Bond [772]
<h2>Postzygotic isolation </h2>

Explanation:

In the given information of edible frog both male and female hybrids exist, but when they mate among themselves, they cannot successfully produce offspring which defines that postzygotic isolation exists between the two frog species

  • Postzygotic isolation prevents the formation of fertile offspring
  • Before the postzygotic isolation can happen, there must be an offspring born from a male and female of two different species
  • This means there were no prezygotic isolations, such as the fitting together of the sex organs or incompatibility of the gametes or differences in mating rituals or locations, that kept the species in reproductive isolation    
  • The offspring of two different species known as a hybrid is not always viable
  • Sometimes, they will self-abort before being born and other times, they will be sickly or weak as they develop

Once a standard curve has been prepared by plotting numbers of bacteria (CFU/mL) versus absorbance for one species of bacteria,
Vika [28.1K]

Answer:

b. False

Explanation:

The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.

A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.

  • The rate of bacterial cell reproduction varies from a particular species to another.
  • Varying species have different absorbance thresholds.
