The Monarch butterfly mates in the spring just before it migrates north. The male transfers a capsule filled with sperm and food. The female butterfly flies north then lays her eggs on milkweed plants. The leaves of the milkweed plant nourish her newly hatched larvae. Which reproductive strategy does the monarch butterfly exhibit?
Sexual Reproduction
Asexual Reproduction
Both Types of Reproduction
The whiptail lizard is an all-female species and is able to reproduce without a male to fertilize her eggs through a process called parthenogenesis. After a false mating , the female will lay eggs. The daughters are genetically identical to their mom. What type of reproduction?
Sexual
Asexual
Both sexual and asexual
The sea horse is unique among fish: it mates for life with the same partner. It is the dad who gets pregnant. The female deposits her eggs in the male's pouch which are then fertilized.( The pouch is an external structure that grows on the body of the male) What type of reproduction?
Asexual reproduction
Sexual reproduction
Both Sexual and Asexual reproduction
The garden strawberry plant grows modified stems, called runners. Along the runners, tiny new strawberry plants take root. Each new plant is identical to the parent. Insect pollinators also visit strawberry flowers. Pollen from one flower join the eggs of another to form seeds that cover the strawberry fruit. What type of reproduction?
Sexual Reproduction
Asexual Reproduction
Both asexual and sexual reproduction
The common earthworm has both male and female reproductive parts. To reproduce, two worms come together to exchange sperm. each worm deposits its own eggs and the donated sperm into a gooey cocoon that if leaves in the soil. Baby worms emerge a few weeks later. What type of reproduction?
