I'd say that the mechanism which might keep Rana aurora and Rana boylii from mating is B. temporal isolation, since their breeding seasons do not occur at the same time.
It is not anatomical isolation, since they are both frogs. It is not geographic isolation, since they meet in California. It is not behavioral isolation since they both have breeding seasons.
Answer:
See the answer below
Explanation:
Green and round pea plant has the genotype GGRr. Another pea plant with yellow and wrinkled peas has the genotype ggrr. Both were crossed
GGRr x ggrr
Genotypes of the Offspring:
8 GgRr
8 Ggrr
Phenotypes of the offspring (assuming G is dominant over g and R is dominant over r):
8 green and round peas
8 green and wrinkled peas

Basaltic has the least tendency to form pyroclastic flows
Answer:
Option (1).
Explanation:
Enzymes is the biocatalyst that has the ability to increase the rate of a biochemical reaction of the living organism. Enzymes decrease the activation energy of the reaction.
The bacterial cell has the ability to thrive into the human body and may acts as pathogen. The enzymatic activity of the bacterial cell can be increased by increasing the temperature but the temperature should be in the optimum range of the enzyme.
Thus, the correct answer is option (1).
Answer:
Allopatric speciation occurs due to the geographical isolation between individuals of the same species. The geographical isolation can be due to canyon development, mountain formation, migration, etc.
The geographical isolation gives different environmental condition to the separated population of same species to live which allow these two population to evolve differently and evolve in different species.
So when two population becomes different species and not able to interbreed with each other when give opportunity then the allopatric speciation between the two populations becomes complete.
