Answer:
The bacterial cells transformed with PUC18 and plasmid lux grow in the presence of ampicillin, because the DNA of bacterial cells had incorporated parts of plasmid DNA and became ampicillin resistant.
Explanation:
The bacteria showing this property is mainly known as Escherichia coli (E. coli). These bacteria cells generally shows no growth in presence of antibiotic like ampicillin. Whereas when these cells are treated with PUC 18 and plasmid lux, then the bacterial DNA undergo certain transformation due to incorporation of strands of DNA of plasmid into them. This transformation make them resistance to ampicillin, when they are cultured in agar media with ampicillin in it.
The answer is albedo. This, in Latin, means whiteness meaning the measure of diffuse reflection of
light of a surface. Albedo scale is 0 – 1 with 0 representing no reflection (black
body) while 1 represents a total
reflection of incident light. Albedo is
used in astronomy and climatology.
Your correct answer would be "figure B" mainly because of the fact that a polygon would be a shape that would contain no curves what so ever. And as we can see above, figure b would contain this.
Your answer: Option B.
Answer:
1/2 or 50%
Explanation:
The question involves a single gene coding for coat color in cattle. According to the question, the allele for red coat (R) is codominant to the allele for white coat (W). This means that neither of the two alleles are dominant nor recessive over one another, hence, they are both phenotypically expressed in their hybrid offspring (Roan coat, WR).
In a cross between two roan cattle (WR), each cattle will produce gametes with W and R alleles. Using these gametes in a punnet square (see attached image), a total of four possible offsprings will be produced with genotypes: RR, WR, WR, and WW.
RR (1/4) : Red coat
WR (1/2 or 2/4) : Roan coat
WW (1/4) : White coat
Based on this, the probability of producing an offspring that will be roan from the cross between two roan cattles is 2/4 equivalent to 1/2.
