Answer:
33.3 cM
Explanation:
Parent 1: blue shell, long antenna : BBLL
Parent 2: green shell, short antenna : bbll
BBLL X bbll :
F1 : BbLl ( blue shell, long antenna )
BbLl X bbll :
BL/bl = 82 : Parental
bl/bl = 78 : Parental
Bl/bl = 37 : Recombinant
bL/bl = 43 : Recombinant
Total = 240
Recombination frequency = (Number of recombinants/ Total offspring)*100
= (80/240) * 100 = 33.33 %
Map distance = recombination frequency
Hence, map distance = 33.3 cM
Answer:
Continental drift
Explanation:
Alfred Wagener told about continental drift. He said that continents were a single land mass called Pangaea. They were separated and relocated in the form of different continents. The drifting happens due to the movement of tectonic plates above the magma. As a result, the land mass was broken down into different landforms. These broken parts were carried slowly and form the continents. The continents are now also moving slowly

Explanation:
The old growth forests are full of full of the trees that are rich in the valuable timber, while environmentalists seek to preserve the forests for its benefits.
These old grown trees are economically very important and it serves animals in providing habitat and food. There are huge variety plants and trees that can be used for the medical purposes too.
The large and old trees have strong and big wooden pieces that can be used in logging industry.
