Answer:
MODES OF REPRODUCTION IN
BUTTERFLY
Butterflies land on the ground or a suitable perch to mate. After turning to face away from each other, they join the tips of their abdomens. The male then transfers a packet of sperm called a spermatophore to the female's body, where it will fertilize the waiting ova.
CAT
Feline reproduction is quite a unique process. Female cats are capable of induced ovulation. The female does not ovulate until the backward pointing spines on the male's penis stimulate the vagina. The male grabs her by the loose skin at the back of her neck (the scruff) and they mate briefly. Cats do not ovulate or release eggs into the fallopian tubes and into the horns of the uterus so that they can be fertilised until they have mated.
DOG
Dogs reproduce sexually, that means that a male and female dog must be involved. The male dog has sperm while the female dog has eggs. When it is time to reproduce, the male dog gets very closer to the female dog and puts his sperm inside her body. The sperm fertilize the eggs. Once the sperm is fertilized, they begin growing inside the female dog's body.
FROG
Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them. In this case, the eggs are fertilized inside the female's body before they are released.
MOSQUITO
After she obtains a blood meal, the female mosquito lays the eggs directly on or near water, soil and at the base of some plants in places that may fill with water. The eggs can survive dry conditions for a few months. The eggs hatch in water and a mosquito larva or "wriggler" emerges.
