The right options are; amphibians  and lancelets

Vertebrates are all species of animals that belongs to the subphylum; Vertebrata. Vertebrates are chordates that have a spinal cord enclosed by cartilage or bone. Vertebrates include mammals, reptiles, birds, fish, and amphibians. The vertebrate skeleton is made up of a brain case, bones, vertebrae, and gill arches (in fish and some amphibians).

First, let's define vertebrate. 
Technically speaking, a vertebrate is in the sub-phylum Vertebrata (Phylum Chordata). It must have a notochord and/or spine.

Now we know what a vertebrate it, we can answer our question.

Are starfish vertebrates? No.
Are earthworms vertebrates? No.
Are tunicates vertebrates? No.
Are crabs vertebrates? No.
Are amphibians vertebrates? Yes.
Are lancelets vertebrates? Yes.
Are octopus vertebrates? No.
Are grasshoppers vertebrates? No.

Why? Grasshoppers and crabs have exoskeletons (No bones). Octopus and starfish have no spinal column/backbone. Does it look like Tunicates or earthworms have spines?

At a deep sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which of the following?
Zielflug [23.3K]

Answer:

I would say part of an ecosystem and community.

Explanation:

An ecosystem is a biological community of interacting organisms and their physical environment .In the bottom of the sea,there are already many animals living here and when the whale fall appears at the bottom of the ocean it becomes apart of the ecosystem as it provides them with food.

This is because when a whale dies, its body often falls to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale  fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed  on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath  the whale body, and bacteria feed on the whale bones.
