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.

Answer:

The amount of water vapor in a given volume of air is humidity.The amount of water vapor in the air at any one time depends on temperature . Warmer air holds more water than cooler air. Clouds form when humidity is low and thetemperature is high . Relative humidity is defined as the amount of water vapor in the air divided by the amount that would have to be present in the same air to form a cloud or condense on a surface. Dew is related to the humidity of the previous day. The air temperature at which water vapor in the air condenses onto cool surfaces is the dew point.

 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.

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.

Answer:

Explanation:

I just took a test that had this question and this was the answer.

The statement which best  compares segmented worms and roundworms is that some segmented worms have setae, but roundworms do not.

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.

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.

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).

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

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.

Explanation:

Answer:

1) Tetanus is a potentially fatal bacterial infection that affects the nerves

2)Tetanus causes painful muscle contractions, particularly in the jaw and neck. It can interfere with the ability to breathe, eventually causing death.

3)  infants and the elderly are most likely but every one can get it.

4) The tetanus vaccine is made by taking the tetanus toxin and inactivating it with a chemical. The inactivated toxin is called a "toxoid." Once injected, the toxoid elicits an immune response against the toxin

5) Tetanus antiserum was developed in 1890, with its protective effects lasting a few weeks. The tetanus toxoid vaccine was developed in 1924, and came into common use for soldiers in World War II.

6)CDC recommends tetanus vaccination for all babies and children, preteens and teens, and adults

7) After the initial tetanus series, booster shots are recommended every 10 years.

8)help your immune system protect against these infections

9)Reported tetanus cases have declined more than 95%, and deaths from tetanus have declined more than 99% in the United States since 1947.

10) although the tetanus vaccine can be a very rare cause of a short-lived allergic reaction called "anaphylaxis," the tetanus vaccine does not cause death so the benefits outweigh.

11)They are most commonly found in animal manure and contaminated soil, but may exist virtually anywhere.

Tetanus is a bacteria

The symptoms are muscle spasms and paralysis and or stiffness in muscles

Everyone can get tetanus

Vaccines work by adding a little of the bacteria so your immune system can get a little of tetanus to know how to defend against it.

The first vaccine was produced in 1924

everyone should receive it

you should get one every 10 years

This is important because tetanus is not rare and can cause life changing effects like paralysis

no there has been no real big changes as far as i know

People who vaccinate have a small risk of contracting tetanus from the shot, and people who don't vaccinate could get really bad if not life threatening cases of tetanus.

Yes Defiantly

im not sure about this one

Hope this helps!
