Of all the water on the earth, only about 3% is fresh water. 68% of all the freshwater is frozen as glaciers and is unavailable

AleksAgata [21]

Answer:

The correct answer is statement A.

Explanation:

The procedure of purifying ocean water, that is, the saline water so that it can become suitable for drinking is termed as desalination. Almost 70 percent of the Earth is covered with water and of this only 3 percent is used for drinking purposes. On a huge scale, the process of desalination would require the boiling of water, which would eventually require an enormous amount of energy.

Reverse osmosis and electro-dialysis are the methods used for desalination. However, these procedures are very costly and cannot be performed on a huge level as it can affect the economy of various countries.

How many chromosomes are found in the organism that results from the union of a human sperm cell and an egg cell?

Liono4ka [1.6K]

A human has a total of 46 chromosomes (23 from daddy and 23 from mommy). :)
A sperm cell has 23 chromosomes and an egg cell that has 23 chromosomes. 23 + 23 equals 46. Sometimes (due to mutations), a person
may have less chromosomes than they need. This may cause some problems like Turner syndrome(treatment can help aid the situation but, it can't be cured).
Hope this helps you :)

mRNA Molecule : A U G A A C C A U U C A G U A U G G

Translation:

Conversion of mRNA into proteins

Translate the mRNA into the corresponding amino acids.

mRNA Molecule : A U G A A C C A U U C A G U A U G G
