Question Discussion & Solution

It is not always necessary that we need a movie and an actor for a song. A song can be created without them. Microphone is also not essential for a song but lyrics are an essential part of a song as lyrics are the words that actually make up a song. Without, lyrics a song cannot be written.

House Q is diagonally opposite to Y and R is diagonally opposite to W, then the arrangement will be like:

So, definitely house E is facing T.

1^st letter: Decrease by - 1

O - 1→ N – 1 → M - 1 → L – 1 → K

2^nd letter: increase by + 2

L + 2 → N + 2→ P + 2 → R + 2 → T

3^rd letter: Decrease by - 1

T - 1→ S – 1 → R - 1 → Q – 1 → P

As the total distance between A and G is equal to E and D i.e. 20 km. So BD = 20 – (10 + 1) = 9 Km.

Hence, the distance between B and D is 9 km 

The Correct Answer is "boron deficiency".

• Boron deficiency is a deficiency of the micronutrient boron in plants.
• It causes large losses in crop production and crop quality
• It affects the vegetative and reproductive growth of plants, resulting in inhibition of cell expansion, death of meristem, and reduced fertility.

​Important Points

• Boron deficiency in sugar beets characteristically causes the death of the growing point and the development of blackheart rot.
• Before the deficiency has reached this stage, the leaves, which may have cracked petioles, will have become progressively smaller and somewhat misshapen.
• After the death of the growing point, small bunches of leaves develop in the older leaf axils and the crown is very liable to become hollow and rot.

Additional Information

• The hollow heart is an internal disorder where a 'lens' or 'star'-shaped cavity forms in the tuber.
• It appears to be caused by an abrupt change in tuber growth rate which usually occurs after a period of stress.
• Water, heat stress and associated calcium deficiency appear to have a role in the development of a hollow heart.
• The crisp variety Atlantic and the French fry variety Russet Burbank are prone to hollow heart but if conditions are right most varieties can be affected.
• Hollow heart is an important problem for the potato industry as payments from processors and washer-packers for fresh market potatoes may be reduced.
