve and the sympathetic trunk.  There are two forms of ramus communicans. They are gray ramus communicans and white ramus communicans. They are responsible for conduction of signals in the sympathetic nervous system. The white rami communicans are the preganglionic sympathetic outflow from the spinal cord. The gray rami communicans contain postganglionic nerve fibers of the sympathetic nervous system and are composed of largely unmyelinated neurons.

So, the correct answer is option C.
