THE TWO MOST COMMON REASON FOR MODIFYING THE LAND IN SOUTH AND SOUTH ASIA IS
(i) first is significantly, the area of lands categorized as under forest/woodland and wetlands declined .At the same time, cultivated area increased .
(ii) another is requirement of additional land due to increase in population.
Explanation:
Between 1880 and 1980, the South and Southeast Asian landscape underwent dramatic modification.The 81% of the lost forest and wetland vegetation appears to have been converted into expanded agricultural land.
Human population in this region more than tripled between 1880 and 1980, producing an enormous demand for additional land for cultivation.
The question is one of a dihybrid cross.
The picture that I attach below is a punnett cross of the parents (Yy Tt and Yy Tt).
So first you have to separate the two parents into gametes by pairing the alleles ( Yt , YT, yT, yt). Then I crossed then with the punnett square and from that we see that there are
two possible off spring that will would possess the genotype Yy TT (shaded gray in the diagram).
Thus the probability that a Yy TT offspring would be 2 out of 16

= 12.5 %
Wave interference may occur when two waves that are traveling in opposite directions meet. The two waves pass through each other, and this affects their amplitude. Amplitude is the maximum distance the particles of the medium move from their resting positions when a wave passes through.
Explanation:
Radioactive dating works on the principle that a radioactive isotope can decay into the stable daughter nuclei at a constant rate. Geologist generally use the principle for half life. Half life is the time required for half of the radioactive substance to decay. This is constant for a particular element.
