Mesorchium in frogs:
1. | is a double fold of peritoneum that adheres testes to kidney. |
2. | is a double fold of peritoneum that adheres ovaries to kidney. |
3. | is the outer cortical part of testes. |
4. | is the outer cortical part of ovaries. |
Statement I: | In male frogs, the testes are found adhered to the upper part of the kidneys and have a functional connection with the kidneys. |
Statement II: | In female frogs, the ovaries are situated near the kidneys and there is no functional connection with the kidneys. |
