Describe the amount of freshwater on earth and where it is used and stored
Sergeeva-Olga [200]

According to the U.S. Geological Survey, most of that three percent is inaccessible. Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps. The use for the water in the world is for household drinking water. The ocean stores about 97 percent of the Earth's water; the remaining three percent is stored in glaciers and ice, below the ground, in rivers and lakes. Of the world's total water supply of about 332 million cubic miles of water, about 97 percent is stored in the ocean.

Hope this helps!

finlep [7]

Answer:

GG, Gg, Gg, gg

Homozygous green – GG

Heterozygous green – Gg

Homozygous yellow - gg

Explanation:

It is given that allele for green seed pods (G) is dominant to the allele for yellow seed pods (g) which means that if “G” and “g” occur together, a trait associated with G will be expressed.  

The genotype of the true breeding Green plant is “GG”  

The genotype of the true-breeding yellow plant is “gg”  

F1 generation cross  

GG * gg

Offspring produced from F1 generation are – Gg, Gg, Gg, Gg

In f2 generation offspring of F1 generation are crossed among each other.  

So the offspring produced in F2 generation are  

Gg * Gg

GG, Gg, Gg, gg

Homozygous green – GG

Heterozygous green – Gg

Homozygous yellow - gg
