Alita wants to know if the color of ice cream affects its taste. She has three batches of vanilla ice cream. Batch 1 has no food coloring, Batch 2 has red food coloring, and Batch 3 has green food coloring, She asks 10 people to taste the three batches of ice cream and choose their favorite. What is the independent variable in Alita's investigation? A. color of the ice cream

B. taste of the ice cream

C. number of batches of ice cream
D. number of people tasting the ice cream

A: The color

Explanation: Because thats whats she is trying to find out ФωФ

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.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
