b. The woman may have different gender babies.

c. The woman with less stretch marks has larger skin cells.

d. The woman without stretch marks has more cholesterol in her diet, which affects her cell membranes.

Each caste performs a special task or series of tasks that serves as an economic importance to the agricultural system.

Pests such as parasitic mites cause poor agricultural yield. By using pesticides, which are protective chemicals, farmers have greatly improved crop yield.

The bee workers while in search of pollen from crops can be harmed from the pesticides that is being used to control parasitic mites. This can lead to Colony collapse disorder of the caste system of bees.
