Answer:
The correct answer would be - 16 chromosomes or 8 chromosome pairs per cell.
Explanation:
In the body of an organism, all the somatic cells have the same number of chromosomes irrespective of their location in the body which is 2n or diploid. Liver cells would also have 2n number of chromosomes. The diploid number of cells are produced by the mitosis type of cell division or by fusing the sex cell that are egg cells and sperm cells. These sex cells are haploid of n number of cells or haploid.
If a sex cell as given in question sperm cells have 8 chromosomes then the liver cell would be 2n because sex cells after forming a zygote develooped to all other somatic cells including liver cells.
Sex cell = n = 8 chromosomes
liver cell - 2n = 2×8 = 16 chromosomes.
Answer:
The correct answer would be - option B. information system.
Explanation:
DNA is the unit of heredity as it contains the genetic code of an organism which is carried all the genetic information and transfer from the parent cell to the daughter cell. It also carries the information required for making all essential proteins in an organism.
So, if an organism did not have DNA, it would be missing the information system which is also responsible for the cell division other than given information.
Answer:
Four
Explanation:
During spermatogenesis, some diploid spermatogonia become larger in size and transform into primary spermatocytes. These diploid primary spermatocytes enter meiosis to produce haploid spermatids. One primary spermatocyte enters meiosis-I and produces two secondary spermatocytes. These secondary spermatocytes are haploids. Each of these two secondary spermatocytes enters the meiosis-II and produces two haploid spermatids. In this way, one diploid primary spermatocyte produces four haploid spermatids.
The elements that are characterized by the presence of an incomplete d sublevel are called "Transition Elements". The general properties of Transition Elements are; first, they are commonly high melting point metals, second, they have many oxidation states, third, they commonly form colored compounds, lastly, they are also paramagnetic.
