the r group or side chain of the amino acid glutamic acid is hydrophilic. The R group of the amino acid valine is hydrophobic. w
boyakko [2]

Answer:

You would expect to find glutamic acid on the fringes of the three-dimensional protein structure while valine would be found mostly inside the protein structure.

This is because hydrophilic molecules are ‘water-loving’ because they carry a charge and can, therefore, interact ‘positively’ with water by forming hydrogen bonds with the polar water molecules. Hydrophobic molecules on the other hand are water-hating. They carry no charge hence have no way of ‘positively’ interacting with the polar water molecules.

Remember the structure of the cell membrane too? The negatively-charged phosphate ends of the phospholipid bi-layer sandwich the non-polar fatty acid chains because they don't ‘like’ interacting with water. This applies to the same principle.

In fruit flies, curved wings (w) are recessive to the dominant straight wings (W), and ebony body (b) is recessive to the domina
lara [203]

Answer:

The correct answer =

parents : WwBb x wwbb

offspring :

WwBb, Wwbb, wwBb, and wwbb

Explanation:

It is given that the straight wings (W) is dominant over curved wings (w) and the ebony body (b) is recessive to the dominant gray body (B) and there is a cross between curved wings and ebony body and straight wings and gray body is made. The phenotypic ratio is: 1:1:1:1 for the four different phenotypes straight gray, straight ebony, curved gray, curved ebony.

It is not given the genotype of parents, however, for the curved and ebony fly, it is clear that both alleles are recessive as recessive alleles only appear in absence of the dominant allele of the trait.

For another parent, the possible genotypes can be  WWBB or WwBb, however in the case of WWBB the phenotypic ratio would not be equal therefore,

crossing WwBb x wwbb

This can be represented in the form of a punnett square as below:

          wb   wb           wb           wb  

WB WwBb WwBb WwBb WwBb Straight wing, Gray body

Wb Wwbb Wwbb Wwbb Wwbb Straight wing, Ebony body

wB wwBb wwBb wwBb wwBb Curved wing, Gray body

wb wwbb wwbb wwbb wwbb Curved wing, Ebony Body

The phenotypic ratio is: 1:1:1:1 for the four different phenotypes
