Answer:
a) Mitotic metaphase
8 picograms
b) a primary oocyte (metaphase)
8 pecograms
c) a secondary oocyte (metaphae)
4 pecograms
d) a first polar body (metaphase)
4 pecograms
Explanation:
a) In mitotic phase the chromosome numbers remains same as 8 because in this phase duplicated chromosomes align in center and separate to other poles. Therefore the amount of DNA will be 8 pecograms.
b) after the mitotic meta phase the cells divide into daughter cell with equal proportion of DNA which means each cell have 8 chromosomes. therefore they both contain 8 pecograms of DNA. The new daughter cells called as primary oocytes.
c) These primary oocytes (8 chromosomes) divides into two secondary oocyte each contain 4 chromosomes which means each cell have 4 pecograms of DNA.
d) Duplication of chromosomes occur in secondary oocyte and cell divides into polar body (4 chromosomes) and ovum (4 chromosomes). Therefore first polar body have 4 pecograms of DNA in it.

When Linnaeus created the taxonomic categories, the Kingdom was originally the largest one. However, in modern biology, Domain is sometimes written above Kingdom. So, the answer here is either of the two, depending on if you've discussed Domain in your class or not!

Answer:
The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body. THE DEGISTIVE TRACT begins at the mouth and ends at the anus. It is like a long muscular tube, up to 10 metres long, with digestive organs attached along the way.
