Which statement best compares segmented worms and roundworms?
Some segmented worms have setae, but roundworms do not.
Some roundworms have setae, but segmented worms do not.
Segmented worms have sense organs, but roundworms do not.
Roundworms have sense organs, but segmented worms do not.
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.

Is a change in matter that produces one or more substances
Chemical change
Physical change
Chemical reaction
Answer:
Chemical change
Explanation:
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.
its not physical change: What is a physical change? A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
its not chemical reaction: A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products

. 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.

C) donate protons to solution
D) conduct electricity in water
Answer:
Hello There!
Explanation: Your Answer will be, D) conduct electricity in water.
Both acids and bases conducts electricity and water.
When acid dissolves in water, they are good electrolytes.
When bases dissolves in water they are good electrolytes.
Electrolytes are liquid or molten substances that are able to conduct electricity.
they conduct electricity by the use of their ions in solution.
Since acid and bases ionize in solution, they will conduct electricity.
An acid is a substance that produces excess hydroxonium ion in solution.
A base produces excess hydroxyl ions in solution. Hope This Helps!

Explanation: V2O5 + CaS → CaO + V2S5. 5V2O5 + 5CaS → 10CaO + 5V2S5. 3V2O5 + 3CaS → 3CaO + 3V2S5.
Why does Mercury have almost no atmosphere?
Mercury spins on its axis too fast to have an atmosphere.
Radiation from the Sun blows the atmospheric particles off into space.
Mercury's gravity is too weak to hold an atmosphere.
Mercury orbits the Sun at such high speed that the atmosphere is blown away.
Answer:
There are two main reasons. First, Mercury is small and doesn't have much gravity so it's hard to hold onto an atmosphere. Second, Mercury is close to the Sun so any atmosphere gets blasted away by stuff being blown off the Sun.
Explanation:
Because Mercury has no atmosphere, it can't hold onto its heat very well. The night side of Mercury gets very cold, which brings down the average temperature of the planet and makes it only the second hottest planet in the Solar System after Venus.
