The statement which best compares segmented worms and roundworms is that some segmented worms have setae, but roundworms do not.
What are roundworms?Roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum.
Nematodes species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time. A 2013 survey of animal biodiversity published in the mega journal Zootaxa puts this figure at over 25,000. Estimates of the total number of extant species are subject to even greater variation.

Explain the correlation between chemical properties and chemical changes. (plz i not sure on the answer so it would mean a lot if you could help me.)
Answer:
Explanation:
A chemical property describes the ability of a substance to undergo a specific chemical change.
A chemical reaction is a process that occurs when one or more substances are changed into one or more new substances.
Differences
Chemical properties are properties that can be observed or measured when a substance undergoes a chemical change.
Physical properties are properties that can be observed without bringing a chemical change.
Another one
chemical properties; can be used to predict how substances react.
chemical changes; It is mostly used in identifying or describing the substance.
. Guillermo was finding it difficult to walk up the steps to his family’s apartment. His doctor thinks that his cells might not be getting enough oxygen or glucose. Which body systems should the doctor test in order to find out whether Guillermo’s cells are getting enough oxygen and glucose and why? (Sentence starter: The body systems Guillermo should have tested are .
Answer:
Because oxygen is the combustion fuel and glucose is the substrate needed for synthesis of energy as ATPs during cellular respiration.Therefore Guillermo lacks enough energy as ATPs in her body cells, especially skeletal muscles cells to complete the task of ascending the s steps.
For all the mitochondrial in cells(sites of energy production) to receive needed glucose,and other metabolites needed for energy synthesis; an efficient transport system is needed, so that these materials are available immediately, in required amount. This system is called circulatory system.
And for the the supply of combustion fuel (oxygen) needed for the completion of the ATP synthesis mechanisms; respiratory systems which convey oxygen from the external environments to the circulatory system through breathing mechanisms, for distribution is needed.
Thus the doctor needs to test both the circulatory and respiratory systems.
