Answer:Here are the appropriate terms to fill in the blanks:1. Oviducts: The internal reproductive system of female insects consists of a pair of lateral and median oviducts (through which the eggs pass to the outside).2. Spermatheca: A spermatheca (which stores sperm until they are needed for fertilization).3. Ovarioles: Each ovary consists of a cluster of ovarian tubes, known as ovarioles. The ovarioles contain a series of developing eggs, which will pass into the lateral oviduct upon maturation.4. Testes: The male reproductive system consists of a pair of testes, each containing a series of sperm tubes where spermatozoa are produced.5. Sperm ducts: Mature sperm pass through the sperm ducts and out of the insect through the ejaculatory duct.For frogs:6. Oviducts: The female reproductive system of a frog has a pair of ovaries, a pair of oviducts that open into the cloaca individually.These terms describe different parts of the reproductive systems of insects and frogs, essential for reproduction and fertilization processes.
