Answer;
The Water Cycle
The water cycle creates clouds, snow, sleet, rain and hail. Precipitation, perspiration, etc.
Explanation;
-Water changes from a liquid to a gas form, called water vapor, through a process called evaporation. As liquid is heated by the sun's warmth, it changes into a gas form and rises in the atmosphere. In the air, water vapor cools and returns to a liquid form. This process is called condensation.
These water droplets cling together and form clouds. When the droplets become heavy enough, they fall to the ground as precipitation.
The central tendon of the diaphragm
It's a combination of alleles that determines the number of phenotypes for a given trait.
Answer:
Ratio of red flowers: white flowers = 169: 131 = 9: 7 as given in the question. It is clear that the color is possible only by at least 2 genes.
Let assume genes are A and B.
Now the cross AaBb (Red) x AaBb (Red)
Gametes ----------> AB Ab aB ab AB Ab aB ab
AB Ab aB ab
AB <em>AABB (Red) AABb (Red) AaBB (Red) AaBb (Red)
</em>
Ab <em>AABb (Red) AAbb (White) AaBb (Red) Aabb (White)
</em>
aB <em>AaBB (Red) AaBb (Red) aaBB (White) aaBb (White)
</em>
ab <em>AaBb (Red) Aabb (White) aaBb (White) aabb (White)
</em>
The ratio of Red flowers: White flowers is 9:7
The red color flower is produced when both the alleles of genes are dominant. if any of the alleles of genes is recessive, it will produce the white color flower. This is one of example complementary gene interaction where the presence of both genes in the dominant form complements each other to produce red color flowers.
