Answer: Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere's mixture of gases.
Explanation:
In addition to oxygen, the gases that make up the largest percentage of Earth's atmosphere may significantly include nitrogen, argon, carbon dioxide, etc.
Why oxygen is essentially required for living organisms?Oxygen is essentially required for living organisms because it helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their noses and mouth into their lungs.
Oxygen gives our cells the capability in order to break down food in order to get the energy they need to survive. Oxygen consists of 21% of the total earth's atmosphere along with 78% of the nitrogen and 1% of all rest of the gases like argon, carbon dioxide, etc.

Which compound that provides energy in cells is made in every tube where cellular respiration is occuring?
Answer:
ATP
Explanation:
Adenosine triphosphate, commonly known as ATP, is the chemical molecule that stores and provides/releases energy in cells. ATP is needed by the cells of every living organism and is obtained via a process called CELLULAR RESPIRATION.
Cellular respiration is the process whereby cells breakdown food molecules (sugar) to synthesize energy storing molecules called ATP. Hence, in every tube where cellular respiration is occuring, ATP is the produced molecule that provides energy.

B and b represent, respectively, the dominant and recessive alleles of a gene pair. Half of the F1 generation expresses the recessive condition, and the other half expresses the dominant condition. What are the most likely genotypes of the P generation
Answer:
Bb and bb
Explanation:
The most likely genotypes of the parental generation would be Bb and bb.
If Bb and bb are crossed, such that:
Bb x bb
offspring: Bb Bb bb bb
Bb = 2/4 = 1/2 = 50%
bb = 2/4 = 1/2 = 50%
hence;
1/2 or 50%% of the offspring would express the dominant condition in the form of Bb and the remaining 1/2 or 50% of the offspring will express the recessive condition in the form of bb.

Pharyngolaryngectomy involves surgical excision of the hypopharynx and larynx, reported with codes 31390 or 31395, and these codes are differentiated based on with or without ______________.
Answer:
The answer is "Complications"
Explanation:
Pharyngolaryngectomy is an operation to eliminate/remove the larynx (voice box) and the pharynx (the territory at the rear of the mouth and throat). The activity is intense, requiring a general anesthetic and a stay of a little while in medical clinic. Now and then it should be completed in two phases, the subsequent stage being to revamp the structures in your neck however much as could reasonably be expected. This will expect unions to be taken from your chest, back or lower arm.
You should be offered broad pre-operative guiding in anticipation of the deficiency of your voice, in spite of the fact that it is conceivable to recapture a decent measure of vocalization with language instruction. After the activity you should inhale through an opening in your neck which will be a permanent feature.

why saturated solution prepared at higher temperature gives crystal on cooling
Answer:
Cristal is formed when the solution is cooling because the solvent can't keep all the molecules of the substance and these molecules are beginning to leave the solvent and form solid crystals.
Explanation:
It means that every crystal is formed of one molecule of the solvent. When the solvent reaches room temperature, it is moved to the ice bath to finish the process of crystallization.
Protein molecules are the building blocks of the body. They are made up of long chains of amino acids. Draw the general structure of an amino acid.
Answer:
Please find the diagram of the general structure of amino acids attached.
Explanation:
Proteins are one of the four major biomolecules in living systems. As rightly stated in this question, they are building blocks of the body. However, proteins are biological polymers made up of monomeric units called AMINO ACIDS. A long chain of these amino acids make up a protein molecule.
An amino acid generally consists of a central carbon atom called ALPHA CARBON, attached to an amine group (-NH2), a carboxylic acid group (-COOH), and a side chain (R side chain). All 20 amino acids that exists in nature have this general structure but differs only in the type of SIDE CHAIN (R group) they possess i.e. all amino acids have a different R side chain.
Please find the diagrammatic representation of the general structure of amino acids as an attachment.

1. Do you think nuclear power is safe to use? Would
you feel comfortable living next to a nuclear power
plant?
Answer: No, I do not think that nuclear power is safe to use. Any radioactivity in general is dangerous in itself. I would not feel comfortable living near a nuclear power plant, due to the radioactivity, the pollution, and the huge health risks of doing so, such as extremely elevated risk for cancer
Answer:
I don't really think nuclear power is safe to use, it's too unpredictable. I would not want to live anywhere near a nuclear power plant on account of the fact that there have been multiple accidents involving nuclear power plants, for example, Chernobyl in 1986, Fu kushima in 2011, and Three Mile Island in 1979.

Maria walks up hill to go to school every day. When she reaches the top of the hill, she is always breathing much faster than when she started. How might this affect how her heart is working? Support your hypothesis with evidence.
Answer:
''By doing hard activity, the pumps very fast.''
Explanation:
''By doing hard activity, the heart pumps very fast.'' is my hypothesis. In this hypothesis, I mentioned that during hard activity pumping of heart goes very fast because our body needs oxygen as well as energy in the form of ATP and the only way to get both oxygen and energy is the pumping of heart which supply oxygen to the cell as a result energy is generated in the form of ATP and removes carbondioxide gas by breathing.

write any two method for identification of fossils?
Traces of the dead bodies present on the sedimentary rocks are fossils identification parts. By the physical appearance as well we can see the fossils and the types.
What are the ways by which fossils form ?Molds and the casts are the ways by through the fossils are formed out.
Something becomes fossil then it is mineralized or later becomes is made of the minerals. This is usually meaning an increase in the weight. A fossil bone is just heavier than the normal bone that is noticeably so. So if object is heavy then it just might be the fossil. Sediment might fill mould and later form cast fossil.
Have an eye that looks for the detail Look for the regular lines along with the marks or the patterns on the pebbles just like ridges or the growth lines in the shell. Looking for the tiny pieces that are among the beach pebbles and not only the big stones. Often the crinoid stems or the belemnites can also be small as the little fingernail.
