Answer:
Comparison of reproductive systems of frogs, dogs, and insects:
Frogs:
* 2 gonads (testes or ovaries), 2 oviducts, uterus, and external aperture (Cloaca)
* Gonads produce gametes, released into body cavities, mixed to form eggs
Dogs:
* 2 testis/ovaries, 2 fallopian tubes, uterus, vagina, 1 egg per cycle
* Gonads produce gametes, released into body cavity and mixed to form a single placenta
Insects:
* 2 testis/ovaries, 2 oviducts, uterus, external aperture (Spermatophore)
* Gonads produce gametes, mixed to form large number of eggs
Similarities between the reproductive systems of frogs, dogs, and insects:
* Gonads: Produce and store gametes
* Oviducts: Carry gametes from gonads to external opening
* Uterus: Supports development of embryo
* Egg: Large cell containing genetic material of mother
* Sperm: Small male gamete that fertilizes egg during copulation
