BRAINLIESTTTT ASAP!!!<br><br> What roles do society, politics, and economics play in science?
ser-zykov [4K]
So what roles do society, politics, and economics play in science?Economics determines how much money is available to fund scientific research. Certain federal grants come directly out of the national economy, which determines if certain research projects can continue or are cut off.Politics affect science by passing some bills that directly affects science, congressmen can determine whether those funds from the economy will be used for research or not. Just a side note: wealthy lobbyists control alot of what politicians do, by donating millions into their election campaigns. Society affects science by our citizens democratically electing those politicians that we think will or will not endorse scientific research projects. For example, embryonic stem cell research has been under fire by conservatives for taking future babies' cells to study. Liberals, however, tend to be in favor of change and new advances scientifically
_____________________________________________________________

if you need it shorter "Society, made up of the country's citizens, can influence science by electing politicians (president and congressmen); the politicians can then affect the economic funding of scientific research, either by increasing or decreasing government grants to scientific projects."

16. The goals of biodiversity conservation include all of the following EXCEPT (1 point) protecting individual species. introduc
ludmilkaskok [199]
The best answer is: introducing exotic species into <span> new environments. This can be actually bad, as new species can actually reduce the biodiversity in the environments to which they're introduced</span> , such when cats hunt indigenous birds.

I was a bit thinking about the last option too: making sure local people benefit from conservation efforts. This is not one of the classical goals of the conservation efforts, but since the previous one is definitely correct, i don't this one is. (it's not that it's not a goal, but it isn't a main focus)

Describe the Watson and Crick model of DNA structure. How did it fit the data provided by Chargaff and the X-ray diffraction pat
icang [17]

DNA model given by Watson and Creek in the year of 1953 gave a very detailed study regarding the structure of B DNA which is valid till date and is essentially corroborating with Chargaff's data and Xray diffraction pattern.

<h3><u>Explanation:</u></h3>

The DNA is the most common nucleic acid found in the living organisms as a genetic material. As stated by Watson and Creek, this DNA contains a double helical structure with two sugar phosphate backbones and the nitrogen bases getting projected from it inwards. The backbones are formed of ribose sugar and phosphate and joined together with a phosphodiester bond. The ribose sugar is attached to phosphates at its 3' and 5' Carbon atoms. The nitrogen bases found in DNA are Adenine, Guanine, Thymine and Cytosine. The Adenine has two hydrogen bonds with thymine and guanine has 3 hydrogen bonds with cytosine.

Each full turn of a helix is 34A and each base pair is 3.4A apart. The distance between two strands of DNA is 20A.

Chargaff's rule regarding the equal amount of adenine and thymine as well as guanine and cytosine is matching with this structure. All the other rules also do match with this DNA structure.
