Proteins are considered as building blocks of the body, from structure, enzymes, transport of small molecules, hormones, and other bodily functions. People may have thought that these proteins are responsible for passing traits from generation to generation because there is evidence of function. For instance, a person with sickle cell anemia (problem with the protein hemoglobin) passes the trait to his child. Scientists back then hypothesized that proteins are responsible for heredity. But further research holds that untrue. First, proteins are complex and bulky molecules that has specific functions and a misplaced or deleted amino acid (amino acids are the basic units of proteins) may affect the function drastically. Having them be passed from one generation to another may produce an error in the amino acid sequence and therefore the function. Second, the entire number of proteins in the body are almost innumerable to be contained in one cell and determine functions. So the idea is that, there must be a molecule, with a structure simple enough to code for proteins, compact enough to fit in the cells' nuclei, and reselient to damage, hence DNA.

Farmers add nitrogen to their soil, in the form of fertilizers, in order to increase crop production. Which step in the nitrogen

Sloan [31]

Ans.

Nitrogen fertilizers are commonly used by farmers to increase crop production. Ammonium is the main component of nitrogen fertilizer, as it is easily assimilated by plants and provides nitrogen to them, while nitrate gets easily lost from the soil. During nitrogen cycle, ammonium is converted into nitrate by nitrification. So, nitrification inhibitors are used with to slow down the conversion of ammonium to nitrate to provide nitrogen for longer time.

Thus, 'to increase crop production, nitrification step of nitrogen cycle is preferred by farmers to block, or slow down.'

Answer: The average global temperature has increased by a little more than 1°. The temperatures we experience locally and in short periods can fluctuate. In the past, a one- to two-degree drop was all it took to plunge the Earth into the Little Ice Age. The strong warming trend of the past four decades likely reflects a shift

How are skepticism and open-mindness alike and different?

tatiyna

With skepticism and open-mindedness, they both revolve around the fact that they don't "confine" themselves in an idea.

However, the difference comes with the means of not confining themselves. With skepticism, you are questioning that idea and essentially, taking that idea with a pinch of salt. With open-mindness, however, you aren't questioning the idea but rather are willing to open yourself to other ideas aside from that singular idea.

Here's an example (it's simplified, but you should understand the difference):

Skepticism: I used to believe in idea A, however after scrutinizing it I'm starting to doubt idea A.

Open-mindness: I believe in idea A, however I want to understand ideas B and C as well.
