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
Answer:
Computer automation is used mostly by industry in factories. However, it is also useful in science. Machines can be used to run automated tests and complete simple tasks. One example of a machine used in science is the robotic arm that is used to handle radioactive samples.
Explanation:
Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.
Staphylococcus is a Gram-Positive Bacteria i.e. it takes up the Gram stain.
Escherichia coli or E. coli is a Gram-Negative Bacteria i.e. it does not take up the Gram stain.
Gram Staining is done by immersing the bacterial sample in a solution of dye and then observing it under microscope after proper rinsing.
Gram Positive Bacteria are those bacteria that show a positive outcome on staining. Gram Positive Bacteria appear Stained after staining.
Gram Negative Bacteria are those bacteria that show a negative outcome on staining. Gram Negative Bacteria does not take up the stain and appear stainless.
The epidermis of Staphylococcus which is a Gram-Positive Bacteria appears to take up the stain whereas Escherichia coli which is a Gram-Negative Bacteria does not take up the stain.
Staphylococcus epidermis appears stained, whereas Escherichia coli appears stainless after the gram stain.
