Answer:
geographical isolation
Explanation:
Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.
There are two mechanisms of reproductive isolation:
- Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation, geographical isolation and behavioral isolation.
- Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.
<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>

During anaerobic respiration , cells make energy without <u>Oxygen</u>
the energy obtained during anaerobic respiration is 2 ATP
Answer:
The correct answer will be option-E
Explanation:
Hershey and Chase's experiment was performed to test whether DNA serves as the genetic material or protein.
To perform experiment they grew bacteriophage into radiolabeled phosphorus and sulfur compounds. The phosphorus is an integral part of the structure of DNA whereas proteins contain sulfur in their structure.
In the given condition if radiolabeled nitrogen is utilized then the experiment will fail as the structure of proteins also contains an amino group( NH₂) in their structure as well as DNA. The scientist will not be able to identify whether the DNA is the genetic material or protein.
Thus, option-E is the correct answer.
Green decade theory helps explain why coverage of ecology issues after the first earth day in 1970 sparked an increase in public concern about the environment.
The concept of green growth is concentrated to assume with economic growth and development can continue while combined with the negative impacts on the environment which include climate change are getting reduced while the natural environment continues to provide services concerned with ecosystem means to decouple.
The critical theory tradition contains the Green theory which makes sense that environmental issues arising out of questions about concerns among ourselves and others in the perspective of community and collective type of decision-making.
Green Growth results in the fostering of economic growth and development conditions while ensuring that the natural assets continue to provide the aspects of productive resources and environmental services where our well-being was settled up.
