Based on your Punnett square for question number 5, what percentage of guinea pigs will have long hair and what percentage of guinea pigs will have short hair if parents have the genotypes BB and bb? (Remember: In guinea pigs, short hair is dominant to long hair.)

The correct answer would be :

Long hair guinea pig = 0%

Short hair guinea pig = 100%

Explanation:

It is given in the question that the Guinea pigs have a gene for the length of the hair have two alleles long hair and short hair where short hair is dominant and long hair is recessive.

short hair = B

long hair = b

Cross between BB and bb, there will be gametes B, B, and b, b.

    B     B

b  Bb   Bb

b  Bb   Bb

So there is all the offspring are in a heterozygous condition which means the dominant allele only expressed in offspring which is short hair so the percentage of the short hair guinea pig will be 100% and zero percentage for long hair.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
