Animals reproducesexually.They produce a haploidsperm cell(a male sex cell) and a haploidovum(a female sex cell) that unite at fertilization to form a diploidzygote. Conversely, some animals are capable of asexual reproduction. For instance, some cnidarians produce a genetic clone by budding. Ot...
Unlike many other snail species that reproduce asexually, assassin snails actually have separate male and female sexes. However, distinguishing between the sexes is impossible because of the lack of sexual dimorphism in the species. The males and females are the same size and shape. The breeding ...
These polyps reproduce asexually through producing columns of disks called ephyrae. These ephyrae then break out of the columns and grow into medusae, which are basically tiny jellyfish. These medusae grow until they too are ready to reproduce sexually. Though the rule of thumb is that the ...
Polyp. It then grows into a cylindrical colony of polyps. An adult Turritopsis dohrnii can return to this stage of development through cell transdifferentiation (see notes 1). Buddying Polyp. The polyp reproduces asexually by dividing in half repeatedly to produce genetically identical copies. Ephy...
Indeed, for many species such as the kobudai, the capacity to switch sex is highly adaptive. If an individual fish can reproduce as a female for the first portion of it’s life, then continue breeding as a male for the rest, it effectively doubles up on its reproductive output. Being ...
Fucking animals – or having them fuck you or otherwise stimulate you sexually – is not the same thing at all. If we were meant to do so, we would have body parts that match more closely, and we would be able to reproduce with them. Neither is the case. ...

(medicine) aid that cloning could provide.called them "as safe to eat as the food we eat every day. "And when those clones reproduce sexually(有性繁殖),the agency says, their offspring(后代) are safe to eat as well.The United States this year could become the first country to allow ...
The simplest of the animals is the sponge, which reproduces asexually, have unspecialized cells and no organ systems, as they get most of their nutrition from the flowing of water through the cellular layers. The chordates include mammals, birds, reptiles, and amphibians, among others. ...
Ephyra:after forming a new set of muscles and nerves, a section of a polyp (either the original polyp or clone) becomes an ephyra, an organism that can swim independently, grow and feed. Medusa:this is a fully-grown adult jellyfish, which can reproduce sexually with another jellyfish (...
