Answer :
Final Answer:
The male frog is typically stimulated for sexual activity by injecting hormones. So, the correct option is d.
Explanation:
In laboratory settings, the stimulation of male frogs for sexual activity often involves the administration of hormones to induce mating behavior. This process, known as hormonal priming, involves injecting specific hormones, such as luteinizing hormone-releasing hormone (LHRH), to mimic the natural triggers for mating. These hormones act on the frog's reproductive system, stimulating the release of sex hormones, ultimately leading to increased mating behavior and receptiveness.
The administration of hormones is a precise process requiring careful consideration of hormone dosage and timing. Researchers calibrate the hormone dosage based on the species, age, and reproductive stage of the frogs involved. This calibration ensures that the injected hormones effectively stimulate the reproductive system without causing adverse effects. The timing of hormone administration is also crucial, aligning with the natural breeding cycle of the frogs to maximize effectiveness.
This method of hormonal stimulation provides a controlled approach to induce mating behavior in male frogs, facilitating research and breeding programs in laboratory settings. By mimicking natural hormonal cues, researchers can reliably stimulate sexual activity in frogs, aiding in studies related to reproduction, behavior, and conservation efforts for various frog species. Therefore, the correct option is d.
