How to bring male and female gametes together?
Male and female gametes are brought together during the fertilization process, which results in the formation of a new individual. Depending on the species, this can happen either internally or externally.
How do snails fertilize internal or external?
Snails can either fertilize internally or externally, depending on the species. Most terrestrial snails, such as garden snails, engage in internal fertilization, where the male transfers sperm to the female's reproductive tract during mating. In contrast, some aquatic snails may practice external fertilization, releasing eggs and sperm into the water simultaneously for fertilization to occur. This variation in fertilization methods is influenced by their respective environments and reproductive strategies.
What is the egg laying process called?
Oviparous animals are known to lay eggs. Some egg laying species are internally fertilized while some are externally fertilized.
Do horses reproduce internally or externally?

Does a pigeon have a penis?

How does a fish reproduce?
Many fish reproduce sexually. The male fish will insert a part of his body into the female fish in order to fertilize her eggs. In some cases, the male fish will spread semen on the eggs after they leave the body of the female.
Does a newt have internal or external fertilization?
Internal
What is the process where sex cells fuse?
The process where sex cells fuse is called fertilization. During fertilization, a sperm cell from a male merges with an egg cell from a female, resulting in the formation of a zygote. This zygote contains a complete set of chromosomes, half from each parent, and begins to divide and develop into an embryo. Fertilization can occur internally or externally, depending on the species.
How do embryos develop externally?
Embryos develop externally through a process called embryogenesis. This involves the growth and differentiation of cells into specialized tissues and organs. The embryo receives nutrients and support from the environment through structures like egg membranes or placenta, depending on the species.
Are gills on the outside of the body?
Gills can be located both externally and internally, depending on the species. In many aquatic animals, such as fish, gills are typically found on the sides of the head, covered by a bony plate called the operculum. However, some organisms, like certain amphibians and mollusks, may have external gills that are visible outside the body. These structures function to extract oxygen from water.
