Answer: ... being that the food she eats food that contains a lot of protein and also starch, so systems are both good for you and work together. Chemical energy is stored in the bonds of sugars. When a sugar molecule is broken down, a usable form of energy is released for the cell's life functions. Cells can release energy in two basic processes: cellular respiration and fermentation. ... In cells use oxygen to release energy stored in sugars such as glucose.
Explanation:
Answer:
What does she need from the food she ate and the air she breathes so that she can go on her run?
A. Rosa needs carbohydrates rich food (bread) to carry out her jogging activity. Protein-rich food before exercise is not recommended unless she is on a weight loss program (diet plan).
B. Rosa needs oxygen to perform aerobic respiration, which is required for maximum release of energy (36 molecules per reaction run). Anaerobic reactions yield less energy (2 molecules of ATP per reaction run) and are not recommended.
How do Rosa's body systems work together to get the molecules she needs into her cells?
Rosa's body cells need carbohydrates (glucose) and oxygen to perform aerobic respiration for the release of maximum energy. The glucose and oxygen molecules are provided to the cells via diffusion into the bloodstream. During exercise/jogging, complex molecules of carbohydrates such as starch (present in bread) are broken down into simple molecules (glucose) which are diffused into the blood. Likewise, a high amount of oxygen is provided to the body's cells via diffusion in blood, which is carried out by the faster movement of lungs and heart. The combined action results in the supply of both types of molecules to enter the cell where mitochondria use these substrates to produce energy molecules (ATPs).

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.

If two oceanic plates move towards each other at a convergent boundary, then_____ may occur.
earthquakes
faults
ocean formation
mountains
volcanoes
island chains
seafloor spreading
pick two events
Answer:
I think the answer is Volcanoes.
Explanation:
If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate. The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.

1. Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+, what is the formula for the compound?
2. Explain what electric forces between oppositely charged electrons and protons have to do with chemical reactions.
3. If the linear molecule beryllium dichloride (BeCl₂) has polar bonds because CI attracts electrons more strongly than Be, why is the molecule nonpolar?
Answer:
Artificial diamonds are made using thallium carbonate. If thallium has an oxidation number of 1+ number 2 A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds. number 3 giant metallic, giant ionic, simple molecular, and macromolecular ... it has positive ions surrounded by a sea of delocalised electrons ... m/z value than Cl⁻. this means that F⁻ is more attracted to the Ca²⁺ ion more strongly ... What bond angle does beryllium chloride, BeCl₂ have? ... Give two examples of linear molecules.
The formula of thallium carbonate is Tl₂CO₃. The intermolecular force of attraction between electrons and protons proceed to the combination of two atoms. The net dipole moment in BeCl₂ is zero since they cancel each other due to linear geometry.
What is thallium carbonate?Thallium carbonate is an inorganic compound formed by the ionic bonding between thallium and carbonate group. The charge of thallium Tl is +1 and that of carbonate group is -2. Hence the chemical formula of the compound is Tl₂CO₃.
Unstable atoms with deficient number of electrons combines with other atoms to form compounds. The force that act between the two atoms is called intermolecular force of attraction.
The electrons of an atom is attracted by the positive charge of nucleus of other atom results in the chemical bonding.
Barium chloride is an ionic compound with linear geometry. The chlorine atom is highly electronegative and will attract the shared pair of electrons into it.
The two chlorines are arranges linearly on either side of Be thus, the dipole will be opposite in direction towards each chlorine atoms. Thus it cancel and net dipole moment become zero. That's why the compound is nonpolar.

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.

. 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.

(Sentence starter: The molecules Rosa needs from the food she eats and air she breathes are...
Answer: What does she need from the food she ate and the air she breathes so that she can go on her run?
A. Rosa needs carbohydrates rich food (bread) to carry out her jogging activity. Protein-rich food before exercise is not recommended unless she is on a weight loss program (diet plan).
B. Rosa needs oxygen to perform aerobic respiration, which is required for maximum release of energy (36 molecules per reaction run). Anaerobic reactions yield less energy (2 molecules of ATP per reaction run) and are not recommended.
How do Rosa's body systems work together to get the molecules she needs into her cells?
Rosa's body cells need carbohydrates (glucose) and oxygen to perform aerobic respiration for the release of maximum energy. The glucose and oxygen molecules are provided to the cells via diffusion into the bloodstream. During exercise/jogging, complex molecules of carbohydrates such as starch (present in bread) are broken down into simple molecules (glucose) which are diffused into the blood. Likewise, a high amount of oxygen is provided to the body's cells via diffusion in blood, which is carried out by the faster movement of lungs and heart. The combined action results in the supply of both types of molecules to enter the cell where mitochondria use these substrates to produce energy molecules (ATPs).
How do hair cells use these molecules to release energy for her body to run?
The substrates (glucose and oxygen) enters the bloodstream and then taken up to the cell. Then they are provided to the mitochondria for the release of energy in the form of ATP. This is why mitochondria are known as the powerhouse of the cells. Within the cell, energy is released in a three-step process, i.e. glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. In the end, aerobic respiration per reaction run produces 36 molecules of ATP which are sufficient to meet intensive energy needs. During excrcise, the supply of oxygen and glucose is also faster due to faster lungs and heart actions.
PS: Anaerobic respiration cannot meet energy demands faster because the reaction produces only 2 ATP molecules per reaction run.
Explanation:
The molecules Rosa needs from the food she eats and air she breathes are
Food which are rich in carbohydrate to help her jog. This is because she is on a weight loss program which needs her to avoid proteinFurthermore, she would need oxygen so that she can successfully have aerobic respiration where there would be maximum release of energy to enable her complete her run better
According to the given question, we can see that Rosa wants to lose weight and she takes peanut butter which she takes and she is breathing normally which helps her perform aerobic respiration.
As a result of this, we can see that there is a need for Rosa to have the right diet which would help her with her jogging and weight loss program.
This would need foods that are rich in carbohydrate which would enable her to lose weight better and oxygen so that she could be efficient with her jogging and burn fat.
