The acronym 'DNA' stands for deoxyribonucleic acid.
DNA is used to 'code' the genetic makeup of all living organisms, and is found inside the nucleus of the cell(Eukaryotes) or just floating in the cytoplasm of the cell(Prokaryotes). DNA is made up of 4 different pairs of base molecules(nucleotides) that are slightly different from another. The similar molecule structure RNA(ribonucleic acid) differs from DNA in that RNA nucleotides are just slightly different from the nucleotides of DNA. This difference is that RNA nucleotides have a hydroxide group(OH) where the DNA nucleotides just have a hydrogen atom.
Because the DNA nucleotide doesn't have the hydroxide group it has one less oxygen than RNA nucleotides do. This is where DNA derives the prefix "deoxy-," meaning "without oxygen."
The prefix "ribo-" is given to molecules with a certain configuration of a set of 3 consecutive but not necessarily contiguous CHOH(asymmetric) groups.
The combined form "nucleo-" is used to imply something that has to do with the nucleus, such as the nucleus of a cell where DNA is stored in Eukaryotes.
And finally, the ending of the acronym: "acid." DNA is an acid because the 4 nucleotides each contain a phosphate group, which are acidic.
And thus, we get our answer: deoxyribonucleic acid, and the meaning:
deoxy-ribo-nucleic acid
(without oxygen) + (has 3 CHOH groups) + (in/of the nucleus) + (acidic)
Thus, DNA is a molecule is basically an acidic molecule residing in the nucleus with 3 CHOH groups and is missing oxygen atoms.
I know this isn't really what you're looking for, but honestly I had a great time doing a little research into the name!
Hope this explains it a little! c;

I think its the length of its year
Answer:
The answer to your question is 1.25 M
Explanation:
Data
Molarity 1 = ?
Volume 1 = 60 ml
Molarity 2 = 0.5 M
Volume 2 = 150 ml
Process
1.- Write the dilution formula
Molarity 1 x Volume 1 = Molarity 2 x Volume 2
-Solve for Molarity 1
Molarity 1 = Molarity 2 x Volume 2 / Volume 1
-Substitution
Molarity 1 = (0.5)(150) / 60
-Simplification
Molarity = 75 / 60
-Result
Molarity = 1.25 M
Answer:
Ice and water on the ground affect incoming solar radiation by reflecting 4 percent of solar radiation that reaches the surface. ... When the sun angle is high and water is liquid notice, there is less reflection that takes place.
Answer is: the combined ionic bond strength of CrCl₂ and intermolecular forces between water molecules.
When chromium chloride (CrCl₂) is dissolved in water, the temperature of the water increases, heat of the solution is endothermic.
Dissociation of chromium chloride in water: CrCl₂(aq) → Cr²⁺(aq) + 2Cl⁻(aq).
Energy (the lattice energy) is required to pull apart the oppositely charged ions in chromium chloride.
The heat of hydration is liberated energy when the separated ions (in this example chromium cations and chlorine anions) attract polar water molecules.
Because the lattice energy is higher than the heat of the hydration (endothermic reaction), we can conclude that bonds between ions are strong (the electrostatic attraction between oppositely charged ions).
