Option A, 1/64
Explanation:
The genotype of a carrier female would be Pp
The genotype of a carrier male would be Pp
When these two adults are crossed , the following offspring are produced
Pp x Pp
PP, Pp, Pp, pp
Thus out of four children 3 children have normal phenotype but two are carrier.
So probability of having one normal child (with genotype PP) is 
So the probability of three normal children is

Hence, option A is correct
2 and 3 are too similar to distinguish because they both are saying it's been back up on several different accounts but 3 seems like a more solid answer go with 3
Answer:Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules.

triglycerides- fat
phospholipids- plant and animal cell membrane
sterols- plant and animal cell membrane's microorganism.
