What are the advantage and disadvantage of asexual reproduction?
Bacterial reproduction coli, reproduce asexually . An advantage of this is that they can produce many bacteria very quickly. A disadvantage is that all of the bacteria are genetically identical. If an antibiotic was used on the bacteria, then all of them would die.
What if all animals reproduce asexually how it will affect the ecosystem?
Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment.
Do worms reproduce asexually?
Most people already know that worms are hermaphrodites. This means that they have both male and female reproductive organs. However, they cannot reproduce alone. Worms can’t reproduce just any time.
How can you tell a male from a female worm?
Earthworms are hermaphrodites; that is, they have both male and female sexual organs. The sexual organs are located in segments 9 to 15. Earthworms have one or two pairs of testes contained within sacs. The two or four pairs of seminal vesicles produce, store and release the sperm via the male pores.
Are worms male or female?

What is the longest worm?
bootlace worm
What is the rarest worm?
Giant Palouse earthworm
Can a bootlace worm kill a human?
When agitated, bootlace worms produce a thick mucus that’s laden with a potent neurotoxin. Researchers studying the toxin say it can paralyze and kill cockroaches and crustaceans, though it likely is not harmful to humans.
What is the smallest worm?
Nematodes
Can nematodes kill humans?
There are many species of parasitic nematodes, and different species infect different hosts: some infect humans, some infect other animals and some infect plants. Chronic infection with intestinal nematodes can cause anemia, loss of appetite, gastrointestinal distress and, in some cases, even death.
Are nematodes bad for humans?
The nematodes are not dangerous for humans, animals and the plant itself. Nematodes are also used in organic farming to destroy pests without resorting to aggressive poisons. The big advantage: other insects such as bees are not affected by the useful earthlings.
Can you see nematodes?
Being slender and transparent, they cannot often be seen by the naked eye. Other groups of worms may be confused with nematodes. With a few exceptions, if you can see an organism, with the naked eye, it is not a plant-parasitic nematode.
