Answer:
4N
Explanation:
Mitosis is the process whereby a cell duplicates or produces another identical copy of itself. The mitotic process, which occurs in four main stages produces two daughter cells that are genetically identical to the parent cell. For example, a diploid organism (2n) will produce two daughter cells with 2n from mitosis.
However, in a case whereby a plant cell (A) screws up mitosis during metaphase and pulls full copies of all chromosomes to one side. This would result in one daughter cell having 4n or tetraploid number of chromosomes. Ideally, mitosis separates the chromosomes equally into the two daughter cells to have 2n each. If one cell has all chromosomes, it means that cell will have all the 4n.
For example, in a diploid human cell with 46 chromosomes (2n). Mitosis should occur in such a way that each daughter cell will have a diploid 46 number of chromosome (2n). However, if all the chromosome ends up in one cell during mitosis, that cell will have 92chromosomes, which is 4n or tetraploidy.
Answer:
a.
Explanation:
ice is a solid, and solids flow slowly, unlike liquids. I know 100% that it is not D because water causes erosion as well.
Bromothymol blue is an indicator for weak acids and bases.It is used to observe photosynthetic acvtivities and for respiratory indication.
Blue Bromothymol indicator will turn to green then to yellow when CO2 is added.When O2 is added, no effect is noticed in the Blue Bromothymol because Oxygen doesnot affect the pH.
In a summary, the color indication follows;
- Yellow-to indicate acidic
- Green-for neutral solutions
- Blue-for alkaline solutions.
Answer:
Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
- sensory systems-detects ratios of glycolytic intermediates,
- global regulators-control the expression of genes that encode for enzymes.
