It would automatically be assumed that an earthworm does not have a exoskeleton because of the way they look and feel. They are very flexible and soft to the touch.
Root cells lack chloroplasts.Thats because they do not get light.
In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
Proprioception
Grasshoppers do not have a shell like some other insects; instead, they have an exoskeleton made of chitin. They lack a coiled shell or a shell with two parts, as their body is segmented and covered by this hard outer layer. The exoskeleton provides protection and support, but it does not function like a traditional shell.
In a country with zero population, you would expect to find abandoned infrastructure, such as empty buildings, roads, and public facilities, as there would be no residents to maintain or utilize them. The landscape might reclaim these areas, with nature gradually overtaking urban environments. Additionally, there would be a lack of economic activity, cultural events, and social structures, resulting in a silent, desolate environment devoid of human presence and interaction.

An earthworm and all insects are invertebrates because they lack an internal skeleton, especially because they don't have a backbone.Well to tell you an earthworm is an invertebrate.An earthworm is an invertebrate.
Root cells lack chloroplasts.Thats because they do not get light.
That it lacks an abdomen, antennae, compound eyes, exoskeleton, legs, and thorax is a reason why earthworms are not insects.Specifically, all insects have a body divided into a head, thorax and abdomen; compound eyes; an exterior skeleton; a pair of antennae; and three pairs of segmented legs. An earthworm is recognizable by its streamlined body which has muscles, segments and setae. It lacks antennae, jointed legs, and segmented body parts.
No, a cricket is not a vertebrate because it does not have a backbone and has an exoskeleton. Vertebrates have backbones. Invertebrates lack a backbone.
Lack of parental involvement would be parents that pay little attention to their children
No, crayfish are invertebrate animals, they do, however have an exoskeleton which makes up for the lack of a backbone.
No , cockroach lack back bone . It is insect not a vertebrate .
In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
arthropods and mostly molluscas have exoskileton made up of chitin and calcium carbonate respectively
An earthworm's lack of appendages helps reduce drag as it moves through the soil, making burrowing more efficient. The worm's cylindrical shape also allows it to move easily through tight spaces underground. Additionally, the lack of appendages minimizes the risk of getting stuck in narrow tunnels.
