<span>it was molecular structure of DNA this was appeared 1n April 1953 Watson and Crick presented the structure of DNA- Helix.it carried the genetic information. the DNA Molecule shaped in twisted ladder.franklin produced an X- ray photograph.
DNA structure is made of molecules called nucleotide. Watson and crick also work on 3-D structure of DNA. this mark the history in molecular biology to understanding the genes control and genetic information.they also work on cell.they use stick and ball to understand to test their idea.</span>
I think it’s asking which is not a compound cause all of them are compounds the only one that isn’t a compound is carbon dioxide gas
The correct answer is 2.
The scientific knowledge is constantly growing. The main advantage of the scientific method is that nothing is absolutely true and unquestionable.
With each new hypothesis and experiment, scientists get a little bit closer to the truth about the natural world. Some parts of the scientific knowledge stand through time and new experiments only confirm them. But often, the new research finds new aspects or disproves parts of the previous finds, so the understanding of that phenomenon changes.
Answer:
These phosphate groups are linked to one another by two high-energy bonds called <u>phosphoanhydride bonds</u>.
Explanation:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).
