Answer:
The correct answer is A) differentiated cells retain all the genes of the zygote
Explanation:
A plant can be cloned from the somatic cells which shows that the differentiated cell of plants have the ability to divide and differentiate to produce a new plant. This property of the cell is called totipotency.
All the cells in plants are not totipotent but some cells under proper condition can show the property of totipotency. Totipotency property shows that the differentiated cell is having all the genes that were present in the zygote.
This property of plant cells is used by scientist in plant tissue culture to produce plants for research and other purposes. So the right answer is A.

In order to improve the graph and make it more detailed in order to get a better perception why the honey bee populations are decreasing, there's few things that can be added.
- Number of bee keepers over the period
The number of the honey bee colonies is directly connected as to how many bee keepers there are. If there's a trend of a decline in the bee keepers, than there will be a trend in the decline of the honey bees.
- Area of trees suitable for the honey bees
The trees are crucial for the honey bees to be able to produce honey, thus it is very important that they have a certain area of trees on which they can feed upon. If there's a decline in the number of trees for the bees, than the bees will be dying from starvation.
- Pollution
The honey bees are animals that are very sensitive to changes in the environment, especially when it comes to pollution. If the levels of pollution are increasing in areas where there's honey bees, it will certainly affect their numbers in a negative manner.
