We are Martín, Eugenia, Carlota, and Gabriel, and we are going to talk about worms and mollusks.
00:00:00
Worms. It is used to refer to the members of three different species. Flatworms, nematodes, and alleles.
00:00:11
Worms, however, have common characteristics. They have bilateral symmetry. They tend to lie in humid climates.
00:00:19
Flatworms are the simplest animals that have bilateral symmetry and tefalisation of the nervous system.
00:00:33
The two most well-known groups of flatworms are tapeworms and canarians.
00:00:47
Tapeworms are parasites that live in the intestines of many animals, including human beings.
00:01:01
They do not have mouths because they are so resistant to the animals' intestines.
00:01:10
They get diabetes, so they work.
00:01:17
They are hermaphrodite and have the capacity to self-fertilize.
00:01:21
Clannarium.
00:01:26
These flatworms inhabit scenic climates and can be found in seas, rivers, and lakes.
00:01:28
They work self-fertilizing.
00:01:35
Some of them are parasites, others living independently of any host.
00:01:38
They have the following characteristics.
00:02:04
The digestive system, for example, and analgesic.
00:02:07
These things, on the whole world, they are all benefits in fact, analgesic.
00:02:11
They can help the person relaxing.
00:02:17
They may lay eggs inside a cup with other pellets inside, therefore, they can...
00:02:20
or they are in the... they are in cycle of the...
00:02:29
Anelites are worms with segmented, cylindrical bodies.
00:02:34
Some anelites, such as liches, can live in aquatic environments, and others, such as earthworms, live in semi-terrestrial environments.
00:02:39
Anelites have the following characteristics.
00:02:50
They have digestive tools, such as the mouth and anus.
00:02:54
The majority of aquatic annelids feed on plankton and others, such as leeches, feed on blood of vertebrates.
00:03:02
The biggest aquatic annelids live in deers and others carry out tenuous respiration.
00:03:12
Mollusks are invertebrates that have soft bodies and bilateral symmetry.
00:03:20
The majority of them are aquatic, although there are sea exceptions such as snails and slugs.
00:03:38
Their bodies are made of an external layer or mantle that surrounds their internal organs.
00:03:45
Many bodies have parts that are made of protective layers made of minerals.
00:03:58
Some have a defining head which has a mouth and very well-developed sense organs.
00:04:05
They have a mucus which they use to clean their mouth.
00:04:14
Some mollusks do this to clean their mouth.
00:04:21
Mollusks have a complete digestive tube.
00:04:24
Many of them have an organ in their mouth called retula.
00:04:27
Aquatic mollusks use dill's breath.
00:04:31
Some mollusks have a tongue that works the same way as a mollusk.
00:04:35
Monomotors are a group that is divided into beavers and cinnabars.
00:04:42
Beavers are aquatic invertebrates that have two external cells, or beavers.
00:04:49
They don't have an umbrella in their beavers because they are in their beavers.
00:04:54
There were two deals. They wanted one of those in useful shape and they used it to fit in the tabletop. I think I might have invented it, but I can't determine if it was a safe sell.
00:05:01
Gastropods have a defended head that has a mouth and four tickles.
00:05:23
A ported gastropod is made with gills, and to restore one, use an organ that functions as a lanyard.
00:05:30
These have a head and upper circulatory system.
00:05:37
Teleports are automatic in very many ways.
00:05:43
They move in the same direction as the head.
00:05:46
Teleports have an independent head for all ports.
00:05:50
Telapots have a well-defended head with primate-permined eyes.
00:05:54
Next to it is a fruit which is dried in a set of tentacles with suction cups that help the animal to catch prey.
00:06:01
They release water in order to move.
00:06:13
Some theropods, such as sequins, release dark pigment squid ink.
