<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

Answer:
The shrimp population in a bay
Explanation:
Biotic factors are the living component of an ecosystem. These include the plants and animals that inhabit the area. The rest of the choices are the abiotic factors which describe the non-living component of an ecosystem. Abiotic and biotic factors are interrelated and together help to form an ecosystem and biome.
Answer:
1. Cells are composed of chemicals and both the structure and function of cells are regulated by the basic principles of chemistry. true
2. Scientists have successfully sequenced the entire genome of humans but have not yet sequenced the entire genome of any other species. false
3. Living systems are the most complex chemical systems on earth. true
4. Living systems are governed by the same principles of chemistry and physics that govern non-living systems. true
5. Living organisms contain unique chemical elements which are not found in non-living systems. false
6. An input of energy is required to maintain the complexity of living systems. true
7. The energy conversions that take place in living systems are governed by the same laws of thermodynamics that govern non-living systems. true
Explanation:
Cells are the basic unit of life which differentiate a living thing from a non- living thing. Although a living system, is made of the same chemical elements from which a non-living t=might be made, yet they are different from the non-living things as living things carry out the seven basic principles of live.
All living things carry genetic material from which their genome is made. Scientists have currently been able to sequence the genome of humans as well as many other organisms.
