You may talk about this picture:
A: it is an
ionic bond (which is a strong interaction, between two close atoms which has a large difference in their charges, like azote and oxygen)
B: is a
hydrogen bond (between O in a side and H in the other side)
C: it could be a
Van der Waals bond (small interaction between Carbon and hydrogen from different sides (London interaction))
D:
Hydrogen bond (between the Oxygen and hydrogen from different sides)
E: it's an
ionic bond
Answer:
the diagram shows the body structures that are similar though in different species due to common ancestry, this evidence is comparative anatomy.
Using the Punnet square, you find it is a 100% chance
Answer:
Genotype of parents: Ss x ss
Genotype of offsprings: Ss ss
Expected ratio of short to long: 2 : 2 = 1 : 1
The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3
Explanation:
In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).
A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.
For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have
Phenotype of parent: A short haired male and long haired female
Genotype of parents: Ss x ss
Genotype of offsprings: Ss ss
Expected ratio of short to long: 2 : 2 = 1 : 1
The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3
