If cells from a carrot are removed and placed in a culture medium, they can develop into a normal adult plant. this demonstrates that carrot cells

Carrot cells are 'totipotent'.

Explanation:

Totipotency is the genetic potential of a plant cell which have all the genes or genetic information by which the cell can be developed into the whole plant similar to the original plant.

Cells obtained from a carrot from its stem, root or any other parts and the cells are kept in a culture medium containing mineral nutrients, vi¬tamins and hormones. The cells in a medium allowed to divide.

As a result, the cells in culture will produce an undifferentiated mass of cells called callus. The callus can give rise to normal plant under given certain ma¬nipulations in the culture.

Thus, the cells of the callus are totipotent.  

27/12 or 2 3/12

Step-by-step explanation: First off we would need to find a common denominator, so all the fractions could be added together easily, and we could use a denominator of 12 because 6 times 2 equals 12, 4 times 3 equals 12, and 3 times 4 equals 12. So 5/6 would become 10/12, 3/4 would become 9/12, and 2/3 would become 8/12. So adding them all together would give you a sum of 27/12 or 2 3/12. Hope this helped!
