Stem cells grown on a hard, rigid surface are biased into differentiating into a bone cell lineage. <span />
Answer:
WHO is involved: (major protein players)
WHAT is being completed:
WHEN does it occur in the cycle of the cell:
WHERE does it occur in prokaryotes or eukaryotes:
WHY does replication happen:
Explanation:
These are the 5 W's for any situation in life but directly applied to biology and DNA these are the exact and specific W's
Answer:
4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.
Explanation:
Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.
Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.
The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).
RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes
RRtt, Rrtt -> Red petals with short bushes
rrTt, rrTT -> pink petals and tall bushes
rrtt-> pink petals with short bushes.
These are the four phenotype variations possible in this dihybrid cross.

Answer:
B One allele from each parent
Explanation:
You have dominant genes (brown eyes) and recessive genes (green eyes)
In order for a child to be born with brown eyes only one parent needs to have brown eyes. Having green eyes is recessive so either both parents need to have green eyes or neither of them needs to have them. But if one parent has green eyes and the other has brown eyes, then the brown eyed gene will almost always dominate the green eyed one.
I hope this helps! :)
