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

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
