the correct answer is A- Reproductive isolation occurred through behavioral isolation
A process of formation of a new species from an existing species is called speciation. New species may formed due to geographical or reproductive barriers which isolates the members of a population of a species to form a new species.
In the given question, speciation in In the leopard frogs occurred due to a particular or specific call given by males to the females. The courtship call lead to reproductive isolation due to change in behavior. Such type of behavioral change will help in recognizing mates of the same species and this will act as a reproductive barrier among the other related species.
The endocrine system is made of glands that secrete hormones. These hormones help regulate the organs and cells activity. The hormones among other things control your metabolism.
Evolutionary theory predicted that bacterial resistance would happen. Given time, heredity and variation, any living organisms including the bacteria will evolve when a selective pressure, in this case an antibiotic is introduced. However it also gives doctors an patient some specific strategies for delaying even more widespread evolution of antibiotic resistance; these strategies include; avoid mild doses of antibiotics over long time periods, don't use antibiotics to treat viral infections, when treating bacterial infection with antibiotics, take all the pills, and also using combination of drugs to treat a bacterial infection.

Photosynthesis is using Light Energy to convert CO2 and water into oxygen and carbohydrates such as sugar or starch.
Cellular respiration is using oxygen to convert biochemical energy into ATP (Energy) and CO2
The relationship between the 2 is that what the 2 creates and let out is what the other needs to work like photosynthesis creates oxygen as a byproduct and to do cellular respiration, it needs oxygen. Cellular respiration creates CO2 as a byproduct and to do photosynthesis, it needs CO2.
