3. refer to the figure showing a pedigree of a family affected by an x-linked recessive disorder. a female in generation 3 isn't a carrier of the disorder. how can this be?
o a females don't have x chromosomes so aren't affected by gene disorders passed on the x chromosome
bromatos receive an x chromosome from each parent, but in cases of cosive disorders, the mutated chromosome isn't passed on to daughters
fomalos receive x chromosomes from the fathers only, which are unaltected in this caso
d. pomalo receive an x chromosome from each parent if a mother is a correr of an x-linked rocessive disorder, her daughters have a 50 percent chance of receiving her normal
x chromosome and a 50 percent chance of receiving formulated x chromosome

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.

wait any answer choices plz

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
