Answer:
Water has properties of cohesion and adhesion.
Explanation:
The single Hydrogen atom and double Oxygen atoms attach to each other in such a way their are minute polar polarity differences. Electron bonds will combine to form one side of the compound as being positive and the other side positive. Positive side of other H2O molecules will attach to the negative side. This bond causes water to adhere to sides of a glass test tube.
Will also create a bead when it drips on another non-porous surface. Adding soap will break the bead (surfactant). Water is the perfect solvent.
Well to begin with this process is called genetic engineering, the scientists altered the DNA of the chickens instead of altering a protein already in the chickens because when you alter the DNA the offsprings of the chicken will will have the same qualities while if you only alter the protein already in that chicken only that chicken will be able to do the job

Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
