As my interests lay more in physiology and biochemistry than genetics, Leo suggested that I focus on mechanisms of nitrogen regulation of chloramphenicol biosynthesis in Streptomyces venezuelae. Chloramphenicol, a broad-spectrum ribosomotropic antibiotic discovered at Parke, Davis & Co. in 1947, had ...
Apart from that, the C3, C4 cycle, Kranz anatomy, Glycolysis and Krebs cycle, Photoperiodism, Bulk movement in Phloem, Mineral deficiency & Nitrogen cycle, Transpiration pull, and ETS complexes are some more topics to concentrate on. Plant Kingdom: This chapter will cover general topics such ...
In concert with improvements in personal hygiene and public sanitation, the discovery and development of antibiotics during the latter half of the last century has reduced substantially the morbidity and mortality associated with bacterial diseases. Howe
It's crazy, if you think about it. The God of the universe - the creator of nitrogen and pine needles, galaxies and E-minor - loves us with a radical, unconditional, self-sacrificing love. And what is our typical response? We go to church, sing songs, and try not to cuss. —Franc...
When we knew of only four “elements,” it was pretty clear that plants needed three of them – earth, water and air – to grow. With better science, the list grew longer. Nitrogen, phosphorous and potassium were identified as primary nutrients and, on the second tier, sulphur, magnesium...
Electrocatalytic carbon-nitrogen coupling of carbon dioxide and nitrate, under ambient conditions, offers a sustainable and promising approach to urea synthesis. Up to this point, the influence of catalyst surface characteristics on the molecular adsorption structure and the efficiency of electrocatalyti...
Clothes that are well made will be the last for you to choose. B. Clothes that are well made are mostly longer than cheap ones. C. You can wear well-made clothes for a longer time. D. You can wear well-made clothes for a long time if you wear them at the last time. ...
阅读理解 The gray-haired lady can’t wait to leave the building to search for her dad.Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago. Not all cases of Alzheimer’s disease look like this, but Alzhe
The estimate was derived from monetizing the damage of major air pollutants — sulfur dioxide, nitrogen oxides, ozone, and particulate matter –on human health, grain crops and timber yields, buildings, and recreation. The figure does not include damages from climate change, harm to ecosystems, ...
Thanks for the responses. Between the addition of the leguminous plants and the increase in organic matter in the soil due to mulch and buried wood, I am looking forward to seeing a very interesting transformation in our soil. Since these things all take years, and time is something you ca...
