Earthworms

Earthworms in the class oligochaeta, which is in the phylum annelida. Ecdysis occurs in the phylum arthropoda. My guess is that earthworms' cuticles undergo a process closer to our skin's than ecdysis.

no

The conversion between international units (IU) and grams (gm) depends on the substance being measured, as different substances have different conversion factors. For example, 1 IU of vitamin D is approximately 0.025 micrograms (mcg), while 1 IU of insulin is around 0.0347 mg. To convert 1,000,000 IU to grams for a specific substance, you would need to know the specific conversion factor for that substance.

Earthworms believe it or not have an anus (a bottom) where waste goes through their body and comes out the other end. You learn about the earth worm in biology class.

If your talking about the trash "waste" earthworms eat the soil and things in the soil and faeces it out. The faeces is very good for the plant and it is called soil. Also the earthworms eat away the "waste" creating holes near the roots of the plant which is important because the plants need carbon dioxide to live.

Earthworms are living things.

The gizzard in an earthworm is a muscular, thick-walled organ that grinds up food, particularly organic matter and soil particles. This mechanical digestion process helps break down food into smaller pieces, making it easier for digestive enzymes to further process the material in the following intestine. The gizzard plays a crucial role in the earthworm's ability to extract nutrients from its diet, contributing to its overall health and function in the ecosystem.

No, but they have cartilage. That's what makes the Earthworm move!

In the episode: "The last one"

most of the time white stuff seperates out. What used to be a homogenous mixture no longer can be considered a solution. Often times heavier liquids will settle to the bottom. I think the soap is still good if you can get it to mix again.

The earthworm is related to the clam-worm, the leech, polychate worms, and oligochaete worms.

its mouth

Vegetarians don't eat any animal.

no the earthworm is an invertebrate and therefore has no backbone.

yes and no it does have a brain it is tiny because an earthworm is tiny compared to us humans.

because there dj earworms

Earthworms are an invasive species in North America. They were brought in 10,000 years ago by glaciation and some brought in by Europeans during colonization.

The earthworm is a segmented worm with a true coelom which is partitioned into separate segments. There are many internal structures that are repeated within each segment. Each segment is surrounded by both longitudinal and circular muscles allowing earthworms coordinated movement. The fluid filled coelom acts as a hydrostatic skeleton. Each body segment contains four pairs of chaetae, bristles that provide traction for movement. Also the first four segments make up the anterior head region of the external structure of earthworms. The first segment is the periostomium which bears the mouth and the anus is found in the last posterior segment.

New cells grow on their ends causing work to get longer

Yes. Yes they do.

monkey ,snake,cow,mouse ,dog

not all of them.

The earthworm like many more complex organisms has a closed circulatory system, meaning that its blood is confined to blood vessels and its blood is recirculated so it gets maximum use
