This information can be useful to agriculture because bees are major pollinators of crops, so it is important to know which pesticides to manage in order to avoid risk to bee survival. That is option B.
Bees are one of the social insects that lives in societies that are based on a caste system.
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. 
Therefore,  it is important to know which pesticides to manage in order to avoid risk to bee survival.

Answer:
Hello your question is incomplete attached below is the complete question
answer : = 1.25
Explanation:
i) Determine the rate of mtDNA percent divergence 
From the data given the most closely related specie is Chimpanzee ( 8.8 sequence  difference ) 
Note : Given that this divergence took place seven million years from now 
∴The rate of mtDNA percent  divergence per 1 millions years 
 = 8.8 / 7 = 1.25

The correct answer is b.
The child is reaching for a toy which is not visible to him (hidden under a cloth), therefore, the child has a mental representation of the object in his/her mind. This action means that the child acknowledges that the objects continue to exist even when he/she can not hear or see them. This thought process is called object permanence and it is an ability acquired between the 4th and 7th month of a child's development.
