A biologist uncovered a new species of multicellular organisms with chitin-based exoskeletons. Considering their structural characteristics, which kingdom would you classify these organisms into?*1 pointProtistsFungiPlantaeAnimalia

Each of these organisms are Arthropods because they have

In terms of the functionality of the endoskeleton, to which group are echinoderms most similar?Multiple choice question.NematodesChordatesArthropods

While researching a topic, a student has taken the following notes:The arthropod phylum encompasses cockroaches, crabs, butterflies, centipedes, scorpions, lobsters, and termites, among other creatures.The distinguishing characteristics of arthropods are a jointed skeletal covering (an exoskeleton) and a segmented body.Recently, scientist Sara Losso at Harvard University found an impeccably preserved arthropod fossil.The fossil was of a curled up arthropod, demonstrating an important arthropod survival tactic.In the Peleozoic Era, ancient arthropods curled up like armadillos to avoid danger on the seafloor.The student wants to emphasize the fossil’s significance. Which choice most effectively uses relevant information from the notes to accomplish this goal?The fossil Sara Losso found is an example of an arthropod, a creature with an exoskeleton and a segmented body. eliminateSara Losso of Harvard University recently found an impeccably preserved arthropod fossil. eliminateSara Losso’s well-preserved arthropod fossil illustrates a survival method of ancient arthropods, wherein they curled up.eliminateCockroaches, crabs, butterflies, and other arthropods have ancestors as old as the Peleozoic Era.
