I believe your answer would be an atom.
Classical Greek philosophers, notably a man named Democritus, who lived in Greece in the 5th century was interested about the world around us. He thought up a very simple situation: If you cut something in half (like a log), the two pieces left can cut into even smaller pieces, which can cut again, and so on down to splinters. Yet, even a splinter could be cut in half. He questioned, "Whats the smallest that something can be cut?" He answer was that, at some very, very small size, you would reach a piece of the object that was 'atomos', Greek for uncuttable.
If you had a block of iron and let's say you kept cutting it into pieces, you would, in theory, reach an extremely small piece which could absolutely not be broken down-- it was the basic building block of iron. This was, and is, a powerful idea that gives reason for all sorts of things related to chemistry and the world we live in-- like how our bodies digest food <span>(since everything is made up of just a limited number of types of atoms (the elements), we can ingest food in one form, break the food down into small groups of atoms, and put the atoms back together as parts of our growing bodies). Modern chemistry is formed on atomic theory. Atoms are almost unbelievably small, one of your hairs is about a million atoms wide, and a speck of dust you can see might as well contain trillions of atoms.
I got my answer and reasoning from a website called "scienceline.ucsb.edu". It goes way more into depth for your answer, you might want to check it out. I just chose bits of info that directly give reasoning as to why your answer would be An atom.
Good luck on your assignment. </span>
Answer:
I believe the correct answer is<em> </em><u><em>C. mRnA translation. </em></u>
Explanation:
Because the gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.
Answer:
DNA is known as the genetic material of all the organisms except some viruses. DNA is made of four nitrogenous bases, pentose sugar and the phosphate group.
1. Watson and crick meant that DNA shows the complementary base pairing in which adenine binds with thymine and cytosine binds with guanine. This base pairing has allowed the single DNA stranded to carry the information that are necessary for the synthesis of the complementary daughter strand.
2.The separation of the strand should be done in such a way that friends should get each single strand of DNA. The information stored in the DNA is available in the single strand of DNA.
Answer:
A. gas molecules having three or more atoms
Explanation:
A greenhouse gas has the property to absorb infrared radiation and radiating it back to the earth surface.
A greenhouse gas must have three atoms or more, that will help the gas to absorb infrared radiation and restricts its way out of the atmosphere. some example of greenhouse gases are methane (CH4), carbon-dioxide (CO2) and nitrogen oxide (NO2).
Hence, the correct answer is "A".
