Biochemistry, molecular biology

After World War II, a multitude of discoveries were made at the interface between biology and chemistry - homework helper science . This includes the extensive elucidation of the reactions during photosynthesis and the clarification of the structure of DNA as the transmitter of genetic information. With molecular biology and genetic engineering, new specialist areas of natural science emerged.

With the help of X-ray structure analysis, the structures of complicated molecules could also be described, thus creating the basis for their synthesis. In this way, a variety of new drugs, pesticides or detergent additives have been developed - chemistry helper online . It was not only a question of the effect of the substances but increasingly also of their environmental compatibility. The eutrophication of water and the beginning of the depletion of the ozone layer indicated that nature cannot be burdened indefinitely with the waste products of human civilization.

In addition, physicists and chemists worked on developing new energy sources - hire someone to do my homework . Nuclear energy was still the focus of interest, even if the old idea of ​​environmentally friendly fuel cells has already been taken up again. The high level of development in materials chemistry and astrophysics made manned space travel possible in the 1960s.

from 1950
In the 1950s, DANIEL I. ARNON (1910-1994) was able to largely elucidate the light reaction during photosynthesis - especially the partial step of photophosphorylation. However, the biochemical processes are so complex that the exact course of the reaction is not yet fully understood even today.

Bear animals: real survivors
#Science Love it a bear animal like that? Have you ever encountered it? You don't think so. But I'm sure. The animal is an extreophile and tiny. With their 0.2 or 0.3mm you need eagle-eyed to see them. However, there are 1000 different species on Earth. They can be found in a variety of places. High in the mountains, deep or shallow in the Seas, in Tropical Rainforests and even Antarctica. They are also found in the Netherlands on beaches along the Oosterschelde. One time, a scientific scientist found them so interesting that he might want to study them more closely. After all, they had already been known to have had an evolution of 540 million years. So they already survived some extinctions. Like the extinction of the dinos and other prehistoric animals plus 4 previous devastations happened. The researchers didn't have a lot of trouble to click some of them. But had they left it up to them, the critters would have preferred to stay in their own familiar environment. For they were subjected to numerous barbaric trials, ocharity. Not fun for the critters. Baffling to the scientists! For example, some of them were placed in an extremely dry environment with less than 5% of their normal amount of water. And what did they do? They immediately created proteins that turned the parts of their body into a kind of vitreous composition. Which allowed them to protect their cells from drying out. If they put them back in a normal wet environment, they came back to life after 20 minutes. They froze them too, and when they were thawed, they frolicked again with their eight legs perky over the surface. Punishment after a few weeks they started laying eggs that all came out. They put them in an environment with bitterly low oxygen. They reduced their metabolism to near zero and returned to life as soon as oxygen came back to their disposal. The Scientists can only explain all of this trouble. Some thought they might have hit a meteorite here in the past. So they didn't think better than taking them to the International Space Station. There they were exposed to the freezing vacuum of Space and the cosmic rays. That too survived these tough creatures. Then they went a step further . Would they survive an impact on a planet? For that, they fired at a high speed in freezing state. They survived this too. Even though they should have defied a shockwave of 114.00 times greater than the air pressure on the Earth. At higher speeds, they kept the admittant. Some of them put under extremely germicidal ultraviolet light or bombarded with poison. Causing bacteria and roundworms to leave the 'axe' after 5 minutes The bear animals died only after about 24 hours. And there was one that even survived. As 'cherry on the pie' they also discovered that these extremophiles were able to run as fast as insects, and to each of them, their green poop is almost as long as their own bodies. Their poop is green because they mainly eat algae and shortst mosses. When all life on our planet is gone. Another 10 billion years on. Still crammed bear animals on it. Imagine if they have evolved into super intelligent beings in the meantime. Who, like humans, in minuscule format, had invented all kinds of. That would only be a cool discovery of larger living beings from somewhere out of the universe. The tiny super-survivors with their own civilization and culture on their own huge globe.
