One percent of a human's DNA is used for coding Information for the synthesis of proteins.
What is DNA?
DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

Why is air considered a solution?
Answer:Air is a solution made up of many gases. ... There is more nitrogen than any other gas in air, so it is considered the solvent in an air solution.
Explanation:
2C4 H10 + 13O2 -→ 8CO2 + 10H2O If 356 moles of O2 are available to react, how many moles of CO2 will fom?
Answer:
Answer:
The mole ratio of C₄H₁₀ and CO₂ is 2 : 8, which simplifies to 1 : 4.
Explanation:
The mole ratio is the relative proportion of the moles of products or reactants that participate in the reaction according to the chemical equation.
The chemical equation given is:
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
Once you check that the equation is balanced, you can set the mole ratios for all the reactants and products. The coefficients used in front of each reactant and product, in the balanced chemical equation, tells the mole ratios.
In this case, they are: 2 mol C₄H₁₀ : 13 mol O₂ : 8 mol CO₂ : 10 mol H₂O
Since you are asked about the mole ratio of C₄H₁₀ and CO₂ it is:
2 mol C₄H₁₀ : 8 mol CO₂ , which dividing by 2, simplifies to
1 mol C₄H₁₀ : 4 mol CO₂, or
1 : 2.

Which formula represents a
polar molecule
containing polar covalent bonds?
A. H2O
B. CO2
C. NaCL
D. Cl2
Answer:
A. H2O
Explanation:
Let us first define the three types of bonds:
1. Nonpolar Covalent: electronegativity difference < 0.4
2. Polar Covalent: electronegativity difference between 0.4 and 1.8
3. Ionic: electronegativity difference > 1.8
This will help us eliminate choices C and D:
-NaCl has a electronegativity difference of 3.0 - 0.9 = 2.1 (ionic bond)
-Cl2 has a electronegativity difference of 3.0 - 3.0 = 0 (nonpolar covalent bond)
However, we still have two more options, A and B, but they are not diatomic for us to use the electronegativity differences with.
We must now consult their geometries. Because CO2 has a linear geometry (O=C=O), the two sides will cancel each other out, resulting in a nonpolar covalent bond. At this point, by process of elimination, we can already determine the answer to be A. H2O. We can verify this by looking at the geometry of H2O, which is bent (H-O-H; imagine the O is above the H's, I cannot draw it in this response). H2O's bent geometry classifies it as polar covalent; the electrons are slightly more attracted towards the O, the more electronegative element. Side note: this makes the O slightly more negative in charge, whilst the H's are slightly more positive in charge.
P.S. I apologize for not being able to draw and demonstrate that last paragraph, but I hope you get a general idea. You can search up the "H2O geometry" and "CO2 geometry" to get a better idea! :)
H₂O represents a nonpolar molecule containing polar covalent bonds. Hence Option (A) is correct
What is Polar Covalent Bond ?A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond.
Consider the hydrogen chloride (HCl) molecule. Each atom in HCl requires one more electron to form an inert gas electron configuration.
Water (H₂O), like hydrogen Chloride (HCl), is a polar covalent molecule. When we look at a diagram of water , we can see that the two hydrogen atoms are not evenly distributed around the oxygen atom
Water (H₂O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule.Thus, This is an example of polar covalent chemical bonding.
Therefore, H₂O represents a nonpolar molecule containing polar covalent bonds. Hence Option (A) is correct

The area of a telescope lens is 6.668 × 103 mm2. What is the area in square feet (ft2)? Enter your answer in scientific notation
Answer:
[tex]7.13\times 10^{-2}\ ft^2[/tex]
Explanation:
The area of a telescope lens is 6.668 × 10³ mm²
We need to convert the area in ft².
We know that,
[tex]1\ mm^2=1.07\times 10^{-5}\ ft^2[/tex]
It means,
[tex]6.668 \times 10^3\ mm^2=6.668 \times 10^3\times 1.07\times 10^{-5}\ ft^2\\\\=0.0713\ ft^2[/tex]
or
[tex]0.0713\ ft^2=7.13\times 10^{-2}\ ft^2[/tex]
So, the required answer is [tex]7.13\times 10^{-2}\ ft^2[/tex].

A 170.0 g sample of an unidentified compound contains 29.84 g sodium, 67.49
g chromium, and 72.67 g oxygen. What is the compound's empirical formula?
The empirical formula : Na₂Cr₂O₇
Further explanationGiven
170 g sample contains :
29.84 g sodium, 67.49 g chromium, and 72.67 g oxygen
Required
The compound's empirical formula
Solution
mol ratio of elements :
Na : 29.84 : 23 g/mol = 1.297
Cr : 67.49 : 51,9961 g/mol = 1.297
O : 72.67 : 16 g/mol = 4.54
Divide by 1.297
Na : Cr : O = 1 : 1 : 3.5 = 2 : 2 : 7
Electrical energy is the amount of energy that an object contains due to kinetic energy
Answer:
The energy an object has due to its motion is called kinetic energy. Factors Affecting Kinetic Energy: the kinetic energy of an object depends on both its speed and its mass. The faster an object moves, the more kinetic energy it has.

How many atoms of silver are in a bracelet that has a mass of 13.94 grams?
Number of Silver atoms : N = 7.8 x 10²² atoms
Further explanationGiven
mass of bracelet : 13.94 g
Required
Number of atoms
Solution
Assuming the bracelet consists entirely of silver
mol of silver :
= mass : molar mass
= 13.94 g : 107,8682 g/mol
= 0.129
Number of atoms :
N = n x No(No = Avogadro's number)
N = 0.129 x 6.02 x 10²³
N = 7.8 x 10²² atoms

Describe what happens to a liquid's molecules as it boils and changes into a gas.
Answer:
the particels becomes loose and wild, making gas happen when it is heated up
Liquids evaporate faster as they heat up and more particles have enough energy to break away. The particles need energy to overcome the attractions between them. At this point the liquid is boiling and turning to gas.
