Alli and her classmates want to know which species of oak produces the acorns that squirrels prefer. which possible procedure is likely to produce the most reliable results?
a. work together to observe where one squirrel spends most of its time, and record which acorns it buries for one hour, repeating daily for two weeks.
b. dig up and identify each type of acorn buried under one tree at the end of each day for a three-week period.
c. divide up and observe squirrels in ten locations for two hours, then dig up and identify each type of acorn buried by squirrels, repeating daily for two weeks.
d. observe and record the number of squirrels that approach each species of tree in a specific location for one hour each day for two days.

Option C, Divide up and observe squirrels in ten locations for two hours, then dig up and identify each type of acorn buried by squirrels, repeating daily for two weeks.

Explanation:

“Divide up in groups and observe squirrels in ten locations” This step will help Alli and her classmates to observe the squirrel at different locations. This will also help the group to note down the differences at ten different locations in terms of difference in species of squirrels, their fooding habit and preference towards a specific acorn plant.  

Repetition of this process for next two weeks will help the group in identifying the pattern of squirrels burring the acorn as if which type of acorn do they prefer for  burying.  

Hence Option C is the correct answer

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
