Phenotypes are the physical characteristics that result from the genotype, which is the genetic makeup of the organism. In this case, either straight hairline or Widow's peak will be the phenotype, as they are the physical characteristics being discussed.
The questions states that a Widow's peak is dominant over straight hairline. So we are going to assume that the Widow's peak allele is W (dominant), and the straight hairline allele is w (recessive).
A dominant allele will mask the presence of a recessive allele unless both of the alleles are both recessive (both ww).
So for the WW genotype, we are going to see the dominant phenotype: Widow's peak.
For the Ww genotype, we are also going to see the dominant phenotype since the dominant allele is going to mask the presence of the recessive allele, so we are going to see: Widow's peak.
Lastly, for the ww genotype, we are going to now see the recessive phenotype, since both alleles are recessive: straight hairline. Note that their are two of these type of offspring as stated in the question.
Bacteria divides and reproduce by the process of binary fission.
Because we control them both in the same direction so if we where like some lizards that move each eye individually then we would see two images
Enzymes are biological catalysts which increase the rate of biochemical reactions without undergoing any change themselves. They bind with the substrate to form a enzyme substrate complex leding to the formation of product releasing free enzyme.
Enzymes have an optimum pH at which they show their maximum activity. Any change in the pH effects the enzyme and the enzymatic reaction. Most of the enzymes are functional at the neutral pH of 7 in the cell cytoplasm with a few exceptions. An acidic environment in the cell, changes the tertiary structure of the enzymes and the bonds of the enzymes are weakened. Thus, preventing the substrate binding to the active site of the enzyme and inhibiting catalysis. This is due to the change in the structure of the active site leading to the lack of electrostatic attraction between the enzyme and the substrate.
