If you meant "distributed" and not "disturbed" it is distributed through the water/ hydrologic cycle.
The reason why the RNA has decrease stability compared to
DNA is because the DNA, is lacking a hydroxyl group in which making it more
stable than of the RNA, that is why RNA has decrease stability than the DNA.
Answer:
The answer is DNA replication and crossing over.
Explanation:
Both meiosis and mitosis are reproduction processes taking place in humans. But there is some difference between these two processes. In meiosis, parent cell produces four daughter cells which are not identical to each other.
In meiosis, when DNA replicates it produces four haploid daughter cells in which the number of chromosomes in half. Moreover crossing over and separation of chromosomes also occurs to produce sperms and egg cells. While in mitosis crossing over and DNA replication is absent.
Diploid cells = 2n = 46
Haploid cells = n = 23
therefore, there are 23 chromosomes in haploid cells.
Answer:
Function of each male reproductive system-
They produce, maintain and transport sperm and semen . They discharge sperm into the female reproductive tract. They produce and secrete male sex hormones.
Function of each female reproductive system-
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur.
